Jacques Posted March 9, 2021 Share Posted March 9, 2021 (edited) Hi Guys I have U1MB that wasn't ever installed (pictures), spent good few years in the wardrobe I guess, before I update the firmware with the newest one from @flashjazzcat, first I need to program Xilinx with new .jed (v3)? Any comment will be appreciated Edited March 9, 2021 by Jacques Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted March 9, 2021 Share Posted March 9, 2021 Install it first and see if the 'SIDE Hardware' setting is present in the setup menu. If it is, it's almost certain that the CPLD already supports the new firmware. 1 1 Quote Link to comment Share on other sites More sharing options...
Jacques Posted March 9, 2021 Share Posted March 9, 2021 Thank you for prompt reply, @flashjazzcat And IF the SIDE Hardware is there and I can update to new firmware, would there be any benefit of programming Xilinx jed v3? Should I also replace that AMIC chip with better one you earlier advised? Quote Link to comment Share on other sites More sharing options...

Yes: there was a bug in v2 which made only the first internal BASIC slot usable. Version 3 fixes that. 12 minutes ago, Jacques said: Should I also replace that AMIC chip with better one you earlier advised? You could do, since I found the AMICs to be short-lived. All the AMICs in my boards died and have been replaced by SST 39SF040s. UFLASH will support the AMIC chips just fine, though. 1 Quote Link to comment Share on other sites More sharing options...

Any comment will be appreciated This is the original version of the U1MB, can be identified by board color and lack of current limiting resistors beside the MMU connector, this version requires 2 resistors to be added. They can be on the Atari PCB, an adapter in the MMU socket, or in the MMU connection cable, otherwise the Xilinx PLD will be damaged. 3 1 Quote Link to comment Share on other sites More sharing options...

Good call, although it was a handful of cartridges which managed to send 5V over RD4/RD5 which would blow the CPLD (which was supposed to be 5V tolerant, until it turned out it wasn't). Definitely not worth the risk, though, so the mod should always be done. 2 Quote Link to comment Share on other sites More sharing options...
candle Posted March 9, 2021 Share Posted March 9, 2021 you just need a random one cartridge that does that (pac-man? why not!) and you're done, so i strongly suggest to add them 2 1 Quote Link to comment Share on other sites More sharing options...
+Stephen Posted March 10, 2021 Share Posted March 10, 2021 Nice and tucked into the ribbon cable. Question though - will this cause any issues if I were to plug in a newer model U1MB with the built in resistors? Quote Link to comment Share on other sites More sharing options...

This tells me that my old one is newer as it has the R8 and R9 resistors next to the MMU connector. I am waiting for sockets to arrive before resuming installation...

Jacques Posted March 10, 2021 Share Posted March 10, 2021 (edited) Thanks for pointing it out Guys with additional resistors. Indeed, I have them in the original U1MB set I bought years ago. And I find the solution with ribbon cable near the MMU connector perfect, much better than cutting traces near the cartridge connector, as originally advised in the manual https://web.archive.org/web/20170709155909/http://spiflash.org/node/18 BTW. SIDE cartridge should no harm without them? Edited March 10, 2021 by Jacques Quote Link to comment Share on other sites More sharing options...
candle Posted March 10, 2021 Share Posted March 10, 2021 no, it should not as for bf2k+ question, time will tell - it should not in most cases, but if some cartridges banks in and out their cartridge space rapidly, some delay might be introduced that will push things out of sync - but it would be hardware specific, and really rare if observable at all Quote Link to comment Share on other sites More sharing options...

So basically you cut all the even numbers, but leave one to connect to Pin 2 U1MB side. Since pins 8/10 are unused on the U1MB, according to the pinout you listed, only pins 4/6 should need to be disconnected. Quote Link to comment Share on other sites More sharing options...

I actually own and use SIDE1 (SIDE A? ?) for years in SDX mode and its partitions on CF Just initial booting up was started from SIO2SD, then it's used as typical HDD But surely now it can boot by itself together with U1MB.

Jacques Posted March 18, 2021 Share Posted March 18, 2021 While everything was working perfect to date, just tried flashing firmware that includes GOS, but for whatever reason GOS doesn't work on my Candle's "black" U1MB, I'm only getting some garbage on screen after attempt to boot to GOS. Any hint, please? And by the way, is "smaller" SDX in GOS firmware missing some of the stuff? Quote Link to comment Share on other sites More sharing options...

How do you go about installing this? Did you just flash the 512K 'ULTIMATE.ROM' file, obliterating everything else on the flash chip, or did you do something else? 2 hours ago, Jacques said: nd by the way, is "smaller" SDX in GOS firmware missing some of the stuff? Probably 'man' files; I don't find them much of a loss, but YMMV. Quote Link to comment Share on other sites More sharing options...

That's exactly what I did, reflashed it as a whole using ULTIMATE.ROM file. It flashed perfectly fine as previously used ULTNOGOS.ROM. The only issue with either ROM I experienced so far, is the crash when trying to run GOS. Can it be because of older .jed (v2, I guess, since there is SIDE Hardware)?

No: that should pose no problem at all, since the GOS is using the exact same banking scheme as the built-in SDX ROM. Make sure you have some extended RAM enabled, though; I'm not sure if the GOS will fail gracefully if it fails to find at least 64K of extended memory. 1 Quote Link to comment Share on other sites More sharing options...
Jacques Posted March 18, 2021 Share Posted March 18, 2021 (edited) Will try it again and come back, as I'm not sure of memory setting I did it with. Thanks! Edited March 18, 2021 by Jacques Quote Link to comment Share on other sites More sharing options...
Jacques Posted March 18, 2021 Share Posted March 18, 2021 Reflashed it all again, made sure XL-OS and 1088KB is set and now the GOS runs fine. Thank you @flashjazzcat for all the excellent firmware and software you program, it's incredible stuff of extraordinary quality. 2 Quote Link to comment Share on other sites More sharing options...

Side note: is there an alternative to installing the full ultimate.rom file? I switched to the 192kB SpartaDOS image when I upgraded to 3.10, but I can't find a standalone GOS ROM for Ultimate1MB in the U1MB firmware archive, and the GOS-ROMs archive appears to only cover carts.
