I have finished wiring up the cable for the Flex card to the 99/4a expansion port.
I ordered one of the PEB extension cables from hello cables and verified it worked then I took off the male connector. Stripped the wires and mapped the pins to the wires.
This ribbon cable has each pair of wires twisted and has a plastic shrink wrap over the entire ribbon cable. Makes it stiffer than a regular ribbon cable.
Tomorrow I will make some final voltage reads on the PEB lower PCB and then see if I got it all right and the 99/4A powers up with the interface card in. If that goes well then I will replaced voltage regulators on a 32k card and try again and go into XB and see if I can see the extra RAM.
Report back then.
