!65Host/ReadMe

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
This is 65Host, version 0.97/0.13.

Documentation on how to use 65Host can be found in Edition 2 of the
Archimedes User Guide.

The following remarks should be noted about this version of 65Host and its
documentation.

65Host provides a limited emulation of a BBC Model B Microcomputer only.
Access to the Archimedes printer port and serial port is not supported, and
there is no emulation of the Model B sound chip or disc controller. As a
consequence, copy-protected programs or those which attempt direct access to
DFS directory sectors are unlikely to operate correctly.

The User VIA chip is only accessible to the emulator when an I/O Expansion
Card is present. If a program uses the User VIA timers, it will not operate
correctly without an I/O Expansion Card being fitted.

Versions of programs which run on the BBC Master 128 or Master Compact may
use facilities not available on the BBC Model B, and so may not work under
this emulation.

The *-commands described in the User Guide (*ListROMs, *SwapROMs, *CacheROM,
*LinkROM, *EmulateBBC) are RISC OS *-commands provided by the emulator
module. *Quit, on the other hand, is provided within the emulated BBC
Microcomputer.

In addition the following *-commands are provided within the emulation:

*Reset [<number>]
Performs a 6502 reset, like CALL !-4.
If number=1, a power-on reset is performed.

*Go [<address>]
Branch the emulated 6502 to the specified address.

*OS
Provide a *-prompt loop within the 6502 emulator.

In the emulator the BREAK key emulates the BREAK key on the emulated
computer, but the RESET key resets Archimedes.

*Tape is provided (in case an application issues this command), but cannot
load or save files.

Econet OSWORDs are not supported.
