Comments on installing video board

[3673,ATTT]

good morning netland!

just received brian botton's video display board.  nice job brian!
just one small question: why did you use the socket pins and
have us bend a pin out on the 68010 instead of using a second
socket underneith the daughter board? clearence?  i may be looking
into a small board modification to allow this.

i haven't started the video board yet, but last night i did
install a WD2010A on the motherboard.  i used brians instructions 
on "how to open up your 3b1" and have the following observations:

NOTE:
my motherboard was a "REV B" (white sticker in front right
side on motherboard) with 2MEG unsocketed ram.  no
whitewires on the top side.  unit has one fan.

(1) when removing the second plastic cover (after pulling
the monitor off the top) check the power connector on the
floppy drive.  it may need to be disconnected to avoid
interfering with this removal.

(2) also, prying lightly with a screwdriver (small) under
the front edge of the plastic shell helped detach it and
get it moving.

(3) if you want to make work much easier, go ahead and
remove the top board (with the drives and power supply).
After you get the plastic shell off, disconnect the red and
blue leads from the power switch.  disconnect the fan,
(fans?) and detach the green ground wire.  my ground had to
be unscrewed at the powersupply end, since the connector
was soldered onto the switch :-(  lift up the front on the
metal cover and disconnect the three drive cables from the
motherboard. now you can remove the top board and set it
aside.  this made working on the motherboard much
easier. (especially removing chips) 

otherwise, the operation went very smoothly.  thanks for the
very good documentation, brian.

one further question:

on the front right side of the motherboard, right next to
the volume adjustment, was a piece of plastic with a bunch
of pins attached to it.  this was inserted into a socket on
the motherboard.  it looked like about a 24-pin socket.
brians figures have this position labeled as "network
communications" or something of that sort.

what is this for (or was it for, considering there's
nothing there)?

thanks for the help
