Variants

Version	Source	Details
ROM 3.0	MGT	Source code on github. There are apparently 2 versions of ROM 3.0 in the wild: The original had ‘plc’ in lower case on the Splash screen, another one had ‘PLC’ in uppercase. (from Edwin Blink)
ROM 3.1	MGT	Has ‘PLC’ rather than ‘plc’ but that (and the version number) is the only difference. Listed at http://zxspectrum.it.omegahg.com/MG.htm
SC_Autoboot	Steve Nutting	Amended V3.0 with fast reset and ‘Instant F9’
ROM 3.5	West Coast Computers	Used in the Sam élite, a V3.0 with a new copyright message, replacement of keyword “DIR” with “CAT” and spelt ‘disk’ with ‘c’
Homing PROM	Simon Cooke	V3.0 with a custom-orderable copyright message.
HD Boot ROM	Edwin Blink	V3.0 with code to boot from ATOM Hard drive’s boot sector.
Trinity Boot ROM	Colin Piggot	V3.0 with code to boot from Trinity Ethernet Interface EEPROM.

Hi Hans,

This sound like a good cause. So:

I hereby allow all my SAM CoupÃ© titles (including ROMs) and associated manuals to be freely (re)distributed.

Tips

The current ROM version can be ascertained by typing PRINT PEEK 15 and dividing by 10 so 30 is ROM 3.0.
