Hello fellow sun-managers,
SUMMARY of original query (Tue, 19 Jan 93 11:59:32 EST):
>Does anyone know whether or not the hostid prom can be swapped between a Sun
>SparcStation 2 and a Sun SparcStation 10/41 ?
********************
The answer is NO.
********************
The hostid proms are apparently neither mentally nor physically compatible
between SS2 and SS10 machines.
The first (2 or 4) digits of the hostid encode cpu type. The SS10 hostid
prom has 2 more pins than the SS2 one.
Thanks to the following individuals whose replies arrived here before

Exact guess as to WHY! The software is licensed Sun compilers/tools. The
license server is due to be upgraded from SS2 -> SS10. The vendor is Sun :)
They allow licenses to move between hostids twice per year and 5 times per
lifetime (of the software ?). After that, nobody (at Sun) knows what
happens (buy the package all over again?).
Thanks!
