Uhhhh, yea, what he said. I forgot to mention the disk interface cartridge
in my last post... I have a few Disto mini-controllers (MC-1's) sans case
if you're interested... I think I have a PD dos available as well, as the
DOS chip (on ROM) is no longer available from RS.

Boy... y'all got everything over there, don't you? I've *never* seen a
T-proof Torx screwdriver on this side of the pond... therefore I just
tampered the tamperproofs to get in.
