Got the Front panel working with a MC6800 FPGA CPU. FPGA Build is here. Same button/LED arrangement.
- RUN/Halt Pushbutton - Stop CPU and enable Front Panel control of memory.
- SETADR button/LED - Allows an address to be entered.
- SETDAT button/LED - Allows data to be entered to load into SRAM.
- INCADR - If SETDAT is active, writes to SRAM then increments address. If SETDAT is not active examines the next memory location.
