Isn't PGA Pin-Grid-Array? (It's probably wrong, but hay....)

How large is all this equipment, in square and cubic feet? What sort
of power does it take? Anything particularly interesting or novel
about this system? MicroVAX III circa 1987, KA650 processor, QBUS,
~32 meg RAM, RA-82s are ~600 meg, VMS 5.x? Roughly 2.8 VUP?
Main unit, rack-mount half-height? Maybe a TU-81+, half-height rack tape?

VS2k, uV2k and MV-II and a bunch of others. However if you have the
manual....RTFM comes to mind. :)
The NI boot protocal for small vaxen is MOP, to explain that requires a
book...come to think of it you may have that in your book.

I never heard of 320 x 200 x 16 for the CGA - I seem to remember 160 x
200 x 16 - surely it would not have had the memory for the other?
The CGA never did 640 x 400 x 2 that I ever heard of - I assume that was
a typing error for 640 x 200 x 2.
The EGA did 640 x 200 x 16 on a CGA monitor, 640 x [was it 400 or was it
350] x [a number of colours dependent on the memory installed] on an EGA
monitor, and even did 640 x 350 x 3 (I think) on an MDA monitor.
I also once saw a demonstration on a CGA card that changed colours in
real time faster than the scan rate and so gave more colours than you'd
expect.
But I digress. What was the question again? :-)

i have one also, but the front plastic panel is missing. concerning the disk

And PCI can also Mac.

You have three bootable devices...
B DUA0 *RD5x in the box, never seen one external but it can be done.
B MUA0 or 7 *tk50 tape I forget the device number as it's slow.
B XQA0 *boot via eithernet. It was possible to run them diskless.
B does the default device first (dua0) then tape then eithernet.

I'm sure everyone knows about this, but for the few, such as I:
For a bunch of CPM systems, 68k, 8080, Z80, Z180, CPM-86, MPM, checkout:
http://cdl.uta.edu/cpm/download.html
They have it all including CPM-86 OS + C compilers, Basic Compilers,
Fortran and Pascal.
Plus the same for CPM Z80 & 8080 system:
Plus, the Digital Research Library with
GEM stuff for Atari and DOS, including GEM Desktop, Draw, Write, and GEM
Publisher
You could have a good 8088 or 8080/Z80 or Atari system, for just a
little time.
