The Radius Thunder IV GX is a family of cards which are all identical
except for the amount of video memory they carry. So the 1152 is
just like the 1600 except the 1152 will only do millions of colors up
to 1152 X 870, whereas the 1600 will do millions of colors up to 1600
X 1200. There is also an intermediate card, the 1360, IIRC.
I think that you can actually use them in OS9 if you give up one of
the control panels. You get to keep acceleration, but you lose the
fancy pan and zoom and stuff like that. But that memory is vague and
may be wrong.

Like other members of the true Mac II family (excluding the IIvi,
IIvx) the IIfx can take up to 16 MB SIMMs. Finding them is the
difficulty. The IIfx uses a strange 68 pin SIMM which was only ever
used in the IIfx and one printer. The SIMM is still 8 bits wide like
a 30 pin SIMM, but it splits the Write Data and the Read Data into two
separate 8 bit busses.
I keep threatening to find the top of my workbench and build some more
16 MB SIMMs for the IIfx but I haven't gotten through the geological
layers yet.
