Small sidenote:
A500s had lots of differnt disk-drives during the 7 years
of production ... those lousy big Matushit(a)s the big Chinon
(most common I would guess) 1" Epsons and mine even came with
an 1" TEAC (board revision 6) the 1"s should fit in the A1200,
but you may get a prob with eject-knob if it is a different brand.
It may also be that Escom-A1200 make some troubles, but C= ones
should be no prob.
