The drives are not much of a problem. TM100-1 with a power supply (-2, or
"360K" will work) Radio Shack did the drive select in the cable. So you
can either make your own cable and do "normal" drive select, or use the RS
cable and jumper all of the drive select positions on.
For running OS-9 (Microware, NOT APPLE!), I'd recommend change the cable
and use DS drives.

clip leads.
for more permanent usage, wire in an RCA jack.
Tony can probably remember the exact connection points, or contact

Some monitors are so flimsy that they can be damaged if you put a nail
through the CRT. For more temporary attachment, duct tape.
