From: Info-IBMPC Digest <Info-IBMPC@USC-ISIB> Info-IBMPC Digest Sunday, 15 April 1984 Volume 3 : Issue 42 This Week's Editor: Billy Brackenridge Today's Topics: Larger Hard Disks & Controllers Portable PC Gosling Emacs on the PC Tall Tree JRAM2 Assemblers DisplayWriter PC Connection ---------------------------------------------------------------------- Date: Fri, 13-Apr-84 23:50:04 PST From: Pete Carah <vortex!pete@RAND-UNIX.ARPA> Subject: Larger Hard Disks & Controllers To: info-ibmpc@isib I have been using a Xebec S1410A (purchased from Hamilton Electro Sales but they are also sold through other distributors) for a year now, and have had no trouble with it except that it won't support a Syquest removable without a different ROM, and thus it may be hard to mix a removable and a non-removable drive on the same controller. I don't know if a normal drive will work with the Syquest ROM, however. (It won't if you formatted it with the normal ROM). These controllers will support at least 1024 cyls and 8 hds as they come. I have been using Miniscribe 17meg (formatted) drives (4hd, 480 cyl) with this controller, and tested a Maxtore (118 meg formatted) with it (though the stock ROM makes addressing of this drive difficult, since the drive uses the reduced write current line as a head select). The controller ran about $295 and host adapter (SASI) about $150 a year ago. To do this yourself you need a good source of ribbon cable and connectors of 3 sizes (20, 34, and 50 pin). All of the power connectors are compatible with 5-1/4 inch floppies (AM-P 4 pin). The drive market has changed a lot since I looked - I could suggest looking in Mini-Micro Systems, Computer Design, or that type of magazine - there are now several half-height 30 meg drives available. The controller used in (at least early) XT's is also a Xebec (1210) which is not normally listed in Xebec catalogs. It is almost (but not quite - trust IBM) program compatible with the SASI version. If you get it from Xebec, you don't get the IBM Bios ROM. The separate controller and host adapter is easier to use if you don't have an XT power supply since it is difficult to cable external drives to the built-in controller, and difficult (though not impossible) to bring drive power into the PC. -- Pete ------------------------------ Date: 8 Apr 84 11:49:11-PST (Sun) To: info-ibmpc @ Usc-Isib From: randy@washington Subject: Portable PC The following information comes from an article entitled "IBM Portable PC Not All That Compatible" on p. 5 of the March 20th, 1984 issue of PC Week. The major thrust of incompatibility is that the IBM Portable PC uses the slower Qume drives, which requires DOS 2.1, which slows down disk accesses. Therefore software that won't run under DOS 2.1 will not run on the Portable. This includes "BPI Accounting", Peachtree's "General Ledger", Sierra Online's "Homeword", SofTech's "UCSD p-system", and "Turtle Power." It appears that version IV.1 of UCSD p-system will run under DOS 2.1. Another area of incompatibility is the screen. Programs that try to take advantage of the monochrome screen's higher resolution (720X350) will not work in the Portable. One example: "101 monochrome mazes." It appears that the Portable only has one full-size expansion slot. A few other small expansion slots are provided. Does this machine live up to the Compaq? Randy. ------------------------------ Date: 14 April 1984 17:54-EST From: Steven T. Kirsch <SK @ MIT-MC> Subject: Has anyone tried Gosling Emacs on the PC To: info-ibmpc @ USC-ISIB I saw an ad for this from Unipress. Requires 384K and costs $375, if memory serves me correctly. Has anyone tried this? ------------------------------ Date: 14 Apr 1984 18:29:43 PST Subject: Gosling Emacs on the PC From: Billy <BRACKENRIDGE@USC-ISIB> To: Steven T. Kirsch <SK@MIT-MC> ISI has it on order. I spoke with the people at Unipress and they say it will be ready for shipment about the same time a purchase order clears campus. I asked about mouse support. There is none but they were interested. This summer they expect a stripped down version suitable for use on a floppy drive only system. I am told that despite the huge size that once the thing is loaded it runs at a pretty good clip and provides all features of a true Gosling Emacs. ------- ------------------------------ Date: 14 Apr 1984 22:42:07 PST Subject: Tall Tree JRAM2 From: Billy <BRACKENRIDGE@USC-ISIB> To: info-IBMPC@USC-ISIB Tall Tree Systems has