Hi all,

I managed to get the old (new) EDUC-8 beast working.

I had a lot of help from a kind person who has a real working EDUC-8 who helped to make sure all the logic was correct.

Attached is a photo of my EDUC-8 board which is much more compact than the original. Both the Windows emulator and the board show the result of multiplying 11 by 11 and shown in the accumulator register (bottom left row of LEDs)

I still have to do code for the hardware input/output but I have to wait for a new PCB design coming which supports the 3 serial IO ports and the parallel input port. It also allows using sub miniature toggle switches as well as the cheaper but larger ones shown.

The Windows EDUC-8 emulator also supports connectable modules for all the peripherals that were described in the original articles. These include LED displays, Keypad, ASCII keyboard, Melody Player, Paper Tape Punch/Reader, Magnetic Tape Storage, and a Mosaic Printer

I could not recreate the old Burroughs self scan display module as I cannot find information on it.

If anyone wants to play with the emulator, it is available at
