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. -- -tony ard12(a)eng.cam.ac.uk The gates in my computer are AND,OR and NOT, not Bill

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. Isaac Davis idavis(a)comland.com indavis(a)juno.com

Regular Posting: Mail Basics

by bill＠booster.bothell.washington.edu

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 ;).

stuff for trade

It's allegedly in a book called _Upgrading and > Repairing PCs_, but I don't know the author. > 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! Marc -- >> ANIME SENSHI << Marc D.

Gas plasma displays

by ds_spenc＠alcor.concordia.ca

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? Doug Spence ds_spenc(a)alcor.concordia.ca

Kaypro 4

by David_A._Vandenbroucke＠hud.gov

>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? 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). --Dav david_a._vandenbroucke(a)hud.gov
