Re: JiffyDos question

Thanks for the info James

I could find the addresses on the KEY command page : http://plus4world.powweb.com/kb.php?id=500049.

I prefer redefining the keys through my ML program than doing it in BASIC.

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).

JiffyDos question

Hi,

What are the zero page addresses used as pointer to the JD function keys definition ?
on C64 and VIC20 they are $b0 and $b1 but not on Plussy it seems...

and what are the SYS xxxxx to re-enable the JD function keys and to re-enable the JD Commands ?

Is there a small JD manual for Plussy?

Thank
