Hi, I'm kinda out of my head... I bought a pile of Omnibus boards from someone on eBay. Lots of boards for even more money. I got some Dataram core memory modules for pdp8/a. One 8K and three 16K modules. I expected them to be quad wide. I explicitly told the seller that I'd be interested only if they're quad wide. He sent me a photograph of a quad wide Dataram module. And what I got is hex wide. I'm going crazy... I spent all my money on that deal. In the hope to get enough core to fill my pdp8/e and /m. I'm really frustrated. Does anybody have quad wide core memory for Omnibus and wants to trade for pdp8/a memory? Examples: For one "single board" 16K module (not made by DEC) I'll give one 8K and one 16K DataRAM module. For two single board 8K modules (not made by dEC) I'll give one 16K DataRAM module and one H219 8K module. For three DEC 8K module sets, I'll give one 16K DataRAM module and 2 8K H219 modules. For four DEC 4K module sets, I'll give one 8K H219 and one 16K DataRAM module. If there are some larger amounts of 8K modules out there, I'd could throw in a set of pdp8/e CPU boards. Generally, I try to trade 3:2=8a:8e. If someone has something to trade, PLEASE contact me. I'm quite desperate because I spent all my money for the stuff. Best wishes, Philipp P.S.: I could use a single DEC 4K core board as well...

Looking for a Tally 420 tape puncher and a 424 tape reader

by wlsilva＠sbcglobal.net

Looking for a Tally 420 tape puncher and a Tally 424 tape reader, we need these for a restoration project for a Telemetry console that was used in the Titan rocket program. The Tally units that were in the operators console are missing, and we really would like to replace them for proper display. Many thanks. Walter Silva

Looking for key of IBM console

by quapla＠xs4all.nl

Ok, I have this IBM console and I'm looking for the key and possibly some replacement bulb's. The bulbs are some sort of little tubes made of clear plastic, and they contain an even smaller glass bulb. I might be able to open them up and replace them with white or yellow led with a small series resitor, but it looks like it's not that easy to do. See the pic at http://tinyurl.com/yjnt9cn Any other suggestions I could do with it? Ed -- Certified : VCP 3.x, SCSI 3.x SCSA S10, SCNA S10

Getting P4 video to work in a Sun 4/110

by derschjo＠mail.msu.edu

I've decided to play with some of my older Sun hardware this weekend, it seems :). I have a 4/110 (Sun's first desktop/side Sparc machine) and two P4 video cards -- a CG4 (501-1248) and an MG3 (501-1247). I can't get the 4/110 to see either of them. Running boot diagnostics shows it probing for a card in the P4 slot but not finding anything. I've hooked the CG4 up to a monitor and the monitor syncs with it and displays a blank screen, so it's getting power and doing something, but for some reason the machine won't see it. Any ideas? Thanks as always... Josh

Atari Disk Drives...

by geoffr＠zipcon.net

This is the way we burn the roms (now to find some MCM6810 or compatible rams and upgrade the ram in my old 1050 non double density) and make a US doubler compatible 1050. Copied the rom from my other USDblr 1050, and need to make the piggyback ram. ?course my DD 1050 needs new ram, it?s damaged too :(

S-100 IDE project

by lynchaj＠yahoo.com

Hi! My good friend John and I are working on a joint www.S100Computers.com & N8VEM <http://groups.google.com/group/n8vem> S-100 IDE project. It is based on the following design by Peter Faasse. http://www.pjrc.com/tech/8051/ide/wesley.html John built a working prototype and some software and I am making a PCB. The PCB is in trace route optimizing phase now. I can't say exactly when a PCB will be available but if you think you might be interested please let me know. PCBs will probably cost *about* $22 give or take some plus shipping. If you do want a PCB it is important you tell me beforehand so I can include it in the manufacturing order. The board will connect to regular IDE devices and includes mounting areas and interfaces for laptop (2.5" with the high density 44 pin connector) and CF adapters. John has his prototype working with a CF adapter mounted on the PCB and it seems to work fine. Thanks and have a nice day! Andrew Lynch

DEC X8 pdp8 exerciser?

by hachti＠hachti.de

Hi folks, I've heard of something called "DEC X8", a modular pdp8 exerciser. Does someone have this? I don't have it and I've been further told that it can be used to run acceptance tests on pdp8 without the need for all that little maindecs... Best wishes, Philipp
