The 2 meg SIMMS are full o' chips, the 4 meg SIMMS are only half-populated,

same on the 2 meg SIMM. I have a number of them, and I would rather
unsolder the old RAM chips and replace them than screw with the only set of
working 4 meg SIMMs I have.
There's a bug in the ASIC (according to SGI)
on the 64-pin
proprietary SIMMs which means you can use any number of 2MB
or 8MB SIMMs but only one set of 4MB SIMMs on a 4D/35 or
R3000 Indigo.
So, if I "upgarde" the 4MB SIMMs to 8MB SIMMs, I can put
in more than
one bank of "upgraded" SIMMs? Or is this bug speciffic to the 4MB SIMM
ASIC and the 2MB and 8MB SIMM ASICs are different? --
