Are you sure the drive is ESDI? I think the model 70 shipped with an IDE

I have no idea about worth, I guess they are only worth what we PS/2 fans
are willing to pay for them. Personally I probably wouldn't pay more than
maybe $25-30 or so for one, with or without a monitor.

As far as an operating system goes, I know Linux supports the MCA arch,
but most Linux distributions do not ship a boot kernel with MCA support
compiled in. Since you have a small drive, you'd also want a distribution
with a small footprint. Anyone have any recommendations on a particular

If I remember correctly, the 8514/A adapter needed an 8514 monitor to do
anything more than 640x480x16 since it used odd frequencies. Maybe a
