What sort of calculations (fixed vs float), running what operating system
(BASIC, CP/M, Forth, HPL, HP-UX or Pascal) and on what CPU (68000, 68010, 8
or 12 Mhz)?

There is a 98635A floating point card available from HP, that is supported
by BASIC, HP-UX and Pascal.  The 12 MHz CPU upgrade may also still
available.

I have also seen adverts for Series-200-compatible 3rd-party 68020 CPU/RAM
boards running at higher speeds, but about these I know nothing, and I
suspect they only work with BASIC and Pascal.
