Hi Dwight,
The WD1002 card number does sound familiar. I'm almost sure that is it.
Thanks for the information. I appreciate it.

I suspect Kip had a WD1002. It would have had a BIOS PROM on it. I used
one of
these on my NC4016 computer. I'd also purchased
several 5Meg drives for about $5 ea as DOS no longer
supported it. These
worked fine for my NC4016. I used this to add new
instructions to CM-Forth since the processor had a
number of useful side
effects. I could recompile CM-Forth in less than 15 seconds.
Not that big a deal now days but in the time when the
hot Intel processor
was a 386, it was quite impressive.
Dwight

I have a hard disk controller for my Heath H100 that uses the 8x300.
I didn't realize how common that design was...
