Pinouts for the connectors.

GPIO

5v VCC, other pins named according to their 65(C)22 counterparts.
GPIO0-GPIO15 are PA0-PB7 respectively and CA1-CB2 are named directly after their counterparts.

Column 1 Column 2
VCC GND
GPIO0 CB2
GPIO1 CB1
GPIO2 CA2
GPIO3 CA1
GPIO4 GPIO15
GPIO5 GPIO14
GPIO6 GPIO13
GPIO7 GPIO12
GPIO8 GPIO11
GPIO9 GPIO10

65SIB Connector

For this connector I would refer to the 6502.org forum post for the 65 Serial Interface Bus here. However I will provide a pinout anyways.

Column 1 Column 2
CONF\ GND
CLK GND
MOSI GND
MISO +12v
IRQ\ +12v
SEL1\ SEL2\
-12v SEL3
SEL4\ GND
SEL5\ SEL6\
GND SEL7\

Expansion ports

These are all usable lines taken directly from the board or processor. To be used with the matching right-angled connectors so that they can be used similarly to PCI ports or the ISA bus in x86 family PCs.

*IRQ lines are wire-ORed together so must NOT be totem-pole outputs.