recently announced JRAM-2. This memory board is similar to to the original JRAM card in that it has the same memory mapping capability that allows one to expand RAM on the PC to beyond the 1 MB address space of the 8086. The new card can use either 64K RAM chips or the new 256K RAM. Up to 4 boards can be placed in a system. With 64K RAM chips each board contains 512K memory for a total system size of 2 megabytes. Using 256K chips 8 megabytes of memory can be placed in a PC. As MS-DOS with Tall Tree modifications can only use 704K, the rest of the memory is currently used as RAM disk or print spool buffer. I have been informed that Multi Job will be supporting Tall Tree memory mapping. This should allow one to run multiple copies of large memory Lotuses if one were so perverse. There is also room on JRAM-2 for a daughter card. Currently one daughter card contains a calendar clock, parallel port, and serial port. Another has two serial ports. Even with the daughter board installed JRAM-2 will fit in an XT narrow slot. One problem with the PC design is the shortage of interrupt vectors. The Tall Tree system allows one to run up to 8 serial lines on a PC. Multiple serial ports can share a single interrupt vector. Interrupt software must poll each serial port to find which serial line caused the interrupt. Each card has a 9 pin D connector and a standard 25 pin D connector. A ribbon cable adaptor optionally changes the 9 pin D connector to a 25 pin connector if desired. Currently other multi function cards support multiple connectors by running ribbon cables out the back of the PC. The Tall Tree approach should make for a neater looking back side and less RF noise. A JRAM-2 board with no memory chips retails for $199. The clock, serial port, parallel port option brings the price up to $399. I don't have a price for for the two serial port option.

I believe "Tools" means a linker and debugger. This package is reputed to run under MS-DOS. I have been unable to find a software store in Southern California where anyone knows what an assembler is much less differences between the IBM Assembler and Digital Research Assembler. The Programmer's Shop (a mail order house) carries this product as well as the Microsoft Assembler 1.25. I have never seen in any Microsoft catalogues admission that they actually wrote what is billed as the IBM Macro Assembler. If I had been able to purchase an assembler from Microsoft I would have done so long ago and sent them a book full of bugs. It might not do any good, but sending bug reports to IBM doesn't even make one feel better. In the mean time I tried purchasing the Seattle assembler. I gather Seattle is a subsidiary of Microsoft. If I were Microsoft I wouldn't have admitted to having written the Seattle assembler either. Has anyone tried the Digital Research assembler and is it compatible with the specification of the IBM assembler? ------- ------------------------------ Date: 14 Apr 1984 20:39:14 PST Subject: DisplayWriter PC Connection From: Billy <BRACKENRIDGE@USC-ISIB> To: info-ibmpc@USC-ISIB Recently IBM has made some announcements regarding cross support between the DislpayWriter and PC. The DisplayWriter is IBM's stand alone word processor. As it has a nearly identical screen and keyboard as the PC, and the internal processor is an 8086, cross support was pretty much a natural move. The following official IBM announcement describes two communication options for transferring files from DisplayWriters to PCs. What is only alluded to in this document is that DisplayWriter software is now available which runs directly on the PC. This software is similar to the popular MultiMate which emulates a Wang word processor in that a typist already familiar with an existing word processor need not learn new commands in order to move to the cheaper PC. Revisable Form Text Document Content Architecture (RFTDCA) is IBMese for DisplayWriter internal file format. IBM is now supporting this file format on the PC and DisplayWriter. I suspect this will become a word processor standard similar to the Software Arts DIF format for spread sheets. Currently Flagstaff Engineering is the only company I know of which makes a RFTDCA to Wordstar format converter, but I suspect there will be a host of programs to translate between various word processor formats. IBM announces the IBM Personal Computer DisplayComm Binary Synchronous Communications licensed program, a member of the IBM DisplayWrite Series, providing batch data transmission capabilities for the IBM Personal Computer (5150), Personal Computer XT (5160), and IBM Portable Personal Computer (5155). This program supports data exchange with the IBM Displaywriter, IBM 6670 Information Distributor, IBM 5520 Administrative System, IBM Office System 6, and suitably programmed host computers, as well as with other IBM Personal Computers equipped with DisplayComm Binary Synchronous Communications (BSC). Multiple data formats are supported,including the revisable form text document content architecture data stream. 