More than 10 years ago I found Anthony Good’s homepage. Then there was instructions to build pic-microprocessor based memory keyer which has every option i needed, or even could imagine. I built couple of them for my friends and for me, and it was in use until I found that he has new version made with arduino. Of course I built it too and it is excellent.

Here is few low quality (only vga quality cam in phones back then) pictures about original PIC-version.
