[rescue] Looking for an USII/300 module and answer to question about PN's

[Lionel Peterson]

I think you are in good shape with anothe r501-4849, never mind the "-03" or 
Rev 61 information.

If you find yourself concerned about this, I'd suggest buying a pair of 
matched 300 MHz CPUs and then sell your odd CPU. If 300 MHz wasn't the 
fastest supported CPU, I'd strongly suggest upgrading them - not becuse 300 
MHz is slow, but becuse 450 MHz CPUs are pretty cheap these days on eBay 
(great for folks with U60s and some U2 systems)...

The E250 is a great machine, esp. once yoou stuff the front with 1.6" SCA 
drives and add lots of RAM in thsoe 16 slots...
