Hi all
I have HP Cpu board A2051-66501 with HP cpu inside, I was trying to find some info about CPU. It is 431 pin. I think it should be HP 7100LC. Google told me that it should be 48Mhz version but Iam really not sure because HP PA 7100LC should be running from 60-100Mhz - http://www.cpushack.net/PA-RISC.html
In the board is part called EX055P7E 96Mhz.
Any idea what it is? 7100LC 96Mhz?
Thanks for reply
Best Rgrds

I know no much about HP Risc.
But I guess it's 48MHz(96 clock rate divided by 2) cpu

The 96MHz-part is a clock oscillator,
all older HP-boards are dividing by two for
generating the CPU-clock so it should be really 48MHz.
This speed is a bit strange, OpenPA.net
also only knows the 60MHz-version as slowest.
But I think it is a uncommon PA-7100LC at
48MHz!
