Anyone interested in IBM PC/RT gear? (located in PA USA)

by bli＠psu.edu

I wasn't sure if there might be any parties on the list who would be interested in old (late 80s/early 90s) vintage IBM PC/RT gear. Also of potential interest to collectors of the later PowerPC gear as this was the predecessor. I have several items that may be of interest to hobbyist/collectors and I really do not have the space for them but also have no desire to see things end up in the dump if they can find a good home. Any interest at all? I do not have a current inventory but I know I have ... a couple PC/RT 6150 server towers (worked after Y2K, haven't run them much since) a couple PC/RT 6152 minitowers (based on a PS/2 Mod 60 w/ add-on RISC cpu card, think I have one or two that work & another "shell" for parts) a pair of streaming tape drives (one working, one I don't remember trying recently) various monitors, keyboards, mice, tablets, & cards and so forth (some working, some may need repair) documentation/software binders for AIX and AOS (BSD) ... if anyone is interested, I can get you an inventory in a few days' time with more details. I would be looking for someone to take the whole lot I think, rather than unload some things & still be faced with the prospect of sending these off to the dump for lack of space anyway. And ideally someone who would try to get the old parts back into a functional state or as a "museum piece" or something like that rather than melting it down for gold. Not looking for any money, my monetary investment was paid off by several good years of use over a decade ago. Definitely a "come and get it" as these are old, heavy and I doubt that they'd be worth while to ship. If you are at all interested, let me know -- Thanks! -j Jeff Brendle Office: 243 Deike/(814)865-3257/fax 865-3191 Desktop Support Spv.

HP disk power unit

by wdonzelli＠gmail.com

Today I scored an obscene collection of TTL and ECL chips, in a weird sight unseen sale (the guy was selling the parts drawers as drawers, and would NOT let buyers see what parts were inside!), but that is not the point of this post. Well, maybe I am yanking the chains of all those people that say TTL and ECL is getting hard to find. ANYWAY... Also scored was a power unit to an HP 7900A disk - the 14 inch unit >from the 2100A and friends. Very nice condition, and heavy as sin. I do not need it, but it was sitting there so forgotten and lonely. Does anyone need one of these supplies? Very nice condition. I forget the HP number - 13mumblefooA. I really do not want to ship it, but could deliver it to MIT or any of the other area hamfests. -- Will, in 10512

Unibus Framebuffer information needed (DDS)

by ball.of.john＠gmail.com

By luck I stumbled across what may or may not be a complete hex-width Unibus framebuffer board set made by Dynamic Digital Displays. Now that would be cool in the PDP-11/84. :) I can identify three of the boards but not all of them: -FB1000FBL001 Serial 55 Rev. 2 (looks to be the main memory as well as the D/A logic to output to RGB) -1000VB-001 Serial 35 (calls itself the "Voxel Buffer") -1000CTD001 Serial 47 (calls itself the "CTU Board") These boards can be seen at the following link: http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_206… Then there were two other boards that the seller had as well. They may be related to the previous three and they also might not be. -1000HIL001 Serial 45 (board calls itself "HI") - http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_206… -1000DTD001 Serial 54 (calls itself "DOTS") - http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_206… Unlike the first three boards, these ones have "Dynamic Digital Displays" on them, however the model numbers are similar on their structure. The unfortunate part is that these boards have connectors on them ("HI" board has three 40-pin ribbon cable headers, "DOTS" has two 50-pin ribbon cable headers) so either I'm missing more boards that that talked through their own bus and not the Unibus, these connectors are for options, or there is additional hardware/cards I am missing. I have no way to read the two TMS27C512 EPROM chips and Google has pretty much nothing about these boards that I can locate and their hand written serial numbers mean these are something special. Might anyone have further information on this?

Microprocessor simulators

by CCTECH＠beyondthepale.ie

A while back, there was a brief discussion on the list about microprocessor simulators running on larger systems. Some interest was expressed in the simulators I was involved with some years ago. I've put together some details and some code here: Z80 simulator in FORTRAN IV for the MUSIC/SP IBM mainframe operating system http://software.beyondthepale.ie/music/z80/ 6502 / BBC Microcomputer simulator in FORTRAN and 370 assembly for MUSIC/SP http://software.beyondthepale.ie/music/y6502/ 6502 / BBC Microcomputer simulator in FORTRAN and VAX assembly for VAX/VMS http://software.beyondthepale.ie/vms/y6502/ All the bits and pieces are provided to run the first two simulators on the freely available "MUSIC/SP Demo system" running on Sim390 or Hercules and the latter one on any reasonable VAX/VMS platform or simulator. The original unmodified code is also there. With the addition of a BBC Micro BASIC ROM, it is possible to run text based BASIC programs such as http://software.beyondthepale.ie/bbcmicro/survival/ (an adventure game) on the latter two simulators. Regards, Peter Coghlan.

available M9404 / M9405

by quapla＠xs4all.nl

Found during sorting out some boxes, a M9404 (Q22 cable connector) and a M9405 (Q22 cable connector mirror image). Both are in good nick (no broken of latches) and each card has 2 50pin berg connector sockets on them. I would like to get Eur 20 + postage for it. I'm in the Netherlands btw. -- Dit is een HTML vrije email / This is an HTML free email.
