Dwight,
I would be very interested in your NC4016 experience. I did collect a
NC4016 STD bus board a while ago from ePay, and have successfully spoken to
it via a terminal - It would be fun to add storage, but I have no idea
where to start :-)
And no doco......:-/
Kindest regards,
Doug Jackson

Be nice to your parents.
Go outside and do something awesome - Draw, paint, walk, setup a
radio station, go fishing or sailing - just do something that makes you
happy.

I have one of the NC4016 boards ( I forget which one
). I added a XT
floppy controller and a XT MFM disk controller. I made some other hardware
for doing byte stuff faster. Using address -1, I could access it faster as
a short literal. I had a 8 bit barrel shifter there. It came in handy for
the XT controllers. The processor was fast enough that I had to add delays
to the code to the floppy controller. It would run faster than the floppy
controller could provide status. Still, I was using it with direct
processor access and the controller was really expected to be used with a
DMA transfers in a XT computer. The MFM hard drive controller was much
easier to deal with.
National also had a bunch of stackable computer modules. One of these
modules had the NSC800 processor with a Forth ROM built in.
Rockwell liked Forth and used it quite a bit in their development system
as well as having it on their AIM 65 machines.

Rockwell also had an RSC-FORTH Kernel and development environment ROM set
for the R6501Q, which is a similar 6502-based processor meant for embedded
applications.
