In the "golden years" of RISC workstations, the beginning of the 1990s to the early-mid 2000s (until x86 machines actually started to become somewhat usable, at least in terms of performance), it was

(I'm sorry for the very late reply, things are busy here) I have a couple of the card sets with my machines. Essentially I have a small pile of three or four 9825s that are in pretty sad shape. Jack a

Are these the same as those used on the 9825B? They look very similar. I'm in need of two switch mechanism, a "6/&" key top (top row, not numeric keypad), and a "Continue" key top for a 9825B. I think

For the 64700 in particular, I don't know. It's many boxes of stuff and we've gone through very little of it thus far. However I've made a note of this and will keep it in mind when we get to those bo

Wow, Wabtec! We just took a trip down to your facility in Wilmerding to pick up a small truckload of HP hardware that your company donated to the museum. (thanks!) We have a great deal of HP 64000 stu

I'd grab 'em for the museum in a heartbeat, but the numbers are tough to swallow these days. So in at least some cases, it's more a lack of capability than a lack of interest! -Dave

Well, that 2020s foam will be fine for a while. ;) But the best solution seems to be plastic chip tubes. They pop up on eBay frequently, sometimes in nice large batches. -Dave

#VintageHPComputers

Heh...a very successful company, yes. But fine? Far from it. For at least the past twenty years or so, they've been some of the biggest jerks in the industry. If you deal with NI or use their products

#VintageHPComputers

Right, they were never intended to be. Yes. What we're referring to here, though, is the specific type of lead frame corrosion that seems to affect TI chips, and no others. Yeah. Everyone stores their

#VintageHPComputers

That's exactly what we've seen at LSSM. I do not know the chemistry of that effect. -Dave

#VintageHPComputers

Ahhhh ok, I'm far less confused now! This one threw me for a loop since I'm only halfway through my first cup of coffee. =) At LSSM we've had some trouble with Texas Instruments chips, but most common

#VintageHPComputers

Ah ok, sorry. I'm a bit confused, I'm pretty sure National Instruments was founded in 1976 or 1977, so NI chips from the "early 1970s" would have been a pretty good trick, but perhaps I'm wrong. -Dave

#VintageHPComputers

Pretty sure you mean "Texas Instruments", not "National Instruments". -Dave

#VintageHPComputers

Thanks! Come visit! -Dave

Oh jeeze. At least check out Colin Eby's great video from last year: https://www.youtube.com/watch?v=VkjikmFRvx8 And Ken Shirriff's blog post from his visit: http://www.righto.com/2019/10/a-visit-to-l

Ahh, thank you for that. I've always wondered what that was, and it was pretty much what I'd assumed. I have a few SRM interfaces here; I've not really looked into them. Very interesting indeed. -Dave

Ooh, an opportunity for a plug! B-) LSSM is the Large Scale Systems Museum, a public museum in Pittsburgh that focuses on minicomputers, mainframes, and supercomputers. We are a "living" museum, with

Oh you've gotta be kidding me. Abstraction violation! -Dave

Oh yes, we'd love to add that to the scanning queue at LSSM. -Dave
