Completed the Flash ROM update utility which loads the system firmware into the Flash ROM for the MC68SZ328 to execute on power up.
It takes a ROM image file from the SDcard, blank checks the Flash rom & erases it as needed, then programs the image into the device.
Next job was to finalise all the changes to the FPGA pinout & logic, and update the firmware accordingly.
So far so good. Both new models boot Microbee disk images:
64 key model 98 key model
