  1. As some of you may or may not know, Thomas Jentzsch and I have converted some 2600 games to use a Trak-Ball controller. Thomas originally converted Missile Command to use the trackball over a decade ago. More recently Thomas converted Centipede and Reactor. I joined the fun and did Millipede. The thread we posted the ROMs in wasn't really related... it all came about kind of spontaneously. That thread does contain a whole whack of routines if anyone is ever interested. It all starts on page 4 and goes for several pages. Here in this thread are the latest ROMs, organized, for easy finding. Note for CX80 Trak-Balls: Atari CX80 Trak-Balls work the same as the CX22 Trak-Balls. However, some retailers modified the CX80's to be compatible with the ST Mouse (Atari Mouse). If you have a CX80 then you will have to try both the Trak-Ball and Atari Mouse ROMs to see which one works with your Trak-Ball, or try the detection ROM. It is believed only a small number of Trak-Balls were modified. Note for CX22 Trak-Balls: An early version of this controller only works in joystick emulation mode and cannot be used with these ROMs unless modified. Check for the presence of the "joystick/trakball" switch on the bottom left side to ensure that you have the later compatible version and set it in "trakball" mode. Wico Command Controller Trackballs: These trackballs don't work with these ROMs as is. However, the Wico Trackball can be converted to work. See modification guide below for details.

  2. I have developed an "upgrade" kit to allow playing 2600 trackball games with a 5200 Trak-Ball. The process just adds another cable to the controller and uses another "configuration cable" to link the original 15 pin cable with the new cable. Terminates in a 9 pin that plugs into a 2600 controller port. No permanent modifications are made to the trackball. Everything is 100% reversible. Works with the slate of 2600 games recently hacked to support actual trackball controllers. Following the success of one kit being installed by an end user, I'm just wondering if it's worth the effort to order in parts to make a few of these. PM me with inquiries.
  3. I got this from ebay yesterday. It was listed as untested so I'm not really surprised that it has an issue. After taking everything apart and thoroughly cleaning the inside, I've determined that the issue is most likely the vertical photo sensing module. Does anyone know a good source for buying one of these? This site seems to be out of stock. Better yet, is anyone here able to do this for me? I'd mail you the PCB only to keep shipping down and you would replace the vertical photo sensor, test, and ship it back to me? That would be awesome. I am a terrible solderer. Thanks!
  4. After having done some successful Trak-Ball hacks lately, I wondered if adding paddle support might be possible too. Both have (do they?) to be polled during the kernel, but I found that the Trak-Ball polling is surprisingly tolerant to irregular timing. E.g. if you poll every 8th scanline, no one will notice, if you skip some of those polls. And it doesn't matter where you skip them. So you can poll in 8,16,32,40 and then in 8,24,32,40. The intervals do not even have to be identical. A poll e.g. in 5, 14, 31 and 39 would work too. And since my hacks only poll during the main kernel, skipping a big number of scanlines is still not noticeable. I haven't tested this, but probably polling outside the kernel a number of times with not too large gaps between the polls would somehow work too. You do not have that flexibility for paddle polling. There the timing has to be very strict. And the kernel is the only part of the code, where you have such a timing over a longer period. I think most of the Trak-Ball flexibility results from relative positioning based on the previous position, where in case of a paddle, we start from scratch with each frame. So as of now, it seems that adding paddle support to an exiting game is much more complicated than adding Trak-Ball support. But maybe some of us can come up with some new ideas? E.g. can we do relative positioning with a paddle? Awaiting your input...

  6. I was just wondering if anyone around here knew what to look for to determine whether or not a CX-80 Trak-Ball had CX-22 internals? Is there any way to tell from the outside of the box if you were to buy one brand new and still sealed? If not, what should you look for when opening up the Trak-Ball housing to determine whether you have CX-80 or CX-22 internals inside it? Any advice would be greatly appreciated!
  7. From the album: Hardware

    Not mine. This is Dan Kramer's legendary custom 3-Fire Button Trak-Ball Controller built in Atari Inc's Consumer Engineering Division. This was used for playing the in-house "3-Base Missile Command" game for Atari 8-bit computers. Dan and others built several custom Trak-Balls there that weren't meant for the public. This one was unveiled at the 2015 Davis Atari Party.

  9. I was planning on picking up a CX80 Trak-Ball from Best Electronics earlier this week, but found that they were sadly out of stock. If anyone here happens to have a CX80 that's still new or in like new cosmetic condition that they'd be willing to sell then please do let me know. I can pay via PayPal. Edit: Trackball acquired courtesy of a very generous AtariAge member! That's all folks!
  10. Hi everyone, I was in need of a couple of CX22 replacement fire buttons, so I contacted Best Electronics and found that they are "down to the very last of them". As such, there is a limit of 2 per customer. If you own a CX22, you better act now, as the shaft on these buttons tends to break over time, from normal play. BTW, my transaction started with an brief email request and concluded with a 5 minute phone call. Everything was handled over the last 12 hours (Brad actually responded to my email yesterday, Sunday, which I was not expecting ) and the entire transaction went very smoothly, which has always been my experience. Say what you want about their website, but IMO, Best is still the best!
  11. Hello, new forum member here. I was perusing the 2600 Controller list, and I happened to notice that the listing for the Trak-Ball is really lacking. There is no info whatsoever about that particuler controller, and not even a picture. I happen to have a Trak-Ball that came with a small collection of 2600 stuff that I believed belonged to my mother(I'm not entirely sure who really owned it...). As an owner of a Trak-Ball, the appalling lack of info left me confused. Does that mean its rare? Hard to find? A complete mystery? What? Also, I would be quite glad to submit pics of it that can be added to its listing for completeness.
