The Torch Graduate runs MS-DOS version 2.11. It only requires connection to the BBC Micro's 1MHz port, no ROM is required in the BBC Micro. When the Graduate is booted, 6502 code from the Torch 6502 ROM, is copied 256 bytes at a time into the BBC Micro's 1MHz Bus data page. This allows the BBC micro to boot before the Graduate completes booting MSDOS and installs the Graduate code in the BBC micro.
The Torch Graduate included the Psion Xchange software suite.
The Torch Graduate can be run in BBC mode using the Data Technologies Graduate DFS (GDFS) which is booted from the Graduate's disc instead of MSDOS.
