Aidean or Aidean Mesia M100T or similar schematic

[mikeydee77]

Does anyone have a schematic or similar from this japanese brand from the 70s/80s? I am just curious as the one in front of me appears to have a few mods (or bodges) but I would like to compare with the original circuit. I found a reverse engineered M60 circuit which may be close and of some help but I did see a few obvious big differences.
