I'm slowly starting to figure out what I want to do- the suggestions from the group
seem to point towards 6809 or IMS6100 for the processor, so now I'm looking at
representative designs to springboard from (first project). Found several online 6809
designs, but only one 6100 (at www.sparetimegizmos.com) Are there any good print resources
on these? (other than the bitsavers/manx resources on PDP-8 and DECmates)? (I have
datasheets)

I have the Intercept Jr. technical docs. That gives you the docs
for a machine that uses the 6100 processor.

Thanks :-) If you have any questions about it, let me know...
Just to set the record straight, the SBC6120 is a 6120 based design, NOT
the 6100. Don't know if that matters to you or not.
I actually built (got as far as one assembled prototype) a 6100 design
that was an updated Intercept Jr. It had a full 4K memory, a real KL8E
compatible serial port, and could run any of the PDP-8 paper tape software.
It also had the obligatory 7 segment led address/data display and twelve
button keyboard.
Never finished the firmware for it, I'm afraid. I might some day, but the
interest is pretty light.
And sadly, any practical 6100 design will never run OS/8 without a lot of
extra hardware to implement the EMA.
