So, then do they not have a superior solution which could be adopted by
the existing HECNET?

Sure. They are welcome to join anytime. They know it. I've been talking
with them since before they came online, since they asked me for help as
well as permission to use by bridge program (which I think they've also
modified slightly).
Unless I remember wrong, one or two of them are also subscribed here.
I no longer remember the reason they didn't connect from the start, but
I'm pretty sure they had a reason.

Nope, they have different part numbers on the power supply and they do not fit (and are not interchangeable). Trust me, I tried. :)

I don't own a -90 so can't confirm that.

I tried some good old moly lubricant the guys use at the copier shop where
I work - it made a slight difference but not much. The bearing is
obviously shot. The fan is *riveted* into the power supply. What the
heck?

For now, I am running it with one fan, and it being only 60-65F in the
house (and the computer office) the VAX is not running hot. I removed one
of the drives, since I really wasn't doing anything with it. (it was a
pull from a BA356 canister) Looked half-height to me, although I do have
some smaller in size drives that I may swap in.
At some point I'm going to source new fans and then try to pry the old
ones out. Other than that when I had the power supply apart, no domed
caps, everything is quite clean (and even cleaner when I gave it a date
with the shop air compressor).
I have two 90's (not 90A's) in the closet I could press into service but I
really do not want to trash this 90A for just missing one fan.
Thanks for the responses all.

Lets call it for what it is - "legacy" is a term that people use in a
polite but derogatory manner to imply that the future direction they
prefer is not that which they view as the current direction.

One more diff: http://pdp-11.nsk.ru/~form/files/bridge/bridge-tap.patch
It contains my previous path for OpenBSD and adds support for OpenBSD/Linux `tun' interface, so you
can use it for SimH:
bridge.conf:

[bridge]
tunnel @tun0

pdp11.ini:

Grab it, compile and test. There are also some improvements and bugfixes there. Not that maybe you had seen them in real life, but never the less...
The file I wget'd is date 2010 and compiled to the exact size of the last version I was using...
http://www.update.uu.se/~bqt/bridge.tar
Is that right?
That sounds wrong. I just checked again, and the tar-file is dated today, as is the bridge.c file inside.
And your url is correct.
Check the file size. bridge.c should be 15897 bytes.
