Does anyone know how a IIsi ROM SIMM is marked on the SIMM itself? Or a IIfx ROM SIMM for that matter? I have seen this list with part numbers: http://home.earthlink.net/~gamba2/os8_se30.html#SIMM

but are these numbers on the SIMM itself?

All I know is that the IIsi ROM is a 256K, 64-pin, 4-chip SIMM. I'm looking for more info with which to identify them, say if some hypothetical person had a number of various ROM SIMMS pulled from various hypothetical systems but could not identify them (and the hypothetical suspense is killing me)! Perhaps someone has a close-up picture of one?

Thanks for any info!
