[comp.os.cpm] Radio Schlock TRS80 Model II disc controller

tech@auvax.UUCP (Richard Loken) (08/16/88)

I need to play some intimate games with my model II disc controller but I know
nothing about it and taking the machine apart and peering at the board didn't
help.

Does the controller use a Western Digital chip like most of the world or is
this something the guys at Radio Shack devised?  I need such info to make the
Dysan DDD11.ASM disc analysis program work.

All this could have been avoided if the two people who said they had Model II
technical manuals had actually appeared with them.  Terry and Louis I won't
release your names in order to protect the guilty.
