I've got both, selling both to fund some more Apple purchases
Mega 1 only includes the computer and power cord. It powers on and has the "loading sound" once light turns green.
Mega 2 also just the computer, been in my PC for years. Tested and working a while ago. Both sold as-is.
I no longer have an Atari monitor, but might be able to hook these up to see where they're at. Pics if requested, also as far as asking prices I don't really know.
Just thinking about $20 for shipping, each. I'm in Houston, TX. Thanks.
Edit: Mega 2 is spoken for.
