Title: Amiga 3000T Pinouts - anyone have em?
Post by: CatHerder on November 19, 2004, 10:46:53 PM: Does anyone have the pin-outs for the A3000T motherboard PS connector? I have a couple connectors and I can just make a new PS from a 200 watt AT ps (and fit it into the 3000T ps case) but I don't want to fry the mobo trying!

I can find pinouts for every other Amiga, just not the 3000T.

I'll be your pal. :-D

Post by: Jeff on November 20, 2004, 04:58:27 PM: I was gathering this together from a variety of sources years ago and it still happened to be laying on my desktop. Please help me complete it and verify it is correct before using it.

I DO have the factory service manual also if I can be of any other help let me know. BTW I have not cross checked this with the service manual yet (I have to find it :-)). I will correct any mistakes if I find them.

I did hack this together with a PC AT supply about a year ago to test a motherboard I bought on eBay from KarmannSS (SP?). The motherboard was destroyed by a previous repair attempt when I got it so it didn't work. However it didn't smoke anything!!

Thanks,
Jeff

Post by: Jeff on November 20, 2004, 09:44:35 PM: I'll find it alright :-). I just moved, so it might take me a little while so be patient. I'm going to storage to get my 060 A4000D tomorrow. I can't stand it anymore. I'll PM or post when I have the A3KT SM in my hand again.
