Tag: 8 bit ide

Adds CompactFlash storage to an RC2014 through a simple 8-bit IDE interface.

The project supplies a schematic, Gerbers, and build documentation, and lists kit and bare-PCB suppliers; an assembled version is not offered. The unbuffered IDE connection must remain short, not every CompactFlash card is compatible, and the maker says older cards tend to work better. Power the CompactFlash adapter directly from SC145 as documented.

Adds CompactFlash storage to RC2014 and RCBus systems at I/O ports 0x10 through 0x17.

Both designs have schematics, Gerbers, PCB files, and kit or bare-PCB paths; assembled versions are not offered. Plain CP/M 2.2 can address the first 128MB and RomWBW up to 2GB. The maker recommends avoiding high-capacity, high-speed cards and documents a critical 5 V power issue with some visually identical CompactFlash adapters.
