FTGH clear-out at Mesa Electronics, Richmond, CA, USA

by classiccmp＠crash.com

Regarding the thread started by Peter Wallace of Mesa Electronics the other month - I've been by for one load, and there are still tons of DEC and HP, and a few RS6k, workstations/servers. Including a rare DECserver that has a TurboChannel Expansion box. Lots of HP 712 and 715 workstations, a C110, DECstations (MIPS) and VAXstations (derp). Please note that the vintage calculators shown are spoken for. Sorry. Mesa has to vacate these offices by the end of the month. They're super nice people, just trying to avoid anything involving a scrapper. Please dig up that thread and have another look (sorry, traveling). Link to some photos I took: https://www.flickr.com/photos/smj_crash/albums/72157683795598746 Again, location is Richmond, East SF Bay, California, USA, Earth, Sol System, Perseus Arm, etc etc. Convenient to highways and spaceports alike! Best, --Steve.

Ebay - PDP-8/M

Teletype 43

by brain＠jbrain.com

OK, go ahead and roll your eyes at me, but I was Dayton Hamvention last weekend, and there was a lonely Teletype Model 43 sitting in the flea market (on the ground, no less) for free, and so I decided I needed it in my life. I know it's not considered a "true" teletype, because it's essentially a little uC, a KB, and a little dot matrix printer, but I will wear the stigma of shame of not owning a "proper" mechanical model 33. I got home last night, and the unit fires up and works (well, in local mode. Docs claim it is rs232 out the back, but could not coax anything from my PC to it yet), though the ribbon has seen better days. I used a bit of WD-40 to free up the ink, and so things are legible now. Not sure I need help yet (did not do much debugging yet on rs232), but I see the ribbons are no longer available. Thus, I am wondering if anyone has a spare one for it, or knows of someone who can restore this ribbon (looks like it needs a new polyester ribbon and the internal foam roller looks like it will fall apart if I try to rinse it out and re-ink it) I know it's a long shot to ask, but I figure there was no harm in inquiring, and I believe making a home for a model 43 is not entirely without value. :-) Jim -- Jim Brain brain at jbrain.com www.jbrain.com

Alphaserver 4100 - Give my Monster Life!!!!

by rlloken＠telus.net

My monster lives! After being brought home in a dozen parts, cleaned with Windex and an air compressor, and reassembled, my Alphaserver 4100 is once again up and running OpenVMS. There were a couple minor snags while I went up to the attic to find a CPU fan, move a ton of stuff to find an electrical outlet, and reseated the memory modules but all that is behind me now. It is using lots of electricity and making lots of noise while displaying a Motif session in a 19" liquid crystal monitor without a stand... What could be better than this? -- Richard Loken VE6BSV : "...underneath those tuques we wear, Athabasca, Alberta Canada : our heads are naked!" ** rlloken at telus.net ** : - Arthur Black

FTGH clear-out at Mesa Electronics, Richmond, CA, USA

by shadoooo＠gmail.com

Hello, given the rules, I think the winner could be me! :) I hope it would not cost me a liver for shipment.... As I mentioned in my direct email to you, if the DECtalk business goes to the end, I would be interested also on the couple of Data General memory board, these could fit in a Nova I have here, I think. If you need address for shipping estimation to Italy, please answer to my email, or write to the address used in this newsgroup. Many thanks for your efforts! :) Andrea - DECTalk priority goes to the person who responded to my offer first. After I get shipping estimates (FedEx services only, please) should he/she decline I'll offer it to the next person to respond.

Atari ST SCSI hard drive question

by wheagy＠gmail.com

I have an Atari 1040ST that I picked up some time back. It is very clean and for the most part appears to work. It has what appears to be some kind of generic SCSI hard drive (no markings except a serial number on the back) as well as a DMA/SCSI adapter. The computer will boot to GEM/TOS with or without a floppy, but I can't seem to get the HD to do much. The HD powers up and spins/clicks like you'd expect, but after that, I get nothing on the desktop. I tried different SCSI device number settings as well as moving the SCSI plug to each of the two plugs on the drive. It did not have a SCSI terminator with it, but I picked one up...made no difference. I know very little about STs, so am learning as I go. I'm guessing that maybe there should be a driver for the HD? The machine came with software, but I don't see anything that looks like an HD driver disk. It has two slightly different language disks and will boot each of them successfully, but the HD does not show up. Is anyone familiar with this particular drive and can possibly point me in the right direction? https://imgur.com/a/pxMxl The adapter on top is a male to female adapter. Not sure what that was for. The SCSI terminator is plugged in the back below the DMA/SCSI adapter. Thanks...Win wheagy at gmail.com
