Atari 7800 Combo Video & BIOS Mod

Alternate install for both the video and BIOS mod, working perfectly.  Notice the chip on the far right?  It’s the 74LS04, touching the board with only 5V and GND. 🙂

Also, one of the signals going to the 174 has been intercepted near the potentiometers in the middle of the board.

    • Much has happened very slowly…
    • We have been thinking about an even better way to get data back from the MCP cart.
    • MCP devkit now supports read-back from the cart or stock RAM!
