  • BrunWord 464 works on any CPC 464, 664, or 6128. According to the manual, this comes on disc, too, ie. not on cassette (?)

ROM Cartridge and 8bit Status Port

Technical

ROM version has a size of 256K. It is split into 16K pages. 2 Pages are standard CPC roms, one of which is a "extension rom". Part of the Brunword word processor is copied into RAM, the "extension rom" does most of this.

The ROM Select port (&DF00) is decoded and has 2 roles. First is to select which ROM page appears in the range &C000-&FFFF of the Z80's address space. The second role (when bit 5,4 are used), makes a page visible in the range &4000-&FFFF of the Z80's address space.

The exact decoding of the ROM select port is unknown. The exact function of all the data bits is not known.
