Got an 8256 here (those things should be as common as fleas in the
UK, I'd think. Getting a 120V 60Hz one here was a little less easy).
The service manuals I have to hand make no reference to a 120V model. The
PSU is a switcher, producing 350V DC (or so) from our 240V mains, and it
would be easy to modify that to a voltage doubler for 120V mains input,
but the smoothing capacitor is just a single componentm not 2 in series,
so the changes would be more than in some other supplies.
I've installed two 720K (Teac FD235F) 3.5" drives, both to get
something that will work with available media and also to get more
storage. The Joyce uses single-sided 3" disks. With a simple one-
Actually, the standard configuration has drive 0 as a single-head 40
cylinder drive taking 'flippy' disks and the optional drive 1 as a
double-head 80 cylidner drive. The latter was much the same logically as
