That means you have software version 8 on the main processor and
rev 2 on the microcontroller on the analog side.

Highest I've heard about are 9 & 2.

Opt 1 is just extra (volatile) RAM, a couple of standard RAM-chips will
do that for you, if you think you need it.

The six vs. one eprom is just that: one big instead of six smaller ones,
the functional change is the contents (typically rev8 vs rev9)

I don't know if rev9 can be put in 6 eproms, but I suspect it could,
if somebody sends me a dump (do it via HPIB) I'll be happy to find out.

Never attribute to malice what can adequately be explained by incompetence.