6024187 HIGHLIGHTS ? Communicates revisable form text document content architecture (RFTDCA), page image text, or card image text. ? Communicates DOS ASCII files between IBM Personal Computers that have IBM Personal Computer DisplayComm Binary Synchronous Communications. ? Stores up to eight communication setups. ? Provides a send queue of up to 20 documents/files. ? Line speeds of up to 4800 bps are supported. ? Attended or unattended operation. ? Utilizes switched or non-switched lines. ? Provides IBM 2770/3780 and IBM 2780 emulation. DESCRIPTION IBM Personal Computer DisplayComm Binary Synchronous Communications (BSC) is a program for the IBM Personal Computers (IBM Personal Computer, IBM Personal Computer XT, and IBM Portable Personal Computer) that provides the functions necessary to transmit documents or data over a communications line. IBM Personal Computer DisplayComm BSC provides batch data transmission at line speeds of up to 4800 bps. IBM Personal Computer DisplayWrite documents can be transmitted in RFTDCA format to another IBM Personal Computer that has IBM Personal Computer DisplayComm BSC, an IBM Displaywriter, or suitably programmed IBM host computer. DisplayWrite documents may also be transmitted in page or card image to another IBM Personal Computer that has IBM Personal Computer DisplayComm BSC, an IBM 6670 Information Distributor, IBM 5520 Administrative System, IBM Office System 6, or suitably programmed IBM host computer. Additionally, IBM-PC DOS ASCII and object files may be transmitted to other IBM Personal Computers that have IBM Personal Computer DisplayComm BSC. Print level 7-bit ASCII documents received may be optionally converted to DisplayWrite 2 format or stored as PC DOS ASCII files. IBM Personal Computer DisplayComm BSC provides IBM 2770/3780 and IBM 2780 emulation. Switched and non-switched lines are supported. Unattended operation is facilitated by support for auto-answer modems and by an optional exchange of identification information with another DisplayComm BSC program, or with suitably programmed devices. IBM Personal Computer DisplayComm BSC is similar in function to the Binary Synchronous Communications program (5608-SR2) for the IBM Displaywriter System. Differences exist to accommodate implementation under the IBM Personal Computer DOS. SCHEDULE The planned general availability date is April 1984. TECHNICAL INFORMATION SPECIFIED OPERATING ENVIRONMENT HARDWARE REQUIREMENTS: DisplayComm BSC is designed to operate on the IBM 5150 Personal Computer, IBM 5160 Personal Computer XT, or IBM 5155 Portable Personal Computer with: ? A minimum of 256KB of memory ? Two double-sided diskette drives or one double-sided diskette drive and a fixed disk drive ? IBM Binary Synchronous Communications Adapter (feature number 2075) ? One of the following 80-column displays (or equivalent): - IBM 5151 Monochrome Display and the IBM Monochrome Display and Printer Adapter - IBM 5153 Color Display and the IBM Color/Graphics Monitor Adapter - Self-contained display for IBM Portable Personal Computer. ? User-supplied modem, cable, and communications network. ? For document printing, one of the following (or equivalent), including appropriate prerequisites: - IBM 5152 Model 1 Matrix Printer - IBM 5152 Model 2 Graphics Printer - IBM 5182 Model 1 Color Printer (supported as an IBM 5152 Model 2 Printer) - IBM 5218 Models 3 or 4 Printwheel Printer (requires at least 320KB of memory). Concurrent communication and printing is not supported. SOFTWARE REQUIREMENTS: DisplayComm BSC requires IBM Personal Computer Disk Operating System (DOS) Version 2.1 for operation. COMPATIBILITY: An IBM Personal Computer using DisplayComm BSC and DisplayWrite 2 (feature number 4189) can interchange information with an IBM Displaywriter using the Displaywriter Binary Synchronous Communications licensed program (5608-SR2). Exchange