    I found the issue with Bounty Bob Strikes Back 800 Cartridge version.

     

    Awesome! Thanks for looking at that.  I've noticed something strange on Basketball as well.  Looks like the computer controlled player can't seem to shoot very well.  Looks like it could possibly be a timing issue of some sort since the player doesn't hold the ball long enough to take the shot.  Same xex works ok under Altirra.

    Make sure Stereo Pokey is turned off (Stereo Sound in the Sound menu).  I'm still having trouble getting the 800 cartridge version to work, but the 5200 cartridge works fine with Stereo sound off).

    I saw that thread too, but I was thinking that the lock up described was that the birds didn't fly.  The XEX I have that works under Altirra and the ROM from Atarimania both run the intro screen fine, but the game won't start.  Is that what you are seeing?  BTW, stereo pokey wasn't enabled on my install.  I'll see if I can find the 5200 variant.  Thanks!

    jc13 and I have been talking about this in PM's.  I'll do some testing this weekend, it crashed on him when the emulator was trying to open the SIDE2 CF image.  

     

    If you have similar issues, what I asked him to do is set the Ultimate ROM image in preferences when you have some other machine type selected, exit prefs, and quit the program.  Then restart and try setting the machine type.  He was able to get it working doing one image at a time this way.

     

    I also think it might be an Apple security issue.  I have given Atari800MacX Full Disk access on my machine, since I have all of my media images stored in the Applications folder, which is the way it has been for 18 years.   Apple really doesn't want applications to write to the Applications directory.  And one thing Atari800MacX does is create a .nvram file with the same name as the Ultimate1mb or SIDE2 rom image that stores the preferences for the device.

    Thanks to atarimac for pointing me in the right direction...  Got this working well, but ran into one other issue trying to get my favorite game Bounty Bob Strikes Back working.  I've seen other threads about problems running this under emulators and eventually found a copy that worked well under Altirra, but it seems to have an issue on Atari800MacX.  Basically it just won't start the game - the birds fly, but no response to keyboard or (emulated) joystick.  Anyone else care to give this a try?

    I have it running on Big Sur, but I'm seeing some strangeness with the os roms and directories settings occasionally changing to previous values.  Seems to be happening after I try to get the U1MB / Side2 expansions to work.  I'm not sure what I'm doing wrong there, but after adding the U1MB rom file and selecting an XL machine with U1MB it crashes.  I tried running the it from the terminal to see if I could get any additional output, but all I got was a seg fault.  Anyone else seeing this behavior?

    I hope everybody making devices takes note of this, it is a solid path forward for a connector that is not only very reliable (it has withstood hundreds of insertions and pulls with my current test board, thus far), it is also very inexpensive to make.

    Hey Thom - I was working on making one of these to play around with and haven't found a part number for the pins themselves - can you share that info if you have it?

     

    Thanks - John

    Hi,

    has somebody an VGate Plugin for the actual U1MB Firmware 3.02? Have an 800XL (PAL) with U1MB, Stereo and Sophia DVI Rev.C @1600x900. I want to get rid of the ugly vertical artefacts on the right side of the image.

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

    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.

    For your consideration:

     

    Ultimate's architecture is of the "field/user-serviceable" type. If you get bricked while flashing, you can pull-out the 512K flash-rom chip (top-side) and re-flash externally. If you need to upload new .JED file on CPLD / Xilinx, you can do that as well, right from the JTAG programming-connector (10-pins, top-side). If the battery dies, well, a bit more disassembly required, but replaceable (bottom-side). 

     

    HOWEVER, if you fit the board under the shields, you will have to ALSO remove them whenever any of the above needs to be performed. These shields need to be properly affixed back on their place, either by screws+bolts (my 800XLs), or by flexible flaps (I have seen those, and I would kill them if I could). This would make the disassembly process a royal annoyance, in general. About 11-12 screws, disconnection of keyboard, complete removal of MoBo from the case and final shield-disassembly...  without mentioning that, in the case of a CPLD update, you will need to power-up the MoBo all naked, so you get the right Vref level on Ultimate / Xilinx... and then put everything back in, in reverse...

     

    Therefore, you may consider installing it in a way that shields (still present) would not interfere with such maintenance tasks (unless, of course, you don't mind any of the above). Also remember that you still have to attach the ROM-socket ribbon (it is wider/thicker), which now has to travel a longer distance from the board-location you are studying.

     

    Some food for thought. YMMV, though.

    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.

    added pix

    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.

    Does anyone have any idea what the red connectors on the Sophia DVI board are called, or where to get them?

     

    I'd like to find a compatible, crimp-on style that I could put on my USB Blaster cable, so that I can use it with my Sophia if need be.

     

    Thanks.

     

     

    Here you go. I used a bench vice with some spacers to crimp them on.

    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.

    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.

    Nothing is missing; connectors where removed and hardwired. Bottom right was the dvi connector, bottom left the L+R audio inputs, i guess top right was the power supply.

     

     

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

    I saw the Monoprice item at the beginning of this thread, but this device is not really small.

     

     

    Here are some pictures of the Monoprice device installed inside my 1200xl with a scale for reference. This device resolved all of my issues with monitor compatibility and it works great, but I remember reading some reviews of the device where they had problems with audio not working after a while. So far it's holding up well.
