Yes I agree (though see my estimation of slowdown in another mail).

perhaps you mean the TSR doesn't use VDI for screen output. Or do you
consider TOS' screen output (LineA) dirty, too?

I will add other methods of retrieving current time into Clocky as soon as
I get some time to work on it, I promise. For other programs using those
cookies we might just say "start DTCOOKIE before MiNT only" and also
perhaps "use that application under TOS/MagiC only, it's too dirty for
MiNT".

Anyway, I liked the idea of 'fast calls' to GEMDOS/X/BIOS that would allow
us to call at least *some* functions even from within an interrupt. I am
looking forward to the results of Konrad's and others work.

...still dreaming about code like
/* in interrupt */
if (Cookie('MagX') || Cookie('MiNT') >= 0x110) {
    Tgettime();
    Tgetdate();
}
else {
    /* use DTCOOKIE or another hack */
}
