Hi, all.  To answer some questions, I currently own a VS2000 and a 
MV2000, each using Clearpoint memory expansions, to give me a total of 
16Mb.  The SCSI-like connector has been of some debate over the years, 
but is not compatible with SCSI, from what I was able to gather.  I have 
the pin-outs somewhere, along with a few articles about the console 
subsystem, memory, displays, etc. for the 2000.  If I can dig them up, 
I'll announce it.

My VS2000 is decked out with the extra memory, RD54, and a TK50.  I have 
two smaller RD-type drives on MV2000.  If any other info is desired about 
these old machines, please don't desitate to e-mail.
