Update has a bunch with cracked flybacks. I did find an
Italian(?) reseller of replacements but we mever got arround
to ordering.
I could search for those old emails.

Will do next time it's not working. It decided to work again.

What're the differences between the two again? I have a DEUNA for my
11/44 I still need to get rolling.
The DELUA is one board, while the DEUNA is two, I can tell you that much.
Right. In addition, the DEUNA have a PDP-11 at the heard, while the DELUA have
a 68K.
An -11 powering the NIC for a bigger -11. neat. ;)
So, at the microcode level, they are totally different.
The DELUA also have a better ethernet controller (a LANCE chip).
In short, the DELUA is improved in most ways. But it's fine details.

Hello!
The last time I had a monitor throw a spanner into its flyback, and
this was a long while ago, when I found out why they need them, it was
a problem to find a new one.
Then since the first repair firm fouled it up, the second stuffed a
generic inside and it continued to work for many more years.
(Actually they looked up what was the designated non manufacturer's
replacement number for it.)
Cory see if the blasted thing has a serial number on it, and ask
Google. Worse thing that can happen is that the example will be
unknown to it.

My VT320 decided to fail last night.
It was running fine, I stepped away, returned to it off and repeatedly
clicking/ticking. It sounded like either a stuck relay or the flyback
arcing. The screen would occasionally flash and the current draw would
fluctuate between 2W and 17-25W until it eventually turned on and ran
fine.
Any theories? Should I distrust the VT320 or was it just something like a
stuck relay that's older than me? I grabbed pictures of the board but
they never seemed to actually get anywhere.
