The best & easiest ROM to make!


How it works:


(1) Select which line (BJT) to 'Enable'.
(2) Each line drives three diodes.
(3) SPST switch indicates diode as High/Low.
(4) LEDs return address for line from 000 to 111.

##### For Example #####

- Turn on top BJT
- Enable or Disable diodes with switch.
- LEDs return address.

Very simple proof of concept. Enjoy!
