ODT 1.0 on clone 486/25

[Michael Squires]

Well, it looks like you can add a genuine 486-25 clone to the list of
systems that work while running SCO ODT 1.0.  The system is a BSI 486-25
luggable using the Orchid PC III Plus VGA plasma lunchbox.  I had to
swap the Future Domain SCSI controller for a Adaptec 1542B, but everything
else is fine.  HD is a Micropolis 345MB half-height SCSI drive.

There appears to be two different Orchid VGA plasma designs.  One uses
a proprietary VGA card that runs a little slower than other cards but
which has much higher contrast (VGA Plus).  The other uses a standard
VGA card with a piggyback card that translates signals for the VGA plasma
display; this apparently can be used with 1024x768 cards (in 640x480 16
color mode only) but an external monitor can be used to get higher resolutions.

The system benchmarks at 13,000 Dhrystones/sec under MS-DOS (it dual-boots).
It's rather funky seeing xload and xclock on a portable....
