Here is schematic for DIDAKTIK GAMA 89:

GAMA 88 is very very similas/same. Only can contain bugs
As I know, in old DIDAKTIK GAMA models is bug in ROMCS signal on ZX bus. ROMCS is unusable and is impossible (and dangerous) connect any interface with external memory rom (DIVIDE, DIDAKTIK 40/80, INTERFACE M/P, etc...)
This is easy to fix:
internal rom select between ULA chip and ROM chip must be connect via resistor as in GAMA 89 schematic and signal ROMCS from ZX bus must be connect direct to ROM chip.

Old GAMA model can contain too long CLK line on PCB. For better stability is better disconnect ULA and CPU from this line and connect with new short cable.
