Oops... wrong key... I have an SC21 on the way (as I mentioned elsewhere). I have some 10" and 14" SMD drives I could steal from an SI9900, but I'd like to find some lower-power drives to play with - I'm thinking 2BSD on a Unibus PDP-11, so anything from a couple-hundred megs and up would be great. Are there any non-SMD-E drives in the the 5.25" size? Would anyone know where I could pick up a couple? I remember there were SMD drives up to 600MB in that size, but I don't have part numbers and I don't remember the exact interface type (I just remember the ads on Usenet where the seller was warning people that these 600MB-for-$600 drives would *not* work on your PC). Thanks for any help locating some smallish SMD hardware, -ethan

Trying to help a new VAX-11/750 owner

by erd_6502＠yahoo.com

A friend of mine at work got the 11/750 recently offered for free in Pittsburg. I don't yet know how it's loaded except for the L0022 mem controller and 14MB of RAM. My friend would _like_ to get a CI750 for it, since he already has an HSJ40 at home. Barring that, he's considering the $$$ for a Unibus SCSI controller. Besides the actual L0009 card, I'm reading that there appears to be an external enclosure to house part of the CI750. My 750s were always a local-disk affairs (UDA50/SI9900/etc). I have no experience with CI hardware and don't know what advice to give him. Can anyone here describe what you need to pull this all together (he already has an SC008 and cables). I'll try to get him on the list... he currently has about a dozen Alpha Servers and is in the process of working backward in time in the DEC world. -ethan

Systems Industries CS-1?

by erd_6502＠yahoo.com

I have this dual-height Qbus card that I was told was a SCSI card (got it from a former boss). It has a 50-pin connector and gives the appearance of being a SCSI card, but I can't find any docs on it online. The logo reminds me of Systems Industries', and the model number appears to be "CS-1". I checked with Al's site and there's no SI docs there at all. There's a good chance that this is a TMSCP device, not an MSCP device, but I don't know that for sure. Is this board familar to anyone? -ethan

Fwd: Monrobot XI details

by dbetz＠xlisper.mv.com

Here is the latest information on the Monrobot XI computers that have become available in Virginia. I'm afraid that while I am quite interested in these, I will probably be unable to acquire one. It seems they are interested in selling them rather than giving them away to good homes. Any reasonable sale price in addition to the considerable cost of shipping a 500 pound machine will probably put them out of my price range. I'm hoping that some public computer collection will acquire at least one of these and make it available for viewing. I would be happy to help in the rescue if anyone here decides to buy one. I would even consider contributing to the purchase and transportation of a machine if it ends up in a publicly accessible museum or collection.

by anheier＠owt.com

I have a bunch of older National Instrument data acquisition cards available. Best offer or trade for older CPU processors. NB-GPIB, macintosh Nubus GPIB card AT-AO-6/10, ISA bus analog output card PC-TIO-10, ISA bus timer/counter card. I have manuals, cables, and signal breakouts for some of these. thanks Norm
