hi I am playing with an old Motorola board and I have a problem As you well know, 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 differenly 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 allCPU: 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? Do you happen to have for sale? here I am Thanks!
