Richard, I went a step further by actually interfacing that board to
my 8080 home brew system. At that time having 128 bytes of RAM was a
big deal. That 2K of core memory was cheaper than adding 2K of RAM.
Those were the days when you could create music by using toggle
switches to enter your binary code to create a set of program loops
and by putting a AM transistor radio close to your computer to hear
the sound you generated.
