Victor HC-90/HC-95 RGB Connector
Description
This connector is a 25-pin D-Sub and it's specific to the MSX2 Victor HC-90 and HC-95 computers.
The pinout is actually very similar to the RGB21 connector, but there are differences:
- there are 4 extra non-connected pins, whose utility is unknown
- the HC-9X doesn't have C-Sync & YS inputs nor video out, and RGB21 doesn't seem to have the same SYNC OUT
