Yes I built one for my final project at DeVry....I used a Vic20 and an 8 bi t to 16 bit decoder and had to build gear boxes and motors to replace the s ingle planetary gear...I still have whats left of it and I know I have the magazine somewhere lol...It worked but kept popping transistors I tried to switch to relays but the Vic had a pulsed output that wouldn't trip the re lays.
