Weird 72 pin 32Mb simms. They look like they were pulled from a server but have a configuration I've never seen before. 10+2 chips per side.



They fit and are recognised by my CS MKII
Not sure what speed they are. Some chips have a 6 suffix & some 7 (60/70ns?). Will do some testing.

I have 10 of these

Figured it out:
HM5117400AS6 x 16 @ 60ns = 128Mb
HM514100CS7 x 8 @ 70ns = 32Mb (i.e. parity)
