First, It is a MC68000 CPU socket converter from DIL64 to PLCC68.

Do not populate the accelerator area (north) if you only want to use it as a converter!

You only have build the 64 pins, the PLCC part and just connect the middle jumpers to use the original 7mhz signals!

This part is TESTED and working.

A bit tricky to build but also handy

Second......if you have a 68HC000, this type can run 7-50mhz.

The "accelerator area" is experimental, easy to build but !!!NOT TESTED!!!

I want to do experiments in future but if you do it first .....I am interested in the result :)

If you want to do a test program, you have to populate this area.. CUT ALL Middle JUMPERS or it will be mixed and lead back to the original signals!!!

It uses a Xilinx 9536 44VQ and can be programmed on board with Impact.

Use zip and Eagle file to see connections.

XILINX INPUT SIGNALS:

DTACK to pin23

CLK (7M) to pin28

CLK 2 to pin38

AS to pin29

E to pin31

VPA to pin33

AMV to pin36

XILINX OUTPUT SIGNALS:

pin27 to DTACK

pin30 to AS

pin32 to E

pin34 to VPA

pin37 to AMV
