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
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
