The X-10 was a module that connected into the TI along with a cable that attached between the TI Joystick port and the X-10 household controller that controlled individual X-10 devices. The module software allows you to program the controller--and it then carries out the instructions. The computer is only necessary to make program changes. I have one. . .

The MBP (or MBP-II) PEB cards were probably the A/D cards you were thinking of. I think the last run of those was done by Cecure Electronics in the mid-1990s.

It is also possible to build a A/D board using the TI or Willforth prototype boards (or likely with the one I designed but I haven't done a run of these yet).

If you have designed a card for this please walk me thorough how you activate the A/D or clock to output data to certain memory addresses?
I want to understand how you decode the address lines to enable the output for certain memory addresses.
