Shift838 Posted December 2, 2022 Share Posted December 2, 2022 (edited) i know a couple of different connectors have been used on the 99/4A to connect the internal power supply to the actual TI-99/4A main board. I am looking for a part number for the one in the photo, for both male and female options. Anyone know what it is?

The connector used in the TI is a fair bit smaller (but that's hard to tell from the photo) and the chamfering on the corners is different.

Also, they suck. If you don't cut the pins off of the strips just right, the pins will push all the way to the connector opening. Quote Link to comment Share on other sites More sharing options...

Shift838 Posted December 5, 2022 Author Share Posted December 5, 2022 I do believe it will be the .062 versions. I have found the below out mouser and based on my dial caliper they seem to be accurate. 03-06-1042 Molex | Mouser 03-06-2042 Molex | Mouser These are the mating pairs. I am going to get some ordered as I need to put in an order any way. 2 Quote Link to comment Share on other sites More sharing options...
