It feels SOOOO good to run a modern OS on classic computers

You could just run OpenVMS V7.3 on that MicroVAX :^) Well, yes... how about I meet you halfway and just say that OpenBSD is on my one RZ26 drive and VMS v5.5-2 is on the other internal drive. So I get the best of both worlds :-) Thomas Dzubin ps: will OpenVMS 7.3 run in 8MB of RAM? (yeah, yeah, I know...google is my friend)

11/44 is alive, as is the 11/34!

by jwest＠ezwind.net

The 11/44 has come to life. It passed all the diags I threw at it, plus booted RT11. I did that on an RL02 and would like to switch that system to an RA81. Once the RA81 is in place, that system is done. But at least the cpu is known working. In case I didn't mention it here, the 11/34 is also alive. Turns out the "odd" diagnostic results I was seeing are actually what a working system prints. The /34 booted RT11 as well and ran a few small compiles. All I have to do now is move the cpu from the table on the side of the rack and mount it inside the rack. Then that box is done as well. Once those above cosmetic issues are done, I'll take a short break and then revisit the 11/45 project which was temporarily shelved :D I'd love to spend more time now with the /44 and /34 to get TSX up and running, play with sysgening a new system, etc. But no time to play yet, I'm under orders to consolidate and get rid of stuff. Thanks to all who gave input, advice, and knowledge! Jay West

RA81 destruction

by jwest＠classiccmp.org

I'm not one that ever advocates tearing apart classic gear. But in this case I think it's warranted and I'd like some advice. I have more than a few RA81's that are all clearly labled "BAD HDA", and the person I got them from confirmed "these are all dead". I grabbed them anyways as they had to be taken as part of "the deal". I am not familiar with these drives at all. From what I've heard over the years, they have a fairly high failure rate and thus people who use them are often looking for HDA assemblies. This makes me think that it's unlikely that I'll be able to just pull the bad HDA's out and obtain good ones to put in. Plus I don't need this many drives at all, so I think it's time to tear them apart and scrap them. Since I don't know anything about RA81's yet (have never used them or opened one up), and because I do intend to keep one or two of the drives running (a few don't say "bad hda" on them), can someone tell me what parts I should scavange off the dead ones that are worth keeping as spares? I know the obvious like the light bulbs and drive select plugs, but what about components on the inside that "those in the know" would advise I not just pitch with the drives? Lastly, are the casings for the RA81's mostly steel, or aluminum? I'm pondering putting them in the van and taking to a scrap metal dealer. I wouldn't do this, but they are clearly dead, HDA's not likely to appear, no one wants them, and I need the space. Jay West

PolyPaks (was Re: OT: Where have electronics hobby stores gone?)

Was pretty amazing stuff back then. I grew up in Wakefield Massachusetts. I used to ride my bike over to PolyPaks and raid their dumpster on a regular basis. It looks like they used to get all sorts of stuff for evaluation that they'd toss. Sometimes I'd have money to spend there too.

11/44 memory question

by jwest＠classiccmp.org

It would appear that the slots designated "MEMORY" in the 11/44 (slots 9-12 in the *system* backplane) are actually "Extended Unibus" slots. My reading is that these slots allow 22 bits of memory addressing instead of 18. So, of they are still "unibus" slots, does that mean that if there is one board in slot 9, that slots 10-12 should have grant continuity cards (G727)? If they are unibus slots I would certainly think so, but they are designated for memory only... and I can't find any reference to using grant cards there for non-populated memory slots. Anyone know off the top of their head? Jay
