Try a 3B2/600  Starting price $36K Starting config: 4M RAM, 2x147M disks,
SCSI interface, 60M tape drive, 28 serial ports, Math Accelerator Unit,
VCACHE instruction cache, UNIX SVR3.1.1 [binary] with Windows and Graphics
[You will need a bit-mapped display with a layers module to use those two,
the cheapest available from AT&T is aprox $2,200]

It is has 12 expansion slots [going up] in each of which you can put
8port cards [or whatever] a little math will show that 4 come used.
The memory builds on another 12 slots [going down] only four of which
are defined for memory and one for VCACHE.  I dont know about the
othe seven. A total of 16M RAM possible.

the 3B2/500 is the same, but it has no "down" slots. [I don't know
where they put the memory.]  It has the same "up" slots and costs
someware in the low $20K range (so I hear).  The lower price would
hint a smaller disk space, but who knows?

Both are designed to act as network engines, they are very fast, but
the implementation of UNIX is a little weird.  Everything runs well
but the first time you "ps" after a long time, it takes about 15 sec.
other than that is uses threshold triggered virtual paging, and there
is a seprate "swapper" type program to process io service requests.
All good stuff.
