You're showing your age Ski... I hadn't been born yet when the TRS-80 hit the streets... but it's good to know that it works with a PIC for when I get to be curator in some museum somewhere... and need to demonstrate that our ancestors once walked upon the earth with brains no bigger than 8kb... (OK it probably had more than that, but there was always that abomination of design called a Commodore PET).
