cables

by compoobah＠valleyimplants.com

I have some cables that might be interesting to CCers: Tek ERGO cable (X-term cable with keyboard/mouse plugs on it and 3BNC) DECstation/VAXstation/[?VAX3100?] SCSI -> Cent50 cable IBM PS/2 (narrow) SCSI terminator (micro-ribbon?) Looking for DSSI ((?)VAX 4000 series -> HSD50) cable and HSD50 (microribbon) terminator smallish DG AViiON (Moto 88k) (one of the desktops or smaller tower models) No, I don't expect to trade a cable for an AViiON, but I will do partial trades or just take the free advertising (same goes for the DSSI stuff) Scott Quinn

New Finds Thanks to Networking

by marvin＠rain.org

I got a call tonight and picked up an Eagle IIe computer, Lisa 2 (3 1/2" drive), Vic 20, Bunker Ramo micro/mini with the possibility of picking up a couple of Polymorphic Toasters (the orange S-100 machine.) I will be picking up two more Bunker Ramo computers on Monday. These Bunker Ramo computers were apparently used in a brokerage house and the possibility exists that he has the docs for them. I don't have a model number right now, but is anyone familiar with Bunker-Ramo and the computers they made?

I have been looking for a Burroughs B1000 machine for maybe seven years. I missed a local one that went into surplus about a year after started collecting. I heard of another one in Ohio that I think a museum got. (The museum queried me to see if I had found one.) Other than that, I haven't heard of any. I have a bunch of Burroughs B20 workstations that I bought a couple of years ago, mostly to save from the scrap heap. Haven't been able to find any more or any software for them. (Someone is Colorado offered to send me some software, then disappeared, so, obviously, it is a conspiracy.) I also collect Sun shoebox systems (IPCs, IPXs, Classics). Since I work for Sun, I will make sure that I have software and documentation on those systems. alan

Not sure I'd want to. The normal drawings are pretty big, and lots of paper. They contain every wrire, every pin, and every connection. Also photographic layouts of PCBs. There are also flow charts and timing diagrams in there. In the service and maintenance manuals you have more descriptions, including scope shots and other kind of service information. Lots of trobule shooting information as well. So I still can't see what more documentation there could exist. But I admit that I don't have any experience of IBM hardware. I just can't imagine what more information there could be than what I have. And that was what was delivered with the machine.

I'm in search of a couple of blank 82S123s for my recently-aquired SuperElf boards. Who still carries such things? Googling on 'blank 82s123' did not turn up anything promising. Thanks, -ethan

Altair 680 switch style?

by bill＠timeguy.com

I recently bought an Altair 680 case on eBay, and am planning on trying to build some kind of 6800-based board to go in it. I'd like the front panel to be authentic-looking, and have been digging through my old Byte magazines and some web sites to try to figure out the switches they used. I've seen mostly bat-handled mini-toggles, but a few pictures have shown flattened bat-handles. I would also need to know the switch configuration (i.e. double-throw, single-throw, momentary, etc.) for the various switches. It seems like there's a lot less info around on the 680 than there is on the 8800, although I did find a pretty good article about the "new" Altair 680 in one of my "Best of Byte" volumes. Can anybody supply some switch info? Dimensions would be good; manufacturer and part number might be better. I wasn't really planning on building a 680, but I did my usual semi-annual search of eBay for the keyword "Altair" and there was this pretty (but empty) 680 case, and in a classic illustration of Pavlovian response, I clicked "bid"...
