Re: Improving Timex/Sinclair Tape Loading

So some very necessary reading / learning later... Yes an LED is polarised (light emitting DIODE). Clue was in the name I guess. It looks like the longer leg should be positive but it appears I can check this with the diode test setting of a multi-meter. Looking at various wiring diagrams for mono p...

Re: Improving Timex/Sinclair Tape Loading

I expected wire flying leads from the board to the switch as it was highly unlikely that the switch you had would have fitted the layout I had. This would also make putting the lil fella in a case easier as you would have free rein on the switch placement. You might consider putting the LED on wire...

Now. A bare board is available immediately. $4 plus shipping (which could be really cheap if you're in the U.S. -- I'll just throw it in an envelope 1st class mail).
