It's so new.. that there's little/no formal documentation.. I have been successful in programming mine with cartridge images it came with the drivewire rom as one of the defaults so it is easy to set up a drivewire server to transfer data
CocoFLASH is a multi-ROM cartridge system for the TANDY Color COmputer Models 1,2 and 3.
The unit offers the following features:
- 8 Megabyte of FLASH ROM storage, enough for 1000 8kB ROM images, or 512 16K images
- 64kB of EEPROM storage (for game save storage, or other data)
- Orchestra 90 compatibility (including stereo out capability)
- 2 user defined switches
- 1 user defined LED
- cartridge bank support (ala RoboCop, up to 1MB cart size)
- requires only 4 bytes of IO space
- IO base register can be modified by software to anywhere in $ff40-$ff7f)
- IO registers can be "hidden"
- Optional Robocop "offset" register
- dual offset capability (master 4kB bank register + optional 16kB offset register)
- programmatic "autostart" capability
- Manufacturer and Device ID registers
I have tested the orchestra portion and it works well. I've also successfully loaded two 16k cart roms and two 32k roms in mine.. Some conversion was required to make them loadable they have to be broken up into 16k blocks and load at a specific memory address: cartridge images must be converted to CoCo format .bin files that load at &H4000 to use with the writing software.
The menu system is a basic program and is easily modified and reflashed onto the device.
