BitVision (1974)

I don't know why they sold them in pairs, but it was supposed to be a learning tool for programming chips.
Sadly, the finnicky knob made it basically impossible to do anything useful in.

If the switch is in the DOWN position, it will just read out the contents of the memory address shown in the left digit, in the digit to the right.

When you flip the switch, it will enter into writing mode and let you modify the actual memory inside.
There is some code in the bottom sections and also a couple bytes in the top section.

If anybody can figure this out, please tell me!

P.S. Your changes dont save to anything, so you are free to reset it if you mess something up.

CPU: ???? (probably custom)Memory: 256 bytes + ??? IO
