This board is intended to stack on top of a Mojo FPGA development board (v2 or v3) and connect to it a 68SEC000 CPU.
This is the first part part of a multi-part project to slowly build a DIY computer based on the 68SEC000 CPU, using an FPGA to implement an MMU and graphics adapter.

Breakout board for QFP ICs.
This design allows QFP packages of up to 48 pins to be broken out to 0.1" header. The specially-designed chip footprint supports smaller pin counts via elongated pads that extend through the underside of the chip.
The board is two-sided; one side accepts 0.8mm pitch and the other side accepts 0.5mm pitch.
