  1. I have it updated, but am traveling at the moment. I’ll post it as soon as I get back to my computer.

    Thanks for checking - I was able to create the couple of parts I was working with, so no need to go through backups!
  3. Got it - thanks for the quick response!
  4. I don't have any particular application in mind, but I was curious if it was possible to control the S0/S1 (or M0/M1) lines from within the OS or BASIC (i.e. outside of the U1MB setup screens). I'm guessing there would need to be some sort of driver/handler to do this, but couldn't find an answer.

    Hello Ivop - if you still have this and it's not too much trouble, I'd like to get a copy of it if you don't mind. It seems like it may have been attached to the post at one time, but I don't see it anymore. Thanks - John
  6. Thanks for the feedback on this - all valid points. Not sure if all 600XLs are like mine, but it really wasn't too bad removing the shields - the top/bottom shields were held together with the bent over tabs you mentioned and maybe 4-5 screws holding it together and to the bottom case. At any rate, I already had it in my head that I wanted to try to get the shields back on and it actually worked out pretty well. The main issues were getting the vertical headers for the MMU cable low enough, having the older U1MB with the right angle headers so I didn't have to desolder too much, and replacing the vertical header with the HALT/RESET, etc. signals to a right angle header and flipping it to the underside of the board. As you mentioned, I needed a longer cable for the ROM adapter, but it all went back together pretty easily.
  7. I was just working on this today and this is my planned location (RF modulator spot). I pulled an older U1MB from my 800xl that had right angle headers and swapped the smaller connector (at the back) with two rows of vertical pin headers (with the plastic bit underneath and the pin height adjusted so the connector made contact properly. As others mentioned, removing the strain relief on the connector was also required. I need to figure out another support standoff or two, but it looks like this might fit completely under the RF shield. Also, I'll likely have to modify the headers for the HLT/Reset, etc. lines since the supplied wires will stand too tall.
  8. Here you go. I used a bench vice with some spacers to crimp them on. http://atariage.com/forums/topic/274004-sophia-revc-dvi-board/page-7?do=findComment&comment=4097750
  9. Another BTW, the jumper setting image on page 3 is reversed, but otherwise a great compilation of all the info scattered about. Thanks!
  10. This was the forum post I followed to test mine - you basically end up bridging two pins on the 4050 which basically bypasses it... I still went ahead and replaced the 4050 - they are not expensive at all. http://atariage.com/forums/topic/139202-6-switcher-left-player-always-firing/?do=findComment&comment=1683197
  11. Like Banquo said above, I’ve had this happen on a few 6 switchers and it’s likely the hex buffer (CD4050) that’s failed. There was a workaround that you can use to verify and you could leave it like that or just replace the chip. Sent from my iPhone using Tapatalk
  12. New internal pics added by request.
  13. I have this one, but I'd have to unbox it to get one inside the shielding and I'm not at home until tomorrow.
  14. Hey guys - I'm cleaning out some things from my "80's closet" and I've put a really nice heavy sixer out on Ebay with a good assortment of games. When I picked this console up a few years ago, I did the caps, voltage regulator, and new switches from Best. Come check it out if you are interested. Sorry - I'm having trouble with the bbcode link not working, but the full auction link is below.

  15. That is correct - only the bulky connectors were removed to allow for an internal installation.
