I agree that it's easier to talk to tech support at GVP than at CBM
(any epsilon (no matter *how* small)) > 0!! As for the GVP setup...
Give me a life!!! Their installation software sucks moose mucus.
At the time I didn't have 1.3 roms and yet I wanted to do something
as outrageous as partitioning my Q80 in something other than 2 40M
partitions.  Does anyone else wonder what the 1.3 roms & partitioning
have do to w/ each other???  Their first disk would not allow for
used defined partitions (& was actually 1.2 based) & their *new*
revised software assumed 1.3 roms.  In short I had to hack up both
versions to do what I wanted to do. 

I generally *liked* the GVP (it was quite fast) but most of the performance
was do to the Q80.  As for design, what about MAX TRANSFER, the brain
damaged cousin of Mr. Headroom.  If your requests are over 8192
*watch out*. IF YOU DON'T SET THIS PARAMETER W/ gvp YOU'LL GET
FILES OF THE CORRECT SIZE BUT THEY'LL BE CORRUPTED. 'Nough said?

 I now have a 2500 & w/out setcpu yet w/ the ST506 Rodime (& the 2090A)
 was as quick as the GVP w/ the Q80. The Q80 + 2090A w/ setcpu
 is *very* fast. (Thanks Dave...).
