Besides, the 16-bit PS/2s are 16-bit MCA, not 16-bit ISA.

IIRC one of the differentiators between the 25-286 and the "proper"
16-bit 286 PS/2 was the 8-bit expansion bus.
I had the bright idea of swapping out a Model 25 board (8086) with a Model
30-286 board, thinking that the boards were exactly the same. They are,
actually, but the Model 30 board comes with a three-slot ISA riser, which
does not fit in the Model 25 case.
Apparently I need the Model 25-286 two-slot riser. I don't want to try
plugging the original 8-bit Model 25 riser in, I fear it will somehow fry
the board.
Even the 25-286's riser is 8-bit isn't it? It would surprise me if it
wasn't compatible with the 25's riser.
