The '''FO-DOS Cartridge''' is a BIOS/BASIC 1.1 ROM upgrade for the CPC 464 from [[Duchet Computers]]. The cartridge contains a 32K BIOS/BASIC EPROM, two diodes, a LED, and a switch (for switching between old/new ROM).
Combining the FO-DOS cartridge with an additional [[Standard Memory Expansions|Standard Memory Expansion]] expansion and an external [[Amstrad Disk Drive|DDI-1]] disc drive would almost upgrade Contains a CPC464 to 32K BIOS/BASIC EPROM, two diodes, a LED, and a CPC6128. But the CPC464 would still not be able to use RAM configuratins &7FC1 or &7FC3 f. eswitch (for switching between old/new ROM).
Exact EPROM content is unknown. It might be Combining the FO-DOS with an original or modified, english or french additional [[Standard Memory Expansions|Standard Memory Expansion]] expansion and an external [[Amstrad Disk Drive|DDI-1]] disc drive would almost upgrade a CPC464 to a CPC6128 BIOS ROM...? (being made in 1989 it probably has the newer french rom). From cpcrulez forum: Boot messages says "...v3 (1985)... basic 1.1"

:Hey while we're in Duchet products, the new version of the Hacker arrived. Just change a little ROM and voila: Version 7.0 brings an extra assembler. Then you fiddle with machine language!
