SDC68k_2: The new version with MC68SEC000.
SDC68k_1: The PCB has the size of DIL64 socket. The only non-trivial component is an STM32 micro, serving as memory, peripherals and glue logic for M68k CPU. It also provides full hardware monitoring - memory editing, .HEX file loading and single-stepping/breakpointing on bus cycle or instruction basis.
SDC68k_2 now achieving speeds equivalent to 2.5 MHz 0WS. Monitor firmware was modified to use color text
After some firmware tuning, the MC68k running at 5 MHz achieves the speed equivalent to 1.58 MHz 0WS.
Firmware operation verified. Need to add some basic MMU functionality for demoing access error handling. The performance is not astonishing - about 300 k bus transfer per second.
The project is very interesting. Tell me more! Schematic? Block diagram? SW?
Thanks!
So a 68000 on one side and an STM32 on the other to take care of housekeeping? Wow!

this is one really sick sh*t! Congratulations!
