Hi all, quick question, Pronto-PET had a neat little reset switch which on a quick press performed a reset but if you held in the switch it would pull the diagnostic line down and reset the pet into monitor mode. All mounted in a compact box.
Anyone got a circuit diagram for such a reset switch or the best design for a compact circuit
it’s in a very small box maybe 1.5cm by 3 cm … only connections to the motherboard are pin 22 j4, pin 25 j4 and pin 20 j9
