Rockwell made many 6502 variants. Some were ‘SOCs’, complete computers in an IC.
and Rockwell was strong in Forth, e.g. RSC-Forth products
The Databooks (e.g. 1984 and 1987 Data products) contain many examples of these lines.
In my collection I have two:
- R6501Q one IC R6501AQ and one R6501Q in the Glitchworks R6501Q kit
- R65F11 one IC, a ‘Forth’ computer
