Trade Motorola MC6821PIA

[James]

Hi all,

Looking for a Motorola MC6821 or MC6820 PIA for Williams Driver Board, as getting a sole +5V reading on a single pin (pin 8) causing a locking coil .

Can't seem to locate any online or through usual channels.

Is it 6821 or 6281 ?

 

[James]

Sorry, 6821, or 6820, attention to detail

@75p each here, I am guessing, the wait from China is an issue, but are they likely to work?

Might as well get some in, then others if need can have them.

I got a load of these in the end, think I have quite a few(5 or 6) left, if anyone needs let me know, happy to trade for other parts (Own SS and NF), or postage and whatever really.
