Current Status: Fully Functional

We received eight of these microprocessor trainers on 5/24/2022.

Unfortunately, they did not include any copies of the companion book ("Practical Microprocessors") or the Service Manual. They are still potentially useful as technology demonstrators (i.e. "hey, you soldered a badge- this is what can happen if you scale up from there")

We did find the assembler code for the ROM, which is helpful for running the ROM demo programs.
  - 04D7 - Echo - display input switches to output LEDs
  - 04E0 - AND Gate Program (lights LED if all input switches are ON)
  - 04F8 - Conveyor Belt Controller
  - 053E - Well-Tempered Microprocessor (plays random tones) (tested successfully)
  - 055A - Squirrel Feedback Shift Register Display
  - 0599 - Organ (plays tones from keys)
  - 05F9 - Rocket Blast Off (tested successfully)
  - 0662 - Stopwatch
  - 06C2 - Snake Paddle game (how does this work? keys or do you need some kind of paddle?)
  - 07F0 - Lesson 3 Counter Program
  - 0800 - Default Program Counter Location (I guess your own programs would start here?)

To run these programs, press RESET, FETCH ADRS, (enter the 4 character address), and RUN.
