Same thing with my Apple II. Another classic, my Compaq portable wasn't behaving too well, last time I tried it. It took a few whacks on the side, before it would start up. My newer, but retired, Macs all seem to have floppy drive problems these days. I had to to disassemble and really clean out and lube the imagewriter before it would work properly. I'm still waiting for replacement sound insulation foam to arrive before I refoam it and put the cover back on. My conclusion, is that the best way to keep stuff running, is to use it. Hi Mike,

When I put them in storage they all worked perfectly. Mike,

The schematic for the Apple II version is on this page (the LM319 was omitted in the microcontroller version). http://www.willegal.net/photo/repair/besttester.htm You could use the artwork to generate a schematic or look at my Apple II version which has a slightly more complicated implementation.

I think I'm going to use a photodiode and a voltage comparator, and a PIC 32 or something. I'd be interested to see how you made yours, could you provide a schematic for? It'd be greatly appreciated if you still have it somewhere. Thank you! Kind regards, Josh Hello Mike,
