You need a disk interface cartridge. It fits into the
ROMpack slot, and
it contains a ROM containing the disk extenstions to BASIC and the disk
controller (WD1773 in later models, WD1793? in earlier ones). The disk
drive plugs into a 34 pin connector on the end of the cartridge
Late version disk interfaces (FD500 and later) work in all CoCo's. Early
interfaces need a 12V line (I forget if it's +ve or -ve) that's only
available on the CoCo1. Of course there's nothing to stop you hacking it.
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.

Tamperproof TORX screws. Drivers for them are available
from good tool
shops in the UK - I have a reasonably complete set to deal with such
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.
