Looking for a TURBOchannel Extender Cable

by robert.jarratt＠ntlworld.com

I have finally fixed the PSU of my TURBOchannel Extender (https://robs-old-computers.com/2018/09/23/h7826-power-supply-repaired/). Which means that now I would like to connect it to my DECstation 5000/240. I need the relevant extender cable, which I believe to be a BC12N or a 17-03335-01. I asked on this list about a year ago if anyone has such a cable and thought I would try asking again. I have found a 100-pin SCSI cable that mechanically fits, but I don't know if that has the correct pin assignments. I am aware of a site in the UK which lists this cable (http://refurb.icc4it.co.uk/parts/legacy/dec/17-03335-01) but it looks like one of those sites that speculatively lists things without necessarily stocking them, and it is likely to charge business prices anyway. So, two questions: 1. Could the 100-pin SCSI cable do the job? 2. Anyone have a genuine cable going spare (ideally in the UK). Regards Rob

Heh. Every single time I hear the name Wang, I'm reminded of the legendary time Wang showed up at an Australian computer trade show, with their staff all wearing badges that said "WANG CARES" You have to say it with an Aussie accent and know the local idiom to understand why it's side-splittingly funny. > > No schematics, though. There's the rub. Fingers crossed Al Kossow can find that original copy. Regards, Guy

Advice requested on proper disposal of Seagate ST3000DM001 disk drives

by jnc＠mercury.lcs.mit.edu

> From: Alexandre Souza > What about a nuclear bomb? OK, if we're going to start being _really_ silly..... drop them into a singularity! :-) The best part is that you'll get to watch them being ripped apart and destroyed by tidal forces _forever_ (since time dilation means that as they go over the event horizon, their local time seems to stop compared to ours).

VCFMW

by jwest＠classiccmp.org

Once again. Silent700 put together an incredible show for the Midwest computer festival in Elk Grove. Every room that was rented was almost overflowing most of the show, so I suspect attendance was great. I heard a lot of good feedback on the speakers and presentations, and I also noticed that the auction pile was bigger than each previous year. I'm not sure which exhibit was my favorite, could be Pat's AVLVAX or Mikes HP3000 - but I also seem to have spent more time than usual at all the C64, A2+, and TRS80 machines. Maybe I'll take a detour to the 8-bitters in my collection for the near term, we'll see! In addition to the show, there were multiple parties and some late nights spent hanging out with the folks I mostly get to see once a year so friendships were renewed and such! Midwest is definitely a really fun show, I strongly encourage anyone who hasn't been to come out next year. Silent700 and helpers (mike et. Al.). thank you so much for your untiring devotion to making Midwest such a great show. J

ISO Moto Exorciser and EXORterm docs

by aek＠bitsavers.org

I spent some time this weekend documenting the hardware of these and dumping some more MDOS floppies. We had one copy of the MDOS manual which replaced the poor copy I had in bitsavers.org/components/motorola/6800/exorciser. It would be nice to find more/better docs, esp docs on the EXORterm 150 or 155. The terminal has a keytronics kb .ca 1978, of course all the foam was crumbled.

Barnett Instruments AN/URM-105C Multimeter

by charles.unix.pro＠gmail.com

I spotted a vintage multimeter in an antique shop in Startup WA for $24. Didn't have a chance to test it, but it looks in good condition under the cover. https://photos.app.goo.gl/sTQF8g7jXx2TMKqCA If someone wants it, I would be happy to acquire and ship it at cost. -- Charles

Manual for Documation TM200 punched card reader

by guykd＠optusnet.com.au

Thanks for the link. So far I'd only tried google, assuming anything relevant on bitsavers would show up. It didn't, which is interesting. My search was only very brief though. I'd been doing an initial eval on the reader in the evening, then read the post about Mr Hollerith's house. So hadn't yet done any serious searching. The unit was made in April 1977. Someone else mentions the TM200 is not the same as the M200, so I have some reading to do.

SMD disk needed

by dseagrav＠lunar-tokyo.net

Does anyone within driving distance of central Illinois have a SMD drive I can borrow for awhile until I can get some kind of SMD emulator working? Anything 450 MB or bigger will do. I need one for the Lambda.

Fall cleaning - 9-track drives available

by guykd＠optusnet.com.au

Too far? Road trip? I'm crying here (Sydney Australia.) I have a couple of HP 7970B's (and the sevice manual) though not yet running. But I have no 1600 bpi drives. Oh well...
