Created a branch which simulates controlling a CPU memory from the Front Panel. Made the memory an 8KB, Dual Port SRAM in the CPU. Able to read/write the memory.

It works!

Front Panel controls are:

The bottom 8 Pushbuttons/LEDS control d0-d7 of the SRAM.

The middle 16 Pushbuttons/LEDs control A0-A15 of the SRAM.

The top 8 pushbuttons control:

• RUN/HALT (toggle pushbutton)
  • CPU is running when lit (Run is not used in this case simce there's no CPU being controlled)
• INCADR (debounced pushbutton)
  • Stores data then increments address when in SETDAT mode
  • Increments address when not in SETDAT mode
• SETDAT (toggle pushbutton)
  • When pressed/lit allows Data pushbuttons to change memory data
• SETADR (toggle pushbutton)
  • When pressed/lit allows Address pushbuttons to change memory address
