(edit) Is a modded MT-32 with an extra 4 outputs still play the same from the original two outputs for dos gaming or is the reverb different, does anyone here have/used a modded MT-32 with the extra trim pot to reduce noise and is there any complaints you know of when using a modded one for games?

I have a Roland MT-32 that I need to identify but I need help to do it, it looks like its an old version as it does not have a headphone jack but it also looks like someone modded it with an extra 4 outputs but since I have never owned an MT-32 I could be wrong but it is not mentioned in the MT-32 wiki, I would like to know how to see if the ROM is an old version and not a version 2 (newer with headphone jack) in an old case but I dont know how and what to look out for on the PCB number to identify if its an old or new one too. I have two pics to show the modded outputs and that from what I see that looks like bad track repair and if people here can tell me to go ahead and buy this MT-32 or to stay away from it. I need to give instructions to the seller how to press the buttons to identify the ROM version and whatever else to look out for to fully know what is what, hopefully its a version 1 original.
