MSX was a "standard" that allowed machines to share mostly BASIC source code, it was popular in Europe for about 3 tears then died. I don't know the involvement of MS in that atempted "standard" but since it was crappy from the start I would believe they originated it ;). I think it was followed by MSX2, it was enhanced to keep up with the increase in computing power. >So many Z-80 CP/M machines... were they compatible, to a reasonable >extent?

BBC Model B - video help

by adavie＠mad.scientist.com

This sounds about right. If I counted the number of characters before the repeat, couldn't I then identify the stuck line? Then, perhaps... I could go to the hardware? Am I making sense?

RCA CDP 1802 & SC/MP parts

by jmg＠iac.net

Hey! I just landed pieces to an 1802 kit! I've got everything but the hex keypoad and power supply (though I'm sure +12, +5, -5 would do the trick). This is not one of those single board computers like the ELF-II, it's made up of several boards which connect to the main unit via ribbon cables. Here are descriptions of the boards: Primary board with 1802 labled "Infinite" Part Number UCE100001 dated 1976 This board has a rather large crystal which appears to run at 135khz (if I'm reading the markings right). A large blue 3000 MFD capacitor, some smaller disk .01 uf capacitors, and these chips: 4) RCA 701 CD4001AE 1) RCA 631 4049AE 2) 2606B (I think this is the 256 bytes of RAM) The board also has a two sided 36 connector per side edge card, which connects to nothing. Next to the 1802 is a red ribbon cable which attaches to another board containing four LED readouts and a singfle LED light (attached to the Q bit I suppose). Each LED (but the Q light) has F9368DC 7705 - one for each LED). The second board is listed as INFINITE 1976, UCE30004. On an unattached board are two LED's, four chips and a 24 pin socket (empty - I guess for a monitor ROM). This chips are: 2) RCA 701 CD4001AE 1) M1-0110-5 (7649) 1) MC14013CP (7438) The last unattached board contains three switches and three buttons, with a metal faceplate labeled UC 1800. The buttons are labeled Reset, Start/EF1, and Enter, the switched are labeled ON/OFF, STNDBY Power, and Load Mode. This board also has four chips: 3) MC14013CP (7438) 1) RCA 636 CD4011AE Both of the unattached boards connect to the primary board via a ribbon cable terminated by a 14 pin DIP; there are two 14 pin DIP sockets on the primary board. It's unclear which board should be plugged into which socket. I also snagged pices to an SC/MP kit, along with a bunch of DOCS and old COMPUTE newsletters dating from 1978 or so (WOW!). Also got a COSMAC Microprocessor Product Guide (think I could call up RCA and order any of the things listed therein????? - HA!), and an original RCA 1800 Users manual (WOW!), in almost pristine condition. As a kid I put together an ELF-II in 1980 (I was 12), so I have some familiararity with this line of processors (could never get over the gethi instruction yuck yuck yuck). Looks like I need to put together a hex keypad and P/S to get this up and running. Anyone have any ideas? Also, this things is missing the CDP 1861 video driver which my old ELF-II used to have - what's up with this? I wonder what happened to all those old late 70's kit manufacturers... I don't see any FAQs out on the net for those old ELF's, KIMS, SYMS, and AIMS. Oh well, relpies by the curious and knowledgeable would be most appriciated. Thanks! J. Maynard Gelinas

I got some more stuff! :-)

by rexstout＠ptld.uswest.net

Well, at the hamfest yesterday I got a VT220 terminal, an HP-IL/HP-IB converter(maybe now I can use my HP 2225B...), a Laser 128 with two monitors(broken Zenith and working Apple Monitor III) two disk drives(Apple Disk II and a clone) a box of Apple II cards(mostly printer cards), a Hayes Micromodem II(110/300bps switchable, Apple II card and a box that sits outside the computer), two huge 9600bps leased line modems(kinda useless, but they were free!), an IBM 3180 terminal keyboard(but no terminal...), and of course I couldn't leave without getting a battery for my TH-205 radio. Everything seems to work except the VT220 keyboard and the Zenith monitor, and I have no way of testing the modems but they ligth up when plugged in, and I'm hoping that the 3180 keyboard will work with my 3191... -JR http://members.tripod.com/~jrollins/index.html - Computers http://www.geocities.com/Area51/Lair/1681/ - Star Trek

Tandy/Radio Shack Model 12

by gpine＠popmail.mcs.net

I have a non-working Radio Shack Model 12 computer, some software, and some documentation that I would gladly give to someone who could use them. I don't think that the unit would be worth the cost of shipping as the computer is probably useful only for parts for someone who has one already. I know that one disk drive (it has two 8-inch drives) is bad. It was physically ruining diskettes by scraping off the coating in a ring toward the center of the diskette. In the process of inspecting the unit to check out the drives, I managed to break off a nub of glass near the CRT socket and the vacuum seal was broken. If someone wanted to fix this unit, he would need one good 8-inch, half height drive and a new CRT. So far as I know it has one good drive, a good motherboard, power supply, keyboard, and whatever other electronic boards as might exist (I don't remember). The computer was working at the time I finished it off mechanically except for the bad disk drive. I also have the Model 12 Owner's Manual and TRSDOS-II Reference Manual, a brand new copy of TRSDOS 2.0B Version 02.0B.00 from Radio Shack special orders dept., a copy of Pickles and Trout CP/M for the Model 12, and a copy of SuperCalc 2 with P&T CP/M. I also have a plastic dust cover for the Model 12. I live in the Chicago area. If anyone is interested in picking up the unit, send me an email, and we'll make arrangements. If someone wants the unit enough to pay the cost of packing and shipping via Mailboxes Etc., I'll check into costs, but I doubt that it would be a good investment. Let me know of any interest.

There were a few more flavors as well used in combination with instruments like the 2105A. Regards, Don
