I found a box of these boards at a scrap place. I have ten boards, two backplanes, and a bus extender. I don't exactly know what these are, however. The connectors are "eurocard" style (I think that's what they are called), they look similar to Macintosh NUBUS connectors. I don't really know much about them other than what components are on the boards. The boards: http://24.194.65.231/images/gespac_boards.jpg CPU board: GESMPU-4B It uses a Motorola MC68000FN8, some PLA's, two 27128's, and a 1488/1486 driver pair. It has a twenty pin IDC header on the edge of it, and two pushbuttons, one red and one black. It also has a five pin header, and two LED's. http://24.194.65.231/images/gespac_cpu.jpg Parallel board: GESPIA-2A It has two MC6821P's on it, and two twenty six pin IDC headers on the edge. http://24.194.65.231/images/gespac_pia.jpg Serial board: GESSIO-1E It has two 6850's. It also has two sockets for a 1488/1489 driver pair, but the chips are missing, with a post-it in the package, with "MC1488P MC1489P" written on it, as if someone borrowed the chips, and left a note. There are two twenty pin headers on the edge. http://24.194.65.231/images/gespac_serial.jpg INC board (whatever that is...): GESINC-1 A bunch of TTL logic, some PLA's, a 34 pin IDC header, a ten pin IDC header, and another one of those five pin headers like on the CPU board. http://24.194.65.231/images/gespac_inc.jpg RAM board: GESRAM-4B 18 TMS4256-12NL DRAMs and a bunch of logic chips. http://24.194.65.231/images/gespac_ram.jpg I also have a bus extender card. It's just a board with a connector on both ends, and a jumper block to select which signals are connected. http://24.194.65.231/images/gespac_extender.jpg Anyone know what these boards are for? What kind of a computer might these have come from? I probably have enough parts to create a working computer, but I'll need to figure out how to connect a storage device, and find some bootable media. Two of the three CPU cards have two NVRAM chips on them, the other one has two ROM chips in it's place, so I'm worried that the NVRAM might have become slightly more V over time, so I don't know if I could get them to work. I have three CPU boards, two parallel boards, two serial boards, two INC boards, and one RAM board. I also have two backplanes and the bus extender. The backplanes are labeled with the proper voltages, so powering it shouldn't be a problem, the problem will be figuring out what the pinouts of the serial ports are, etc. Any ideas? Thanks!

IBM Displaywriter

Are you still looking for an IBM Displaywriter to purchase. I have a working one that I have kept in case I needed data stored on disks, but which I would now like to get rid of.

Server flood soon

I just built a new (by new I mean new use for an old box) WINS NT4 server box. Next year is the Active Directory conversion project, God save us all. This year, I did the migrating from Novell 4.11 to Windows 2000 (in an NT4 domain) project. I'd rather have migrated it all to Novell 6, but, believe it or not, Microsoft was cheaper.... ...of course, if I *really* had my way, I'd convert all the Windows servers to Samba 3.0 I can dream, right?

Server flood soon

by Edward.Tillman＠valero.com

By the time this happens, I'll hav switched my home network to LindowsOS. I'm already tired of the Microshaft - Intel straightjacket monopoly, and will be quite concerned for the networking world (including the internet), when their vaunted "M03" technology is fully deployed. I've already drifted my hardware away from Intel, and am currently seeking applications to run under a Linux environment. Its not a hard thing to do, and if enough of us do it, maybe Microshaft will finally learn some lessons. "Upgrade" or evacuate? Your call... Go AMD! Go DDR! Go LindowsOS! Cheers...

Cromemco C-10

by ejchapel＠comcast.net

I have a Cromemco C-10 that works great. Dual floppy drives and the SP software package are there as well. The item I would like to add is the pedestal for the monitor. It is made of dark brown plastic. Cromemco touted it in the early '80s as 'ergonomic' before the word was cool. Anyone know of a Cromemco resource where I might find the pedestal? Ed Vancouver, WA

The CFX-40 starred in a Movie!

by scottmueller＠compuserve.com

Did you know that our beloved CFX-40 had a starring role in a movie?! Either did I, until I was channel surfing the other day, and lo and behold there it was, shown in glorious full-screen detail no less! The CFX-40 actually seems to have quite a pivotal role, it appears in several scenes throughout (including the opening scene), but is featured most predominantly in one scene where it is used to help captive warriors escape >from the clutches of an evil king and his barbarian henchmen. You read that right, in this movie, a CFX-40 is clearly being worn by what appears to be a primitive warrior wielding a sword. <g> The watch is even shown close-up as he uses it to reflect the sun into the evil king's eyes, blinding him. In the confusion the king is stabbed to death by a bikini clad warrior princess, initiating a fight by which the warriors escape. OK, enough suspense: The movie is "Gor" <http://www.imdb.com/title/tt0095241>, which was produced in 1987, based on the 1966 book "Tarnsman of Gor" by John Norman (a pseudonym for Professor John Lange) <http://www.amazon.com/exec/obidos/ASIN/0759200548>. I never read the book, but I don't believe the watch is featured there. <g> Beware, this movie is probably one of the worst you'll ever see, even by MST3K standards <http://www.mst3k.com>. However it does feature warrior women in leather bikinis <g>, and if you're a fan of the CFX-40, I'd say it's a "must-see". Scott. PS: There is apparently a sequel called "Outlaw of Gor", but I haven't seen it and don't know if the CFX-40 appears in that one as well.

Hi There are a number of similar things between the 6530 and 6532, other than the ROM in the 6530. Still, you can't just replace all 6530's with a EPROM and a 6532 because some of the level inversions and address selects are mask selected in the 6530. I've not looked into the one on the kim but for those that have blown 6530's, one may still be able to make a board using a 6532/EPROM and a little glue logic. I have a Gottlieb pinball machine that this is not as easy to do because of signal inversions.

ZN448E

by andrew＠leadic.com

Hello Tony, I am having a little problem finding info for this part and I found you comment on the internet that you have the databook. I am doing a small repair that calls out for ZN448E-8 but I only found info on ZN448E. Are these the same part? Any information is much appreciated. Regards, Andrew
