to add tos rom-space on booster board with jumpers, people can still use roms on many mainboards
Yes at this moment that board is for MEGA ST computer, but idea is DIL 64 pin socked board can be used anywhere.

KAOS 1.42 is fully 68020/68030 compatible. It was part of some German 68030 accelerators sold by Wacker Elektronik, Karlsruhe.

I tested the card in the MegaSTE.. and it didn't explode. So at least that's good.
But of course it doesn't work yet. I updated the status page with my findings. More test next weekend once I fix more of the CPLD code.
I think there might be some error in the Motorola AN944.
