Evening folks, (it's evening here)
Typically for troubleshooting around $FESTIVAL I find a more-than-likely dead MC14081B (CMOS quad dual-input AND gates) just as UK postage ends for the next few days so getting a replacement won't happen until next week. Question is, aside from having to make up an adapter board to change the pins around and making sure Vcc is +5V is there any reason I can't use something like a 74LS08 for testing? One of the outputs is RESET for an 8085A so nothing too demanding. (I might have a CD4081B somewhere too, which is pin compatible according to the datasheet) Cheers, -- Adrian/Witchy Binary Dinosaurs creator/curator Www.binarydinosaurs.co.uk - the UK's biggest private home computer collection?
