This board lets you make a PLCC68 plug to fit in the STE's CPU socket.

It relocates the CPU and converts it to DIP64 to allow either the use of a traditional 68000 or one of the many expansions that assume a DIP64 configuration.

If using SIL socket strip for the DIP64 part, resistor networks may be fitted beneath the new CPU to strengthen the STE's bus pull-ups and improve stability.

Vertical clearance is extremely tight in the STE, fitting a socket or SIL socket strip will only allow the CPU to be fitted, to use other expansions, boards should be directly soldered to ensure vertical clearance (approximately 12-14mm is available).
