[rescue] RE: VSIMMs in an SS/20...

I don't think yo can run 3x VSIMMs in an SS/20 - I thought only two were supported (one using the built-in 13w3 connector, the other requiring an aux video board)...

I suspect you have two VSIMMs and maybe a prestoserve card - that or a system admin lost his mind and started stuffing stuff into the SS/20 without regard for functionality...

Either way, great find! I just got two additional 4 Meg VSIMMs and aux video cards for my two SS/20s, which I may wind-up selling if my Ultra 30 deal comes through...

Pity, they are such nice SS/20s too 2x SM71s, soon to have dual 4 Meg VSIMMs, etc... But the Ultra 30s are, um, nicer!

Yes. I've just got this habit of not wanting to wipe drives that have my
data on them. I've still got an OS/2 drive around here somewhere. I
think I thought I would boot it again someday. Still got a Slackware
linux drive with a .9something kernel too.

Yep. Solved it, though. I went to meet a new client for a project, and
they'd just gotten rid of a bunch of SPARCs (on ebay, could be some of
them ended up here). A bunch of parts laying around, and I asked if they
had a framebuffer left. The guy said probably, let's go look in storage.
So we went. Turns out there's a Sparcstation 20 sitting all by itself.
He said it didn't boot, but if what I needed was in there, I could have

I didn't even try booting it. Ripped the RAM out (2x16, 1x32 3(!)x4M
VSIMMS) and swapped the system boards. Now it works like a charm. And I
got three 4M VSIMMS, and an extra 32M RAM in the deal.

Question. This thing had a small framebuffer that plugs in to the little
white header on the right side of the board, taking up the bottom SBUS
space. What is it for? Just so I can run a dual headed system? Shame I
don't have a second Sun monitor

So Solaris 8 is installing right now. Woo-hoo!

So, with the VSIMMS, I assume this thing willspeed up a bit and maybe be
worth keeping on the desktop? Or is it better off on the rack?

Even with 8M of VSIMMS? Or is that the price you meant I wouldn't enjoy?
I see these things go for ~$75 on ebay.
