I believe that it is not used in the HP 6S (either version) or 30S.
It appears that these models are OEM'd by HP from another vendor,
although HP won't comment on it.

I don't think it's a Saturn. ISTR that the Thinkjet uses the same 8-bit
CPU core that's buried in the 71B HP-IL module, and several other HP
devices from the same timeframe. There's very little information
available about it.
