[Coco] Expanding 4K Coco Mem

[Camillus Blockx]

Hi, Jim

If you overlook the color basic unravelled listing, then there is not only the cassette buffer, but also the 2 x 256 byte sector space that is normally reserved for diskbasic. I do not know if Color Basic takes this space if it does not see a diskbasic rom. You have to look in the assembly code to see.

Good luck

If Darren's suggestion is correct that it is the 256K line buffer and a
buffer for possible cassette data file output that explains why there is
only 2343 bytes left for a program, is there any magical set of pokes that
would allow those buffers to be "turned off" so that the mem could be used
by a program? I think my Tetris just needs about 500 more bytes to fit.
