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.

Documentation for SWIs supported by module MightyMouse v1.00 (04 Mar 1995) � Michael Stirling Edit work area = 77 MightyMouse_Buttons (SWI &5FFC0) FUNCTION Read or write the mouse buttons normal/swapped setting and their CMOS configuration. ON ENTRY R0 = new bits in field R1 = field mask Flags are ignored ON EXIT R0 = previous bits in field R1 = preserved V is set if an error occurred NZC are preserved INTERRUPTS Interrupts are undefined Fast interrupts are enabled PROCESSOR MODE Processor is in SVC mode RE-ENTRANCY SWI is not re-entrant USE Intended for use in a boot file or desktop management utility that wishes to swap the select & adjust mouse buttons for left-handed users. To allow the programming of individual bits, the call takes a field and a mask. The new buttons settings are: New buttons = (Old buttons AND NOT R1) OR (R0 AND R1) R0 = Old buttons R0 bit field definition: Bit 0 Read/write normal/swapped buttons state Bit 1 Read/write normal/swapped configuration status Bit = 0 Read/write normal buttons Bit = 1 Read/write swapped buttons Bits 2-31 Must be 0 for future compatibility To read a bit, clear the required bit in R1, the corresponding bit in R0 will reflect the current status. To write a bit, set the required bit in R1, the corresponding bit in R0 will be written. NOTE: When reading, the value of the corresponding bit in R0 is redundant. The call always returns the pre-modified states of bits 0 & 1 and preserves bits 2-31. Related SWIs: OS_Mouse Related vectors: MouseV **************************************************************************** MightyMouse_CmosAccess (SWI &5FFC1) FUNCTION Read or write the CMOS RAM ON ENTRY R1 = RAM location R3 = Value to read/write R4 = Mask Flags are ignored ON EXIT R0 = Original contents of location R1 = Preserved R2 = Modified contents of location R3 = Preserved R4 = Preserved V cleared: generates no errors NZC are preserved INTERRUPTS Interrupts are undefined Fast interrupts are enabled PROCESSOR MODE Processor is in SVC mode RE-ENTRANCY SWI is not re-entrant USE Allows the programming of individual bits in any location of the CMOS RAM, which the RISC OS SWIs 161 & 162 cannot do. Note that location 0 can only be read. This SWI was originally written as an internal function of the MightyMouse module, but has been given external access as it is potentially useful to other programs. To allow the programming of individual bits, the call takes a field and a mask. The new value is: New value = (Old value AND NOT R1) OR (R0 AND R1) R0 = Old value Bits 8-31 passed in R0-R4 are ignored and preserved across the call. To read a bit, clear the required bit in R1, the corresponding bit in R0 will reflect the current CMOS value. To write a bit, set the required bit in R1, the corresponding bit in R0 will be written. NOTE: When reading, the value of the corresponding bit in R0 is redundant. Related SWIs: OS_Byte 161 & 162 Related vectors: ByteV
