k-rite Posted May 19, 2005 Report Share Posted May 19, 2005 Hello there, I'm a newbie to midibox. I've been looking at all types of documentation trying to understand how to power 1 MBHP Core & 1 SID. I'm trying to do just the very basic setup to learn a bit.The way I understand it is, I can take 5Vdc from the C64 PSU to J1 on the Core and 12Vac from the C64 PSU to J1 of the SID and both circuits will be powered? Do I have to connect power to anywhere else? I was looking at the schmetic of "how to connect a C64 PSU to the Core and SID" and I just got confused with all the different power connections. The schmetic shows two switches, can I just use 1 switch?Anyhelp would be greatly appreciated.
