Well my PK-88 Terminal Node Controller still powers on and flashes its LEDs during boot after being in storage since the early 90s!
Now I’ve just got to…

B) find a DB9-DB25 RS232 adapter in my old bag of serial cable kit
C) persuade lots of amateurs that they too want to recreate the 1200 baud Packet Radio network we had in the 90s before The Internet #RetroCommunications
