How would YOU equip SADF in the 1980's?

Agreed. In a large and multi ethnic country with a history of social fracture, anything that forces absolute majority of voter supported coalition is probably a good thing.

FPTP/unproportional parliamentary systems without coalitions seem to work well enough in stable or homogeneous polities. I'm not so sure they do so well in most other cases

The problem there is that proportional representation systems invariably end up causing political instability in a nation as fragmented as South Africa, and that invariably adds to the prospect of civil unrest, which in a nation recovering from apartheid needs to be avoided at all costs. I went with the seats for all races setup in the upper house for the reason you mentioned above, forcing a coalition. In this case, the bottom house will be invariably ANC majority and NNP opposition for all of the 1980s and probably the 1990s as well, with the upper house being a crapshoot.
