I had the thought I can build it this way to have a one-sided board:
====================================
||||||| || || || <=== 3x 40-pin
80386 =======================
|||| <=== Proprietary 120+pin adapter
=====[ FPGA ]==================
And I may be able to build it this way:
=======================
|||| |||||||
=====[ FPGA ]================== 80386
Where the 80386 plugs directly into the proprietary 120+pin adapter.
This would give me a framework where I can create the custom board
to use the appropriate GPIO pins, and +3.3 and GND pins, to provide
power to the CPU. My goal then is to generate the double-pumped
clock at 2 MHz, and respond to the bus signals with a state machine,
and provide a memory controller for the actual instructions.
Will anybody help me?
