Yes, this tallies with my current config, 1-_-1-_-_-1-_-1. So I have to
add all four SIMMs in one go then? I was asking because I have seen some
"sealed" kits on eBay too, although the last one I saw was for only two
16MB SIMMs, so I wasn't sure what I needed. I guess therefore I'd have
to score another pair from somewhere before they'd be useful. Thanks for
clearing that up. They were going for about $15 for 2x 16MB, which
wasn't too bad, I skipped 'em 'cos the machine wasn't working, but
now...

Yes, this isn't quite up to speed as my other DEC, (a 256MB 3000/600),
but it's quick enough to be useful somehow. And the great thing is both
machines are almost near-silent. The hard drive is definetly the loudest
part of the machine, the PSU fans are neglible. Oh, and you can
dismantle the thing without a screwdriver... :-)

Here's hoping...

It also complains about the gfx card, (possibly because there's no
monitor hooked up), short of removing the card, can I at least stop the
VAX complaining about it? There's an SRM var on the DEC 3000 to do
that.
