Does anyone know how to read the system clock on a NEC 8500 laptop
from CP/M ?

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.

RS carries the manuals as a special order item.  There is also a disk
drive diagnostic program (used in testing the Model 16/16a/6000) that
is used for disk drive alignment.  The former is not expensive; the
latter is.  The system also uses standard 8" drives; you could
disconnect them from the II electronics and run a cable to a system
for which DDD does work.

I believe that the II does use the WD 17XX chip. The controller is not
very good (disks that do not work on it work fine on my IMSAI with
Tarbell DD controller).
