OT: USB adapters for PCMCIA slots
Thanks guys, looks like I need to find 5V from somewhere. I have an old
computer power supply I was using for 12V testing, seems to me it puts out
5V as well, easily enough tested. It will solve the problem in the short
term at any rate if I can get the plug's pinouts straight.
