Project seems to have stalled, in that I don't see comments at Hackaday or RetroBrew since mid-February -- but Andrew kindly posted schematics, Gerbers, etc on Hackaday.

I've got an Innoventions SIMCHECK RAM tester, part number INN-8448. It tests 30 pin SIMMs and SIPPs, with adapters available for DIP chips and 72 pin SIMMs. Works great. The unit I have didn't come with the 72 pin adapter unit, I bought that separately. While I've seen these parts used...

ISTR a thread I posted in here covering this model, but all I could find was this one. :unsure: This was a very nice machine, when I needed a Windows box at work in the mid-90s and found one of these unused in a corner. Much more in the vein of a workstation of that era than a typical PC. I...

Funny, I was about to mention a console issue. Sadly, I don't have the default Tek 4105 terminal for the console. And despite having what appears to be a well-stocked /etc/termcap file, I have had to set my VT510 to Televideo 925 emulation and set my terminal type to tvi925 during login in order...

I landed a Tektronix 6130 earlier this year, one of a few NS32000-based workstations Tektronix offered in the 1980s. I was very surprised and pleased to discover that it was able to boot from the ancient Micropolis 1302 hard drive inside. No expansion cards, and the UTek installation has been...

Not sure, to be honest. I had received a complete unit "untested," which wouldn't power up. I got an additional PSU, made no difference. Got another system board (still R5k), still wouldn't power up. Set it aside for a year plus. A couple weeks ago I missed out on a trade for a different...

Typically, they look for a place where they can ask what they can do with them now that they're running. 😉 This may happen before or after spending a lot of time searching with various combinations of keywords, trying to find any hardware or software for them. I'm in this stage regarding a...

Pete shutting down Nekochan was a gut punch, and I didn't need the drama around the replacement(s). The quality of the former only made the latter less attractive. But glad to see some handles I recognize in this thread, and run into some folks recently at VCF West. I spent a lot of time...

Still have two here, with known-bad hard drives. One (HDD present) boots up from the Diagnostics floppy but has a memory issue to be tracked down; the other (HDD removed) won't boot from the floppy at the moment. Trying to decide whether or not to use them for an exhibit at VCF West... Still...

Yes, this was an unpleasant discovery a few months ago. But it's better than the drippy goo that certain grey rubber feet have turned into over a similar timespan...

Recently landed an Opus Systems 110PM ISA card, the NS32032 version - but it did not come with a memory daughtercard. So, if anybody happens to have an extra 1MB (Opus321) or 3MB (Opus323) card, I'm an interested buyer.

I'd have the same first instinct, but there are a lot of reasons why a corporate entity might change. Bankruptcy, reorganizing (LLC vs. "C" corp), spinning off something or being spun off, etc. I don't know how likely those are to have happened in this case, and I don't know if any of them would...

None taken, and at the risk of wasting even more bandwidth and time -- Timo's right, it is actually against the rules. I had checked the pinned "New Buyers and Sellers" post beforehand as I'm not a frequent flyer here, but not the "updated Terms and Rules" sticky at the top of every page. It...

Oh my. DM sent.

The PDT-11/150 is a perfectly cromulent PC. Was it ever sold without the second floppy drive? I can't remember if the case was setup to (theoretically) allow for that or not...
