Has anyone built the ciruits listed on Brians page for controlling power to the Monitor? I went to Radio Shack and could not find the transistor (TR1 - BC237).
Fro the 7404 Hex inverter I used a 7400 series TTL IC model (Type 7404 cat number RSU 11627296)
and for the 4510 BCD I used a 4000 series standard CMOS (Type4510B) Catalag number rsu 11516937)
Can anyone help with this? Am I the only one that has attempted to build this?
Thanks
john
