And lastly, I'm confused about FFP. I am guessing that FFP required FP,
which is supposed to be standard on E series. But a few lines in various
docs make me think that perhaps older rev E series didn't have FP built in.
Some docs mention that when ordering FFP, you can specify option -100 to get
some additional roms, necessary for E series machines with a serial number
less than 21XX (co-incidence on the rev number). I'm guessing that the
additional roms are FP? The roms in question are:
Hi again
My understanding is that for the E series, the only difference
between the E and the F is the additional firmware ROMs. My
understanding is that you'd need the ROM expansion board.
I hope you are going to make some binary files of all these ROMs.
Maybe Al can make a directory to hold ROM images.

No, the E and F
series use different microcode - the architecture is
definitely different. Backwards compatable, but definitely different under
the hood.
I hope you are going to make some binary files of all
these ROMs.
Absolutely, unequivically :)

E's and F's use the same architecture!
Later revisions of the F series firmware 'packaged' the microcode
options differently, but the
basic E-series microroutines run exactly the same way on an F series.
What makes an F series an F series is a external floating point
accelerator box and ADDITIONAL
microcode to drive it. Then there is a series of microcode options that
are only available for
machines with this external box and internal microcode, options like the
scientific instruction set, etc.
There is no 'difference' to the CPU boards between E and F machines, its
just a batch of bolt-on
hardware and firmware ROM's.
