The cost is $500 per attendee. This includes a Windows Software Development Kit, retail copy of Windows and a seminar notebook. Microsoft Windows is dramatically changing the way today's computer users interface with application software...blah blah blah... ...As an industry leader, it is our responsibility not only to develop new technology, but also to provide you with the information you need to take advantage of it... This seminar is a unique forum that offers you the opportunity to communicate directly with our Windows experts. They each have in-depth experience with Microsoft Windows. Each will talk about his area of expertise and share his insights on Windows. ... Please keep in mind that most of the sessions are technically oriented. ...To register...or to learn more about the seminar simply call our representative, Sorenson & Company at 206-622-7405. ------------------------------ Date: Sun, 5 Oct 86 22:41 EDT From: Hess@MIT-MULTICS.ARPA Subject: Ron Katreil: Tandon 20Mb drives To: INFO-IBMPC@B.ISI.EDU I've not used the PC's Limited version of the Tandon w/WD controller, but have been using the same model Tandon from Qubie' with their BT controller (don't remember whose chips actually are in the board). The Tandon has performed reliably for the past year, and I have purchased a total of 3 of them now. Tandon problems are: after 6 months, the bearing starts to whine, where the little static-drainer metal piece drags on the bearing post (same as most other whiners), and in some instances, the Tandon will not complete power-on self-test, shutting itself down because of power supply fluctuation, presumably low voltage. Turning the machine off, waiting a second, and turning it back on again a second time starts up the drive without fail. They run kind of hot, but so do most half-height 20Mb drives; I use two of them stacked side-by-side with no trouble, and have also stacked a floppy on top of one with no trouble either. They are rumored to run with lower power than Seagate 225. (N.B. My latest Tandon, 4 months old, neither whines nor ever fails power-up. Luck, or design change? I dunno.)

The company that produces it has it available for several CPUs and the AT may be among them. If not, for a fee they will do custom ports. It is sold by: Elan Computer Group 260 Alta Vista Avenue Los Altos, CA 94022 (415) 948-8193. -- ------------------------------------------------------------------------------ A million here, a million there ... they all add up. ------------------------------------------------------------------------------ Jeffrey A.

It generates a non-maskable interrupt. While I am not familiar with the specific products such as ATRON or PERISCOPE, I believe that hardware assistance generally means an adaptor card for the debugger which monitors the CPU state directly (one of them plugs into the math coproc slot for intimate contact with the CPU). These cards do not come cheap, which is why I am not directly familiar with them. The advantages of this approach include: 1. The debugger can reside on its own card, in its own memory, in a place where a runaway program cannot accidentally overwrite it. Thus, your system may be trashed, but the debugger still runs to do post-mortum debugging. 2. By monitoring the hardware directly, you can determine when a given location is being stored to. For example, if the symptom of your bug is that part of your program, or DOS itself, is overwritten, you can have the debugger trap when that location is stored upon. Thus you can find the error in your program, which is usually a bad pointer. Such problems are VERY difficult to find without such a card. Of course, if a protected-mode DOS ever comes out, it will be impossible to overwrite DOS with a runaway pointer; such attempts would presumably be trapped by the hardware. It would still be a useful tool for finding where the program overwrites itself. The PC Tech Journal frequently runs ads on these types of products.

Calamai" <phcalamai%water.waterloo.edu@CSNET-RELAY.ARPA> Subject: IBM-PC to Laserwriter+ Cable Info Needed To: info-ibmpc%usc-isib.arpa@CSNET-RELAY.ARPA I need to establish a path from my IBM-PC to the Apple Laserwriter Plus in order to use Textset's PostScript Printer Driver for IBM-PCs....can anyone out there give me the pin assignments and suggest sources for any (unusual) parts?

(1.) Does anyone have or know where I can get the schematics to this board ? (2.) Is it worth restoring ? I can get an AST clone for $90 that seems to be quite reliable. Thanx in advance Gerard Hynes ------------------------------ Date: Mon, 6 Oct 86 08:31:54 PDT From: koen@CS.UCLA.EDU (Koenraad Lecot) Subject: Screen Generator for 132 Column Display Would appreciate any pointers to Turbo Pascal screen generation software that allows for 132 columns, i.e. could be used on monitors such as the WYSE-700. If such a thing does not exist, how can I get 132 column output in Turbo ?

Is there anybody out there who knows any bugs in this compiler? I'm anxious to know! Please mail to me directly. When I receive enough response, I'll summarize to Info-IBMPC.
