Hi,
You just need a special cable, not a new PSU
Can be bought from A.Sys. directly; not cheap (15 E or so)
I think they could also be made quite easily as a DIY project,
especially if you have the original A.Sys. cable at hand.

Also, remember that the modules will not line up exactly with the A-
100's, as the mounting holes are slightly shifted in position.

regards
Joost
