Does anyone on this list know anything about a machine I've just rescued?
It claims to be a 'Computer Automation' Naked Mini, and mine appears
(alas) to be incomplete
I have the 4U rack case, the backplane, frontpanel (which seems to use
membrane switches and LEDs), CPU board (At least I assume that's what it
is - it's got some 74x181 ALU chips on it) and 2 core memory boards.
The PSU is missing, but even so I think it was worth saving. I guess I
can hack something together.
I have no docs on this at all, so any info would be welcome. I don't fancy
working it all out my own.
Talking of docs, does anyone have a copy of the I/O reference manual (or
whatever the title is) for the HP9100 calculator? This manual was written
for people who wanted to interface non-HP peripherals to the HP9100 (HP's
first ever calculator), and contains hardware info on the connector on the
back of that machine - info that's not in the operation/programming
manual.
I'd be interested in any info on that I/O port - I want to try a few
things.

The gates in my computer are AND,OR and NOT, not Bill
I have a RS TRS-80 5 Meg external hard drive on the auction at Ebay.
It's in good physical condition but I don't know the working condition.
Someone pulled one of the interface cables out. There is a picture and a
little more info in the listing. Only going for $20 so far. Auction ends
Thursday 1:15 PM.

Hello,
I will visit Los Angeles over the Memorial Day weekend. Are there any good
thrift shops in the area? Thanks.

A true hacker. Why go waste all that money on a pre-assembled Sidewinder
missile when you can just go get all of the parts and put it together
yourself. Plus, the pride you will feel when your baby takes off and blows
something up. There's nothing like it.

ClassicCmp Regular Posting
Mailing Lists and How to Talk to the List Robot
Last Rev: 5/2/97
This message is posted with frequency proportional to
subscription rate (or monthly).
Point of contact: Bill Whitson (bcw(a)u.washington.edu)
Mailing List Basics
A mailing list is a simple device which takes an e-mail and
redistributes it to a group of people. People can add and
remove themselves from the distribution list by Subscribing
and Unsubscribing. When you send a message to the list, it
is first examined by the robot for key words that tell it
to process an automatic funtion (like help, subscribe,
unsubscribe, etc). If the message does not contain a keyword
it is sent to the distribution list.
How to Talk to the Robot
There are a few List Processor commands that you might want to
use. To send a command to the list processor, write a message
to listproc(a)u.washington.edu (Do NOT send the message to
classiccmp(a)u.washington.edu). In the body of the message (not
the subject line, that is) write one of the following commands,
then send the message.
SET CLASSICCMP MAIL ACK
Tells the robot to send you a copy of messages you
write to the list. This is the default.
SET CLASSICCMP MAIL NOACK
Tells the robot NOT to send you a copy of messages
you write to the list. I don't recommend this.
SET CLASSICCMP MAIL DIGEST
Tells the robot to send you a digest of messages
rather than each as it is posted. With this option
you will get a weekly bundle of messages and keep
a nice, tidy in-box.
SUBSCRIBE CLASSICCMP Your.Address
Subscribes you to the list.
UNSUBSCRIBE CLASSICCMP Your.Address
Removes you from the list.
That's the basics. If you need to know more just drop me
a line at bcw(a)u.washington.edu. Some requests may take a
couple days as I just don't know that much about the list
processor ;).

I have that book. It's by Scott Mueller and the one I have is 1988.
Here's what it says (to add to your info):
"...All this hardware is run by a program called the 3270 PC Control
Program. This combination can support up to seven concurrent
activities: one local PC DOS session, four remote mainfram sessions,
and two local electronic notepads. With the assistance of the 3270
PC Control Program, information can be copied between windows,
except that a PC DOS window may not receive information. "
The cards used are:
3270 System Adapter (communication 'tween the 3270 PC & 3274)
Display Adapter (replaces PC's mono/cga card. No graphics unless...)
Extended Graphics Adapter - XGA (required to get graphics)
Programmed Symbols adapter (provides graphics with 3278/3279 stations)
IBM also had an XT 370 that used the PC 370-P, PC 370-M, and
PC 3277-EM cards.
The P card emulates the 370 instruction set. This card has the
Motorola 68K cpu's. It also has the 8087.
The M card is the 512K mentioned above.
And the 3277 card hooks up to the S/370 mainframe.
So I reckon you have the XT 370.
The price of the 370 attachments was $3,000 over the price of the
XT this stuff had to go into. Jeez!

Greetings.
Recently I picked up a manual for a machine called the "Laser Concept
286/16 Laptop" for the sole reason that it has a couple of good photos of
the machine's red gas plasma display.
I remember seeing some other systems with this kind of display in
magazines. (The GRiD Compass comes to mind?)
Anyway, I'm wondering why this technology was so little used. What were
the major disadvantages? And do these displays still survive today? (Does
anyone have one?)
I think gas plasma displays look extremely cool, but I've never actually
seen one in real life. They could be a real pain in the eyes to use for
extended periods?

Gee. One I can answer. I'm not a collector like you folks, but I did use
Kaypros and other CP/M machines for about a decade. The Kaypro 4 is your
basic Kaypro transportable with a Z80 CPU (probably 4 MHz) and 64K RAM. It
has two DSDD floppies which give 390K each in Kaypro's format, which is where
the "4" comes from. At some point in 1984 or later, Kaypro switched from
using Roman to Arabic numerals. Thus the 4, as opposed to the IV, is a later
machine. Some of the later machines had a built in 300 bps modem, but if
memory serves those all had "X" suffixes, as in Kaypro 2X (which
paradoxically also had DSDD floppies, not the SSDDs of the Kaypro II).

Hi,
I have a few old computers at home up and running, but without
documentation. Does someone has information about the following systems or
can point me to a source of information (servers, books, software) ?
Vendor: System: Operating System:
Wang OIS 140/III OIS 9.9
Nixdorf 8870 Niros
DEC uVAX II netBSD
Epson HX-20 Basic
Hitachi 6805 developing system
The uVAX is common, but Informations about the Wang and Nixdorf are hard to
find.
Thanks for any help,
-- Karlheinz
Anyone ever heard of a Kaypro 4? I know what the Kaypro is, but this
specific model? When was it released and what does it run? What type of
CPU does it have?
