We tried to retrofit a bog standard style but could not get it to work. This is over 13 years ago so my memory is fuzzy on what we did. Who knows? a good sparky might be able to sort it.
We bought the retrofit kit for the cards and had Heidelberg install. FWIW ours came with 4 cards, who knows what they come with now. I wish I had more info but that press is long gone... shipped off to India.
I'm sure Heidelberg still has the kit available $$$$
