Mac iifx Kingston 2MB 64 pin SIMMs?

[TimHD]

Found these Kingston 2MB 64 pin SIMMs in my Mac IIfx but it would not boot with them in the RAM slots.

I suspect the IIfx cannot handle 2MB SIMMs but if so, what machine/hardware are these SIMMs for?

Could they be the for the NTX?

I think laser printer memory was 100 or 120ns which is very slow. That RAM could be for a different machine (there are a few that use special 64 pin SIMMs).

I googled the part number and it showed as being used on an SGI Iris Processor board, albeit in an 8MB version.

Nicely done. Seems to be "proprietary memory" for that system...

No wonder the Mac iifx did not like it.

Perhaps the 8MB notation is referring to a set of four? Kingston (and others) often screen print or label a part number for the entire set on each module, rather than using a number specific to the module.
