Those who don't know what on earth the
MDOS is, I can silently whisper it is a DOS from slovak Didaktik 40/80 disk drives (and
Didaktik Kompakt, of course), which are hugely widespread between Czech and Slovak Speccy owners. It could be a little bit confusing for those of you, who have heard about
MDOS3 by Sweet, which is in fact a modified MDOS to use with
divIDE. Well,
MDOS 2.1 by
MTs is intended to use with an original hardware from Didaktik Skalica. That means you must program you own EPROM with MDOS 2.1 and replace the old ROM chip in D80/Kompakt. Sadly, it can't be used with older versions of drivers which use MDOS 1.0, because these devices are based on a different floppy controller chip. MDOS 2.1 can be used only on later versions of D80 or Kompakts (those which used MDOS 2.0 originally). It is because of the FDC chip limitations. This all sounds complicated, but if you own D80 or Kompakt, it's worth of trying because the 2.1 version brings tons of bugfixes and advantages for the former user of Didaktik storage devices. It be even used with a
divIDE if you have it connected together with D80, so your divIDE will behave like a superfast D80. MTs also made a great manual in PDF for that (in Czech, surprisingly ;-P). Everything can be downloaded over
here.
