Cactus Updates!
#1: RS232 works well enough that the H89 considers it a viable signal
#2: A shipment of parts arrived a day early, so I replaced all of the remaining non-74HCT series logic. It also meant I got some stuff to play with like EEPROMs and a 2K NVRAM chip.
#3: I converted a copy of the text based lunar lander game for BASIC for my purposes. This game is brutal, I keep slamming into the lunar surface at high speed, or running out of fuel when I think I’m doing well... DAMN IT!
