Risc PC CPU Oscillator/Crystal

Post by Ottly » Thu May 24, 2018 7:56 pm

Hi All,

I have a spare dead Risc PC 710 CPU I got when I purchased my RISC pc. I thought I’d plug it in and probe the crystal to see if it was outputting a clock signal. It’s not. So I’m trying to source 80MHZ 4 pin DIP crystal. RS online and element 14 don’t seem to have this type. Anyone able to point me in the right direction?

Thanks Scott.

I've bought oscillators with that footprint from Surplectronics in the past.

They seem to have an 80MHz oscillator in stock but you'll need to check the footprint and voltage etc.
