Renovation of a tried and tested commercial design. Not my own design!
I have the manual, circuit diagram and working boards.
The PAL chips have been read, analysed and recreated.
I modified the board to accept larger RAM chips, and ported EH-BASIC onto it.
As the 68008 is the best fit for interfacing the STEbus, I have used it as the exemplar for future designs.
STEbus 68008 files. Manual, circuit, logic, pictures.
