If that has one of the original hard disks, then a
disproportionate
amount of the power is goingto thehard disk. Replacing it with a more
"modern" hard disk might free up enough power to dothe job.
It has a 20MB 3.5" ST506/ST412 drive with bolt-on adapter card that
lets it appear to be a native embedded IDE drive. The ISA controller
is an ordinary Compaq-badged WD IDE/floppy card.
I found that using an ST-4096 was pushing the limits
for Compaq portable
power supplies.
No doubt! That one will put a noticable load on a DEC BA-23 chassis.
Be aware that the internal CRT is EGA compatible!
Interesting. I had no idea.
(Compaq video boards are recognizable by the extra
dual row header in
the middle of the board for connecting the internal monitor).
That I did know.
