Hi Timbucus,
I was one of the people who had a short chat with you on Saturday.
I dug my MK14 out today and tried to get it working, found a 74LS04 doing odd stuff (1V logic log, 4V logic high with 5V and 0V reading correctly on the chip legs, so binned off the "age appropriate" chip in it and stuck a new..ish one in.
Still not playing, so Ill investigate further another day.
Anyhow, nice to meet you and I loved your stand.
