EBay prices yield systems for $5 to $10 (plus shipping), but the EDTASM cart is over $30. I have not found a non-eBay source that actually had a cart for sale at all. I don't quite have the knowledge to do it, but something I'd really like to see is a reverse-engineered equivalent (editor, assembler, monitor) implemented and available as an inexpensive cassette tape or downloadable sound file that could be played into the cassette port (or even, shudder, READ-DATA/POKE basic program to type in) and an accompanying public-domain manual. I know this would be vulnerable to getting overwritten by an out-of-control assembly program, and the ROM version is preferable, but it sure would turn a cheap, otherwise very capable BASIC platform into a cheap, very capable Assembly language platform that one occasionally had to re-load.
