[Coco] CoCo 512K EEPROM+External Controller Walkthrough (Final)

[Chad H]

If you mean like the CoCoSDC...no.  What it is doing is mapping in 8K/16K/32K pages of the EEPROM memory into the CoCo Cartridge memory space and switching address lines A13-A18 to control this as needed.  You can put HDBDOS, etc. here and it would be good for a DriveWire setup.  If you could have programs make use of the EEPROM banks, sure it's up to whatever you can come up with.  But it wasn’t made to write to it like a virtual disk controller.  That was what the CoCoSDC was made for (SD card for storage).

Chad, can this be used instead of a disk controller? I mean burn DECB in a bank and boot from that then use the rest (maybe in banks) for storage  and to run programs loaded into the EEPROM. With 512K there isn't much room, but enough to boot, run something like  word processor, and still have enough room for a good many files, at least a 180K disk full. Along with DriveWire that would be a great setup -- keep 2-3 programs/games you use most in the EEPROM with a little extra storage, use DriveWire for any additional. If set up as a word processor you may never need anything except to print. 

Now we need something like an Arduino programmed with a basic print driver that will just plug between the CoCo and a simple USB printer. If it just had a single character set it would fit most users needs -- be able to print a program listing or something simple. Wouldn't be good for word processing or graphics, but a cheap and simple line printer would be great!
