[Coco] OT: Need help ID'ing old 30 pin SIM

[Jim Cox]

I'm currently scrapping out some hulks that were given to 
me and I have been trying to ID some 30 pin SIM's that I 
pulled off a 486 system.

The PN is: KM41C1000BJ-6

I have Googled all over and really haven't found any info 
that would provide the size of the SIM.  I believe the 
speed is 60 microseconds, but I am not sure (I'm a little 
rusty here)

Does anyone know of a good site that can help me ID this 
SIM.

Thank!

Jim
