The RRS3300 paper tape reader rewinds dangerously fast, slow it down using a sprocket hole tachometer. Can use virtually any 8-pin PIC uC but I will write the program for PIC16F18015. Applies only to instruments built with phase-control triac Soft Start board.

The Fluke 8060A handheld DMM's continuity test beep is about 2700 Hz and I can't hear it. This board plus firmware (PIC10F320-IOT or 322-IOT) shifts it to a lower frequency. Other parts are 2N7002, 470R 0805 and 1uF 1206. Cut off the ICSP header after programming.

HP 740B Chopper Photocell Driver board version 1.2, supersedes v1.0 . Increased creepage distance, EMI-hardened, and connectors up high to work in A16 position. (Fine for A17 too of course). Probably works in 741B and 419A.
