Is there a small JD manual for Plussy? Thank Posted By JamesC on 2017-03-09 13:14:38  Re: JiffyDos question There is no JiffyDOS manual specific to the Plus/4. We use the 64/128 manual: http://www.jbrain.com/pub/cbm/manuals/JiffyDOS/JiffyDOS_V6_User_Manual_(searchable).pdf Please be aware: not everything in the 64/128 manual applies to the Plus/4 version. You can obtain the JiffyDOS function key assignments through the Plus/4's KEY command. (This also works on the 128.) Simply type KEY to see the definitions; redefining the keys is as simple as typing KEY 1, "PRINT" + CHR$(34) + "COMMODORE" + CHR$(13) We do not know the SYSxxxxx for re-enabling the function keys, or to re-enable JiffyDOS. Personally, I prefer to reset the Plus/4 if I need to re-enable JiffyDOS. This can be done with SYS65526 (warm boot) or SYS32768 (only restarts BASIC).

I prefer redefining the keys through my ML program than doing it in BASIC. Back to top Reply to this topic Copyright © Plus/4 World Team, 2001-2024. Support Plus/4 World on Patreon
