If it works I'd like to see a pic, doesnt matter if its still messy, a look at the insides would be great.

Would anyone here be interested in the circuit diagram of my simple Videopac/Odyssey2 cartridge reader device?

Here it is:

It may look more complicated than it really is. Like I said it basically consists of 4 IC's, a switch and 3 connectors (for the cartridge, the power supply and the serial data output).

Finally a picture of the finished Videopac/Odyssey2 cartridge reader:
(top and backside)

It can also be used to copy a cartridge to my EEprom cart.

No, only 4:
- CD 4060
- 74LS390
- CD 4040
- CD 4067

The 74LS390 contains 2 equal counters, these are drawn separately in the schematic.

What program is used for programming?

Huh? No programming is required. To read the data from the cart I use the ODYREAD.EXE program. (I wish I had a better program.)
