CON-SUP Connector
This page was last modified 01:59, 6 July 2021 by Gdx. Based on work by Mars2000you.

Description

The CON-SUP is a 60-pin IDC connector located on the Mitsubishi ML-G1. It seems to be an option unused by Mitsubishi. It is not soldered while the same connector on the corresponding Japanese Mitsubishi ML-G10 is soldered.

Pinout

CON-SUP connector pinout is reversed compared to the normal BUS expansion. Pin 1 is on the right instead of on the left.

  • Pins 32-36 are buffered outputs, connected to v9938 through a 74LS244 chip.
  • Color bus buffer direction is controlled with v9938 CBDR pin.
  • Pins 53,54 are connected to v9938 through a transistor to switch input or output.
