65C02 CPU

Post by Vyper68 »

Has anyone fitted a 65C02 in and Oric. I know you can fit it in a BBC Micro and it uses less power and gives some extra instructions - but has anyone done it in an Oric?

Yes i did, here. It works with Cumana controler, but not on microdisc controler.

Here is the method : http://wiki.defence-force.org/doku.php? ... :cpu_65c02 (at the bottom of this page).

I also did adapter here (for 65C02/DIP and 65C02/Plcc).

So you cut pin 1 ?

I had a 65c02 in my Atmos for years. Worked fine with Cumana. I didn't cut any pins or joins others.
