A friend of mine has just ported Manic Miner to the Parallax Propeller chip!
Apparently the game is playable, and only requires the Propeller chip and a few passive components to work.
Here is what He said about it,
whats the minimum hardware needed?
prop + crystal + 3 resisters for video + 2 resisters + 2 caps for sound + 1 resister & 24LC512 or greater + 3.3V power
+ prop plug ( programmer ),
prop plug Â£20 ( expensive part ) as it’s USB to rs232
prop chip is Â£9
oh, forgot you need a TV too lol
+ PS/2 keyboard
So, for a few pounds you can build your own stand-alons Manic Miner hardware. Not quite a 30game DTV, but getting there.
