Undo the screw and show us the inside to be sure, but I'd guess it is a Concerto as others have said

Without a doubt Ballblazer. The 7800 has by far the best version if that game, and the on cart Pokey Sound is a brilliant rendition of the title tune. That is the reason I got a 7800 a couple of years ago. I am so glad I did. 2 player Ballblazer has become a staple game in this house.

Some years ago I installed a Sophia RGB alongside my Ultimate 1mb and Dual Pokey mods inside my A130XE. However the RGB VIdeo out solutions was the Ribbon cable poked out through the back of the case. Well I finally mounted it properly this weekend. Hope you like I have a Scart Video cable that has the DB9 connector for the RGB video and 2 RCA plugs for the stereo pokey. All in all with the Ultimate1MB, Ulimtate Cart and Lotharek SIO2SD I think I have every mod I would ever want for this machine. However I am always open to other suggestions so anything I am missing to really push this little machine into the stars?

Since I guess we all grew up in the 80's & 90's when you know games were plentiful and tapes were cheap. discs were more expensive back then, and a simple dual tape ghetto blaster allowed you to "Legitimately" backup your mates tapes for archival reasons! so for pocket money you could quickly double your game collection

Scramble is excellent It depends what I fancy playing. The Sam coupe is the first choice for Prince of Persia or Battlezone, the Amiga for slam tilt pinball, the Amstrad plus for Pang, the CPC for chase HQ, turrican has to be C64, for the A8, RGB, Yoomp, Jet Boot Jack, Pole Position. MSX2 for Columns, Ghost and puyo puyo. They all have best games. No one platform is king. Or my favourite.

Well the Amstrad CPC 464 was my childhood machine so I will always have a fondness for that. Beyond that I appreciate all the machines I have for what they are. And now I have a lot.... Amstrad CPC464, CPC6128, 464plus, 6128plus, GX4000. Atari 130xe, 7800 Commodore C128, C64, Amiga 600, Amiga 1200 MSX (Sony hitbit) and MSX2 (Philips NMS8250) Sinclair speccy 128k toastrack, Grey +2 MGT Sam Coupe Timex Sinclair TC2048 Acorn Electron, BBC Master 128k Compaq 486DX4 75mhz Sega, Sony and Nintendo consoles and handhelds etc Do I have a favourite.... No, at the moment I have my MSX2+ FPGA clone out for use.

Well. I bought my 130xe to play RGB a few years back. It is really good game if you like that kinda thing. Yoomp is much better on the original A8 (even better with dual pokey stereo) than the c64 port. Also pole position and jet boot jack are amazing games on the A8. Disadvantages.... The cost of collecting hardware for yet another retro system. Do I regret it.... Not in the slightest.

More than happy with my Concerto.

Yeah, I found the problem! The SIO Speedup setting in the SIO2SD was set too high by default. Slowed this down silghtly and flashed the firmware to 4.05 successfully. The U1MB now correctly shows the Stereo pokey and the software switch works again. Thanks everyone, it seems that the changes between U1MB 3.02 and 4.05 firmwares mean the PokeyONE is detected. My issue is resolved.

Can you, or anyone else provide some guidance on the flashing process. I have downloaded the latest 4.0 release from https://atari8.co.uk/firmware/ultimate-1mb/ but I cannot seem to manage to get into a state to flash it. The hardware I have available is..... My Atari 130XE (obviously) The U1MB is installed and currently has FW 3.02 an Ultimate Cart and a Lotharek Sio2SD with the ATR in the Sio2SD I get 'No Dos'. with the XEX uflash I have no mass storage to load the ROM files from. I am sure there is a trick, but I cannot find it LOL

Can you let me know what Firmware version you have on the U1MB. Maybe it is time for me to upgrade mine

OK so I have now got beautifully balanced audio on my PERITEL Atari 7800. Using the picture from the linked post (Included here too) I have done the following mods... 1. Desolder the Audio Pickup (Blue Wire) from the right hand leg of TA2 and attach it to the AUD marked solder pad 2. Desolder resistor CA2 and replace it with a simple wire link This leaves the 6.8k resistor in line with the TIA audio and no resistor on the Pokey audio, the 2 signals are mixed on the trace of the reverse of the board between the left hand points of the Wire link now in CA2 and TA2 and then sent on to the RGB board via the Blue wire. I have now also done this same mod in the same way to my spare A7800 which just has a composite mod board and I can confirm that the quality of the balance between POKEY and TIA is greatly improved on this console too. In all honesty this seems to be a very simple way to greatly improve the balance between the 2 sound chips. *ALTHOUGH* I have not tested it with a RF Modulator as I do not have an A7800 with this still in place.

Yep that link improved things. Looking at the trace on the board however it would be easier to just solder the blue wire to the AUD point as that is connected to the left most points of the resitors marked CA2 and TA 2 already. I am still going to tweak the resitor values however, as although the Pokey is now louder (Going through only one resistor and not two) is it still overpowered for my taste in Commando. I might get a couple of variable resistors in there so it can be tuned more easily in the future

Yeah, that is there... with both "real" Pokey's in the Simple Stereo V2 board it works correctly. I'd stick with that, but the PokeyONE does not fit in the Concerto cart case.
