> Dear Sun Managers,
> I have seral SS10 machines and 3 different CPU types.
> The CPU types are: TMS 390Z50 (SuperSPARC)
> TMS 390Z55 (SuperSPARC)
> This information was gathered mostly from the info header
> displayed when the machine is first turned on.
> Also from that banner, I know that the machines with the
> 390Z50 & 390Z55 have a ROM Rev of 2.14
> The machine with the SuperSPARC II has a ROM Rev of 2.22

> TIA for *any* help you may provide.
