Here is his response on the MK1 turbo:
Chris,
If you look closely at the picture on the site,
there appears to be an additional daughter card for this hack
http://www.vm68.com/mkromhacks/Kombo1.jpgAssuming I can find the correct eprom image to program,
without this daughter card, I doube very much it would work.
If you want this turbo upgrade, I'm afraid you may have to buy a PCB
that already has this hack.
Sorry....,
Steph
