wtb: socket adaptor, M68020-PGA to M68EC020-PGA

Postby legacy » Thu Jun 07, 2018 12:59 am

The 68020 is a 32-bit microprocessor from Motorola, released in 1984. Motorola also manufactured MC68EC020 - embedded version of the MC68020 CPU, housed in different packages than the Motorola 68020 microprocessor, but even in the case of PGA package of 114-pin PGA, MC68020/PGA is not pin-to-pin compatible with M68EC020/PGA

They both use 114-pin PGA package, but some pins are different, (Vcc and gnd are placed differently in the pinout), and you need an adapter!

My board's socket is designed for M68EC020, but I need to use a M68020 chip because only the goldcap version, i.e. MC68020RC33 114-pin ceramic PGA, is available at 33Mhz.

Code: Select all

CPU: MC68020 114-pin PGA ----[adapter] ---> socket: MC68EC020 114-pin PGA

Do you happen to know *where* I can find an adaptor M68020-PGA to M68EC020 PGA?
