Has anyone come across a large schematic of an ATAS clone?

Hello fan 2 ALL I traded the ATAS computer from CHRV (with 48k brains ONLY!) On the board it says ZX-ATAS-1.5 01.1993 and stylized TA label (merged together). So the question is - does anyone have a diagram and installation for this unit? (I'll scan the board later)
