  1. Let's build a Vector VGA

    About 5 months ago I started working on a Vector VGA replacement. I'm still many months away from being done, but I'm at a point where I have something to show. Inspired by DirtyMcDingus's "Let's design some POKEY replacements" thread, I decided to post progress so far. It's likely that as I get...
  2. Help identifying a board

    Can anyone identify this pcb? Context: There is a multi Williams near (ish) me. The cabinet looks in decent shape and the monitor is original. However, it had a weird mix of games on it… including moon patrol, Tetris, and a bunch of others that I don’t believe are on the jrok. This is a pic...
  3. AR-II 5V too low (4.3ish) and not adjusting

    Background: I'm a dumbass and accidentally swapped J6 and J9 while doing some bench work. I sent 36V ac into 5v side of the ar2. F4 and F5 immediately blew on the brick. When I started repairs, the full 10v3 uneregulated output was showing up on +5v output. I pulled Q2 and Q3. They actually...
  4. Question re expected voltages of an atari color vector power brick

    I picked up a used a037395-a (color vector) power brick and am testing it outside of a cabinet. Below are my expected and measured voltages. I am just plugging it in and testing directly on the bench. My non-digital electronics knowledge is fairly weak, so I'm not sure if the high dc voltages...
  5. New in Norcal (recent tempest pickup + working on vectorvga and multivector)

    Hello! tldr: I'm a new member from northern CA. I'm a semi-retired software eng/manager that has been on an electronics and retro arcade deep dive lately. I recently picked up a working tempest cabinet that needs some minor tuneups, and I'm starting to work on a multivector setup. longer...
