Is the BigBoard II the same form factor as the BB I?

Subject: Ferguson BigBoard revived!
I owned a BigBoard in college, but gave it away
when I moved from
Champaign
to Boston. It is a pretty cool SBC with
integrated single density
floppy
controller and video. A friend (thanks Bob) gave
me an old BigBoard
which
he had laying around a while back and I started
making it work
again last
night. So far, the crystal circuit was dead
(temporarily replaced
with an
oscillator until new parts arrive), an address
buffer was dead
(purchased
a NOS 74LS241 off the shelf at the local
electronics store, mounted
on a
piece of cardboard which is all faded from age),
the video drive
XOR was
dead (replaced with new 74LS86 from my stock
bins), and all the ICs
needed
to be re-seated in their sockets.
So far, I have the video section working and the board boots the
system
monitor, displaying the output on the overly tiny
3" diagonal CRT,
which
is the only monitor that survived my numerous
moves over the years.
I've
purchased a new-to-me monitor for use on this
board, but this tiny one
will have to due until it arrives.
The next step will be to attach a SSSD 8" floppy and if that works
with
some scratch floppies, I will try to boot the
CP/M system floppies
that
I got from Don Maslin oh so long ago.
I still have a couple of articles about modifying the BigBoard to
use a
double density floppy drive. I may have to try
that at some point
in the
> future.
