apple II 120vAC control v1.0
This 8-outlet control box allows you to turn 120v AC devices On and Off using the four annunciator outputs of the apple II game port (with a little help from our Game Port Interface Board). We demonstrated this control box on Friday, July 21 at 9:45am at KansasFest - see the video at You can see how the box works through the clear plexiglass. Yes, we used 5v DC relays to isolate the 120v AC from the apple. So, no 'oops' on the power side will have an adverse effect on your vintage apple hardware.

FULL DISCLOSURE: we tested the 120vAC box on a IIgs, Platinum //e and //e - all tests worked fine. At kFest we acquired a ][+ and subsequent tests on that ][+ were disappointing. Turns out the annunciator outputs on our ][+ will change state if influenced by signal cross-talk (that can happen on a ribbon cable, or, parallel traces on a printed circuit board). So, we DO NOT recommend using the 120vAC box with a ][ or ][+ with GPIB (Game Port Interface Boards) revision 1.7 or older.
