  1. It turned out to be some superficial glue plugging the hole, no screw. I guess a previous owner tried to glue a threadless knob back on The glue didn't join very well to the actuator which made the removal easy once I knew what I was dealing with.
  2. Thank you. 👍 I was able to remove the old glue plugging my the actuator stem and screw in my reset button.
  3. This is really an excellent game and deeper than it appeared at first. I was hooked when Sinistar appeared.
  4. The picture looks fine to me. Is there something in particular you don't like? These are old analog machines, the displays have a little personality.
  5. I did order a replacement, it just doesn't fit. The replacement button has a post in the middle that doesn't fit the white plastic post on my Vectrex. I edited the original post to show my replacement button.
  6. My Vectrex is missing the reset button. It has a white plastic post where I assumed a nice button attached. I ordered a new button, but it does not fit on the post, it looks like the post is supposed to have a hollow center. Pressing the post resets the Vectrex, so the actual switch seems fine. Do I have a stock part, how is it supposed to look?
  7. There is the Vectrex IOS app that does all this except take physical carts.
  8. I've been messing around with this idea and am using a Teensy 4.1. It is Arduino compatible and has a built in usb host. Teensy 4.1 (pjrc.com)
  9. I put a very simple circuit together shorting pin 9 to 10 and 9 to 11 through 250K resistors. This puts the dot in Pete's Test Cartridge right about in the middle as expected. But the dot jumps around a bit, maybe in an area 5x the size of the dot. Is this amount of noise in the position normal or does it indicate a failing component? Is it possible to get a more stable reading?
  10. The way I understand the trackball workings is that the speed you roll it produces a variable resistance on the joystick wires. My question is how long of a period the movement is sampled. For example, if the ball is moved quickly for 1/200th of a second and then stopped, does the resistance remain high (or low) longer to make sure the game has enough time to sample it?
  11. Aren't the original pots 500K? I would think center should be around 250K
  12. Realsports Baseball is one of my favorite 5200 games, and my favorite baseball game on any platform. It uses the keypad for pitch selection, and the analog stick for bat swing and player selection. It is probably the worst 5200 game for a product like this.
  13. I'd argue to include analog control - let the 5200 shine where it can. It is already so limited compared to the arcade hardware. Vector Pilot is analog and would be worse if it was 8-way.
  14. That is a pretty cool product, I've never seen it before. The controller is missing the analog stick and the keypad buttons. A few games won't work because of that. For example, Star Raiders, Tennis and Baseball use the keypad during the game. I'm sure there are others. Most games should work well though, probably a lot better than with funky 5200 controllers.
