Not the latest found actually, Grabbed this unusual beast from eBay last year
The seller apparently was not very familiar with the vintage mac and he sold a lot of other vintage pc as well
From the pictures shown on eBay
a 9600 PM labelled as 200Mhz but...
the motherbroad from the picture was clearly a Kansas one
I was expecting at least a 350mHz 604ev
I didn't ask further as the price was right and it looked pretty clean inside.
On arrival, I opened the case and found the CPU daughter card labelled as engineering sample with no mention of the actual speed.
It freezed every now and then but ran rock solid once I added "new" ram to it few months ago
