Jinks Posted March 7, 2015 Share Posted March 7, 2015 Ok so I finnaly have a few minutes to check out the 600xl of mine that has the u1mb and video upgrade installed and need some help. How do I use the u1mb? How do I use the sio2bt with ultimate it is set up for it but can not load games? Lets say for example how would one start missle command that is already on u1mb? For sio2bt I disable spartados and enable bt and then what? Totally lost.. not been able to try my atari for almost a month and have just tonight to try then busy for another 3 weeks. 3 hours of a blue screen and trying everything. Searching on google finds lreks manual that gives specs. I did find a user manual and posted it on here but hell cant find where the hell it went..

TheNameOfTheGame Posted March 7, 2015 Share Posted March 7, 2015 Press RESET while holding down the HELP key and the Setup menu will appear for U1MB. For missle command I think it is in the XEGS slot so you have to have one of those or rewire the cartridge port somehow. I've heard of it being done. You can flash things into the BASIC slot and OS slots if you want to have a game flashed in there, but there are size limitations. Use FJC's in-place flasher to do it. http://atariage.com/forums/topic/220750-in-place-ultimate-1mb-incognito-rom-editor-and-flash-tool/page-11 1 Quote Link to comment Share on other sites More sharing options...

jvas Posted March 8, 2015 Share Posted March 8, 2015 Sorry for hijacking this thread. I just wanted to install U1MB into and XEGS, but I ran into problems. This U1MB is from Candle, so it doesn't contain the necessary resistors of RD4 and RD5. I installed sockets for the OS and the MMU. With these resisotrs and sockets, the original OS and MMU works just fine. I took the four signals from the CPU. When I install the U1MB, I just receive a red screen. When I put the original OS and MMU back, everything works again. Is there anything else needs to be done in case of the XEGS? What does the "p3 (XEGS mode)" jumper do? PS. I sucessfully installed another U1MB into an 1200XL, and that still works fine. (with the guide of Sebastian, but it seems he is not really available nowadays) Thanks in advance! Cheers, Jozsi Quote Link to comment Share on other sites More sharing options...
MrMartian Posted March 8, 2015 Share Posted March 8, 2015 I had a similar problem when I first installed my Candle-built U1MB.. Turns out the EPROM wasn't programmed properly. I programmed it in a programmer, and away it went! Do you have another you can swap the ROM out of? 1 Quote Link to comment Share on other sites More sharing options...

Just didn't want to take it apart if possible. First I wanted to know, that there is nothing I missed in case of the XEGS. There is not an installation instruction for it specially, and I was curious about that "XEGS" jumper... Will try to replace the eprom and get back with the result. Thanks!

atari8warez Posted March 9, 2015 Share Posted March 9, 2015 (edited) I believe the XEGS jumper is there for using the board in XEGS mode. Which means being able to use ROMS other than the built-in Missile Command when you populate the other ROM slots. You can then select other games from those slots.

jvas Posted March 10, 2015 Share Posted March 10, 2015 Strange: the board, that is not working in the XEGS, works fine in the 1200XL. Please fin attached the screenshots of the installation. Can somebody find out what I'm doing wrong? Quote Link to comment Share on other sites More sharing options...
Roydea6 Posted March 10, 2015 Share Posted March 10, 2015 (edited) This wire was a posted fix for the original for fitting into the XEGS machine..

Look at this post::: http://atariage.com/forums/topic/192930-ultimate1mb-new-preorder/?p=2675721 Great, thank you! Will try that as soon as I got home. I just don't understand why was necessary to remove that PIN of the OS connector if it wasn't connected to anywhere.... Quote Link to comment Share on other sites More sharing options...
