I recently received an Intel 386 box from a friend who no longer wants it
(what a nice friend :>).  The problem is that he does not have manuals
for it.  If this was the 302 AT bus motherboard, I wouldn't be asking
for help since I know how to fix it.  Unfortunately, this is the Multibus
I version of the 386 board and I know very little about this.

The scoop is: it works and run an early SysV.3.0 (very early, crashes
constantly, just look at it wrong and kapow!).  Any help as to where and
how I could get manuals and update software for this beast is appreciated.

I've called Interactive Systems in the hope of getting a new UNIX for
this (the UNIX on the machine has ISC copyrights), but they said they
don't sell UNIX for Multibus machines...  Does Intel sells new versions
for this board?

The hardware seems to be stable, just the OS crashing that gets to me.
It's hard to develop software on a machine that crashes every few minutes.
I'd even be willing to port Minix to it, if I can get some docs on its
hardware internals (registers, port addresses, etc.).

If all else fails, I'll start calling the local Intel office (the problem
is that they are a 'fair' size corp, and I could get the 'musical phone'
routine where they forward me to various depts).
