Hi Brek,
Nice job, I immediately recognized the "... Next Tuesday" phrase and had a chuckle! You are dead right - not too many people are aware of the term. I recall a long time ago sending an email to a manager (copied to his staff) who was a caring, understanding, nineties type of guy which had the desired effect of him pulling his head in a bit and thereafter was quite approachable.
I still have one of those SPO256 chips (and its mate, a text to speech IIRC) around somewhere that I wired like yours with a heap of wirewrap and pins. If I'm not mistaken GI became Microchip or was absorbed by them a long time ago.
Kind regards,
Bill
