Title: HELP!! In need of Tempest Header Pin Pinouts Post by: wmartin on October 22, 2016, 05:54:28 pm Hello All,
I have a Tempest that my son and I have been working on, along with many others, but I got a Tempest board stack and it didn't have the harness that connects the AUX board to the Vector board. I plan on buying one, once I find one, but until then I wanted to test the board itself even more. Does anyone know if the pinout goes Pin1 on AUX goes to Pin 1 on Vector and so on or if it's a different pattern. This is the 24 Pin on the AUX and Vector Boards. We already rebuilt the WG 6100, the AR-2, and PSU. I don't want to fry something because I wired the 24 pin connector wrong. It would mean the world to my son if we can get this game running. Title: Re: HELP!! In need of Tempest Header Pin Pinouts Post by: wmartin on October 22, 2016, 09:54:20 pm Figure this would also make it a little easier. I'm trying to find the pin out info for the j17 to j19 connections on the AUX and Vector boards.

thanks blake Title: Re: HELP!! In need of Tempest Header Pin Pinouts Post by: John's Arcade on October 24, 2016, 09:57:24 am He sells them for $17.50:

In need of Tempest Header Pin Pinouts Post by: wmartin on October 24, 2016, 01:13:17 pm Thank you guys very much, I did find a great schematic on crazykong. The schematic I had was almost impossible to read. I went on Elecktronforge website and it said he was only doing select repair/ order fills since he is so backlogged. I made a temp. harness by just soldering the wires to the pins for test purposes. If I'm reading the schematic correctly the pin are pin 1 on AUX goes to Pin 24 on the Vector and this pattern goes on like this, if this doesn't seem right to guys please let me know, I did plug the board in and all I got was Solid lights on the Ply select buttons, no picture, and the only sound I get is constant beeps. Voltages are correct going into the PCB's and I already rebuilt the 6100. AR-2, and PSU. I did notice that I'm getting 10V out of the X out test point and 3v out of the Y out test point, I remember reading this should be between -2 and +2v. Is that correct? Also, does anyone know if someone may have a Tempest board set for sale, I'm going to post that also on the topic looking for parts, I wouldn't mind having a spare and it would also help me figure out what's exactly wrong with my Tempest board set. Oh and a side note, I noticed my board was missing the A1 I.C. on the AUX board, I ordered a new one and didn't know if it was a chip that needed to be programmed?

Sort of, I was able to find a decent schematic I could actually read LOL. I just wanted to confirm the order. From what I can tell its Pin 1 on Aux goes to Pin 24 on Vector and so on. I have a second board on the way that has the interbaord harness with it. Just it's missing 7 ROM's no big deal as i have a ROM burner that just arrived today in the mail. :D I also replaced the 10K and 1 K Pot's on the Vector board. Kept getting 10V out of the X and Y out test lugs. |
