  1. Im researching getting a MCP-Devcart from CPUWIZ. Can anyone explain the details of how this devcart works? If I understand correctly, its a cartridge that plugs into the 7800 and a cable that connects from the right joystick port to the pc. Am I correct so far? :) Does it connect to serial, parallel, or USB? Once I compile on the pc, how do I get the binary to the 7800? Are there command line utilities? Thanks in advance for the help!


  2. I'm new to the 7800. Just picked one up via Craig's List, and next thing I know a co-worker says he has one and gives it to me. So I'm the proud owner of two 7800's now.

     

    The first one I got is A3 87 5145173, board date is 2688. I just modded it for composite video a couple days ago.

    The second one I got (from co-worker) is A1 76 5908587 with expansion port, board date is 2387.

  3. I have an Atari 7800 that I've modded for composite video. Now I'd like to start learning how to write software for it. I'm already familiar with 6502 assembly (from the NES), but will need to do a deep dive into the MARIA chip (so far, how you access this seems crazy! :-o) and any other idiosyncrasies of the 7800. My question is, after writing and compiling on the PC (Windows), is there a way to run/test what I write on the real hardware? Or am I limited to running/testing in emulators on the PC? Something like a cartridge with a serial cable connected to the PC where I could compile on the PC and update the cartridge via the serial cable would be wonderful... does anything like that exist? I just had a vision of a Raspberry Pi Zero W in a 2600/7800 cartridge case connected to the PC over WiFi... LOL! :)
