This is great information.  Thanks!

Just checked the DELQA printset which gives the following for the
20-pin BERG:

1 Power
2 (key, pin blocked)
4 Power Return
6 Receive +
7 Receive -
10 Transmit +
11 Transmit -
12 Shield
14 Collision +
15 Collision -
18 Control out circuit A
19 Control out circuit B
20 Fuse OK

which seems to agree entirely with the DEUNA information you
have.  This is good news!

Okay, very nice to know this.

That would be great!  I don't think there is any particular urgency,
now that I have the BERG pinouts, but I'm sure the community
at large (and me) would appreciate having that online somewhere
in the future.

Many thanks!
