Actually, if you run unix on the vaxen, then you probably could use it for
the serial consoles, printer, camera and palm.  I don't have any vaxen,
and I don't keep my extra unix machines on all the time, so I'd have to
wait for a SS2 to boot if I wanted to use's it's two serial ports, which
is further cut down since one of those two is used as the console.

Only if I don't want to save money by not upgrading.  USB wacom tablets
aren't that cheap, nor are USB lasers.  One of these days I'll by a
USB->Serial port adapter and see if they live up as claimed when working
with my devices.

Isn't it possible to use a SCSI->ESDI board?  Or does that only work for
hooking ESDI drives to SCSI controllers?

There are hot-swapable IDE Raids out there.   They are expensive though.
I don't see them around much, but when I do, they are usually being
pitched to SGI owners (cheap video storage).  I'd love to pick one of
those up.  Then, I get less downtime while still being able to get the
cheap drives.

That thing you get with a zx board for your SS20, or some other board for
the Dec 3000.  The accelerator for the Dec 3000 actually wasn't supposed
to be half bad.  But, it is only supported by Dunix, and it didn't support

That's fine, since most of the Matrix work in PC land happens in the CPU,
unless you are using OpenGL capable software and a Geforce or Radeon card.
And I don't think that hardware transformations are supported under linux
with those cards.

Time to get the landlord to pump the extra water out of you house then.
It's not good to have water near computers, but water near the monitors is
especially bad. :)