of documents in the Document Content Architecture revisable-form-text data stream is supported. The level of compatibility for editing and printing RFTDCA documents on IBM products is dependent upon each product's functional capabilities and implementation. Compatibility documentation describing the level of interchange between IBM products will be available in the third quarter of 1984. An IBM Personal Computer using DisplayComm BSC and DisplayWrite 2 can exchange information with the IBM 5520 Administrative System with communications support, or with an IBM 6670 Information Distributor or Office System 6 with binary synchronous communications support. DisplayComm BSC provides the capability to convert DisplayWrite 2 documents to and from either EBCDIC page image or EBCDIC card image for exchange with these devices. Limitations for this exchange are documented in the DisplayComm BSC reference manual. An IBM Personal Computer using DisplayComm BSC can interchange data with another similarly equipped IBM PC. Any DOS file, including object files, can be transmitted and used by the receiving system as if it had been created on that system. Any exchange of data for use by a different software program and any transmission of copyrighted information are the responsibilities of the user. DisplayComm BSC may also be used for exchange of data with suitably programmed host computers that support IBM 2770/3780 or IBM 2780 communication protocols. DisplayComm BSC can send and receive files in any DOS format. In conjunction with DisplayWrite 2, DisplayComm can also send and receive EBCDIC page image, EBCDIC 80-column card image or RFTDCA data streams. It is the customer's responsibility to determine the ability of the host program to use any of these data streams. TECHNICAL ASSISTANCE: The IBM Personal Computing Assistance Center (Boca Raton) will continue to support eligible IBM customers. PACKAGING: DisplayComm Binary Synchronous Communications is distributed with the following: ? Program diskette ? Reference manual ?

This cable attachment allows the transfer of documents and files between a Displaywriter and a single IBM Personal Computer. This attachment also allows a Displaywriter to connect with the IBM Personal Computer Cluster, using an IBM Personal Computer as an interface to the cluster. Displaywriters can share a fixed disk and exchange messages with other Displaywriters or IBM Personal Computers attached to the cluster. Editable document exchange is supported among IBM Personal Computer DisplayWrite 2 licensed programs and Displaywriters. This Convenience Kit is available for installations by customers in business, commercial, or industrial environments, and not in residential environments. HIGHLIGHTS ? Connection of the IBM Displaywriter and the IBM Personal Computer, the IBM PCjr, the IBM Portable Personal Computer, or the IBM Personal Computer XT. ? Interchange of revisable form text document content architecture (RFTDCA) documents among IBM Personal Computers that use DisplayWrite 2 (feature number 4189) and Displaywriters. ? IBM Personal Computer DOS print files sent to Displaywriter are converted to Displaywriter text document format for editing, printing, or combining with other documents. ? IBM Displaywriters used with the IBM Personal Computer Cluster can: - Share a fixed disk - Exchange messages - Share and exchange RFTDCA documents - Receive ASCII files. ? Optional alternate foreground execution on Displaywriter allows hot-key switch between Personal Computer attach functions and Textpack functions. DESCRIPTION The IBM Displaywriter/Personal Computer Attach Convenience Kit includes a special attachment cable, a program for the IBM Displaywriter, and a program for the IBM Personal Computer, the IBM Personal Computer XT, the IBM PCjr, or the IBM Portable Personal Computer. Two categories of functions are available using this kit: those available to all users of the kit, and those available when the IBM Displaywriter is used with a cluster. All functions described in this announcement as being available for the IBM Personal Computer (IBM PC) are also available for the IBM Personal Computer XT, the IBM Portable Personal Computer, and the IBM PCjr, unless otherwise specified. The IBM Displaywriter/Personal Computer Attach Convenience Kit is available for installations by customers in business, commercial, or industrial environments, and not in residential environments. DISPLAYWRITER - PERSONAL COMPUTER ATTACHMENT FUNCTIONS File and document transfer between the IBM Displaywriter and the IBM Personal Computer are accomplished using IBM PC DOS file commands at the Displaywriter. The Directory command can be used to display the directories of either Displaywriter diskettes or IBM PC diskettes. The Delete command may be used to delete documents and files from Displaywriter or IBM Personal Computer diskettes. To transfer documents and files, the Copy command is used. When copying documents from the IBM Displaywriter to the IBM PC, the documents are converted to RFTDCA format and stored on the IBM PC. Reportpack files that are copied are converted to a special interchange format for storage. Chartpack documents may not be copied to an IBM Personal Computer. Documents and files copied from the IBM PC to Displaywriter are converted as follows: ? IBM PC RFTDCA documents are converted to Displaywriter document format. ? Reportpack files are converted to Displaywriter internal format. ? DOS ASCII files are converted to IBM Displaywriter document format. Some editing of the resulting document may be required. For best results, it is recommended that only print files be transferred. After conversion, the document may be printed, edited, or combined with other documents. Optional alternate foreground execution is available on Displaywriter, allowing the user to switch (hot-key) between Displaywriter/Personal Computer attach functions and Textpack 4 or Textpack 6 functions, such as creating or revising documents, pagination, and spelling verification. An additional 128Kb of memory is required over that required for the IBM Textpack licensed program being used. CLUSTER ATTACHMENT FUNCTIONS The IBM Displaywriter/Personal Computer Attach Convenience Kit allows the IBM Displaywriter to access the functions provided by the IBM Personal Computer Cluster Program. The IBM Personal Computer attached to the Displaywriter is used as an interface device, and must have the appropriate hardware prerequisites to execute the IBM Personal Computer Cluster Program. The IBM Personal Computer used for cluster interface for a Displaywriter may be used for other functions when not acting as the interface. In situations where the IBM Displaywriter is to be attached to the cluster for long periods, the use of a dedicated IBM Personal Computer may be advisable. All functions described in the previous section are available to a Displaywriter attached to a cluster. In addition, the following functions are available using the IBM Personal Computer Cluster Program. The Displaywriter can share an IBM Personal Computer fixed disk with other users of the cluster. Data must be copied from the fixed disk to the Displaywriter diskettes to be accessed by IBM Textpack licensed programs or by Displaywriter feature programs. The Displaywriter and the interfacing IBM Personal Computer will share a single private volume on the disk server unit. Sharing of data on a private volume can be limited by the owner of that volume. Data copied between the Displaywriter diskettes and the fixed disk will be converted as described in the previous section. The information transfer function of the IBM Personal Computer Cluster Program can be used by the Displaywriter operator to send or receive files. Data transferred to or from the Displaywriter diskettes will be converted as described in the previous section. The Displaywriter and the interfacing IBM Personal Computer share a single cluster address. Interchange of revisable form text document content architecture (RFTDCA) documents among Displaywriters and IBM Personal Computer DisplayWrite 2 is supported through the facilities provided by the IBM Displaywriter/Personal Computer Attach Convenience Kit and the IBM Personal Computer Cluster Program. Interchange can be accomplished either through a shared private volume or through file transfer. The level of compatibility for editing and printing RFTDCA documents on IBM products is dependent upon each product's functional capabilities and implementation. The Displaywriter operator can send and receive messages. The Displaywriter shares a single message log with the interfacing Personal Computer. The broadcast capability is also available. Please refer to the IBM Personal Computer Cluster Program announcement dated February 16, 1984, for further information on the capabilities, restrictions, and prerequisites for cluster operation.
