[net.micro.pc] 3270-PC and XT/370

At the IEEE personal computer conference, I saw an IBM 3270-PC.

The IBM 3270 was good. Originally, the IBM person there booted the
system without a diskette in the drive, so it started up in cassette
BASIC. The screen quality was at least as good as that of the
monochrome display, but in color. From BASIC, however, it doesn't do
graphics. It acts like a monochrome, except, that instead of
underlining, etc. it has the colors used on the color card.

The keyboard was a superset of the IBM PC keyboard. Even so, the
layout was a world better. There were nice big return and shift
keys, and the keys were easier to press. There are legends all
over the place on the keys; blue legends are for IBM PC specific
usages. There are twenty extra function keys in two rows across
the top. IBM sells this keyboard seperately for $295. However,
I looked in the back, and the keyboard was plugged into a
card in a feature slot; a cable came from the card and plugged
into the normal place for the keyboard.

The 3270 can have 7 windows; 4 for terminals, 2 for local scratchpads,
and 1 for an IBM PC. The one for the IBM PC only works with programs
that only use the ROM-BIOS and PC-DOS for screen addressing.
This is necessary, but severely limits the usage.

According to IBM literature, the 3270 has "advanced screen management"
which allows the user to move windows, change the sizes of windows,
select background colors, define combinations of windows in up to
ten logical screens, define user-controlled display area to
view a presentation space (which logically represents a host [upto
3440 characters] or a local session [2000 characters]). Copy between
presentation spaces, transfer binary, EBCDIC, ASCII files, etc. If
anyone has any questions, I have the product announcement; address
mail to MFARBER@UDEL-RELAY.

IBM has several models from $4290 through $7180. The IBM person
said that a PC can NOT be upgraded to a 3270.

They didn't have it there an XT/370 there, but they had the product
announcement for it. (Delivery is 1Q '84). I will quote from the
beginning of the product announcement: "IBM announces the IBM Personal
Computer XT/370, an extended version of the IBM XT. The IBM PC is a
System/370 workstation which can interact with a System/370 host.
When the new IBM Virtual Machine/Personal Computer licensed program
is installed, many unaltered CMS Sys/370 programs can run on the
workstation. System/370 functions have been achieved while mainting
IBM PC compatibility." An XT can be upgraded to an XT/370. IBM
has a special Expansion Unit for the XT/370. I have the product
announcement for that, too if anyone has any questions.

[Adapted from Oct. 18 annoucement by IBM]

The IBM 3270 Personal Computer (3270-PC) combines the interactive
functions of the 3270 display and the compute power of the IBM
personal computer.  The 3270-PC can display 7 separate windows
simultaneously -- 4 with data from host computer applications, 2
electronic note pads, 1 window running IBM PC DOS 2.0.  The unit
connects by coax cable to a 3274 controller at the host mainframe.

Three models are scheduled for 1Q/84: Prices do not include control
software ($300) or monitor ($995)

MODEL 2 -- 256K RAM,  1  floppy, PC controller, 3270 system adaptor and
BASIC 2.0 , keyboard $4,290

MODEL 4 -- All of the above but with 320 K RAM, 2 floppies, printer
adaptor for graphics printer - $5,319

MODEL 6 -- All of the above but with 320 K RAM, 1 floppy, 10- MB rigid
disk, printer adaptor for graphics printer -
$7,180.

The color monitor is 14-inch Matsushita, displaying upto 8 colors;
resolution 350 by 720.  Will only display 2K characters per screen,
regardless of window sizes.  Uses a different interface from other PC
monitors.  A black and white monitor is available, which is the same
as the PC, but with a different controller.

Keyboard is a 3278 and PC layout combination, different serial
interface.  No mouse, not even light pen.  Cursor control is through
the standard 4 key compass arrangement.

The 3270-PC can emulate a 3178, 3278, 3279 terminal

Screen management includes:

  o-User defined windows up to 2,000 characters per screen
  o-Move windows to any location on the display
  o-Alter size of windows
  o-Define foreground and background color for host sesions

Data can be copied from any window to another *except* the PC DOS
window.  One or two local notepad windows can copy or save data from
other sessions, notes, etc

An expansion module allows up a 20 MB disk to be attached plus
additional expansion slots.

The PC 3270 is a strong candidate to replace the aged (8-years) 3270
workstation family.  This gives IBM the advantage of enormous
economies of scale, with state-of-the-art hardware and maintainance
procedures.

**********

IBM PC XT 370 adds hardware and software to give the IBM PC XT the
ability to function as a System/370 workstations which can also
download and run many System/370 programs.  This is accomplished by
adding:

o-A Processor card with 3 micro processors, and a page table.  The
first micro executes most fixed point System/370 instructions; the
second emulates the remaining non-floating point System/370
instructions and general housekeeping; the third micro executes
floating point instructions

o-512 Kbytes of RAM.  This memory is separate from the PC memory in the
base system.  The PC.370 only uses this add-on memory;  the PC can
access both memory systems.

o-3277 Mod 2 device emulation card handles communications via coax cable
to a local or remote 3274 control unit.

The unit can also function as a remote 3101 terminal.  Many other VM/CMS
functions are supported including virtual memory up to 4-Mbytes.

Base price is $8995 with 10 MB disk includes monitor.

The package can be considered a combination personal computer and
desktop 370 with some limitations  This is a complex announcement with
many fine points, but the product clearly  brings enormous power to the
desktop user with its local processor and links to the IBM data
processing hardware.  This is a combination that IBM clone vendors may
find impossible to match.

**********

Other announcements include the ability to use the PC as a workstation
on the Systems 34/36/38 and 8100 products.

IBM also is filling in the gaps in its overall office integration
strategy with the following:

o-New programs exchange memos, letters docs between 8100 and 5520 and
Displaywriter,

o-Document distribution and related functions between host and for
3270 terminals.
