Hmm. Thinking about it now you could remove both the Matt> regulators and drop the +5 and +12 lines directly to the Matt> MB. There are some instructions to this in http://www.funet.fi/pub/cbm/documents/projects/other/c64-with-12volts.

You'll also loose the 9VAC on the user port, but it shouldn't be that crucial, since not many user port devices should need it. Besides, the 9VAC output was replaced with an 9VDC output in some later models. You could maybe use a zener also there. -- Marko Mdkeld , http://www.hut.fi/home/msmakela/ Helsinki University of Technology, dept. of Computer Science
