I really like old hardware, and I'm into the Plan 9 operating system,
so these are doubly interesting to me. Does anyone know where I could
obtain a 5620 terminal or its descendant, the gnot? The 5620 newsgroup
is shut down, and there doesn't seem to be much chatter about them at
all in the last 5 years or so.

Yes, that is unfortunate. I'll have SDF's TTY5620 on display at the
VCF X (computer history museum) in less than 2 weeks. I have one that
I am interested in selling, but based on the potential demand, I'm
considering putting it on ebay and just seeing how high it would go.

The 5620 and later versions were sold by AT&T Information Systems
so they're probably available
(particularly since someone already followed up by saying he's selling one).
If the mouse is not included,
it's a standard 3 button bus mouse with the DB9 Logitech pinout.
The red dome Depraz mice are still considered
the most comfortable mice ever made.
I think the metal ball was first (requiring a mouse pad),
then a plastic ball was tried for allegedly better grip.

The GNOT is probably harder to get.
I worked at AT&T IS for years and never saw one
(although I got a GNAT: General Network Access Terminal
at the Trenton Computer Fest. It's a Z80 based AMD3A work-alike,
part of the SPYDER network of GN* devices: GNOME, GNAT, GNOT).

I have a 730 MTG complete with Ethernet card and X11 R3 Cart.
I'd have to agree when the mouse worked they were awesome.
What they really needed was better keyboards.

ATT really made reliable gear, just couldn't make it available at a cost the
masses could afford.

As someone who collects vintage serial terminals *and* graphics
systems, this stuff is tremendously interesting to me!

My intention is to open a brick-and-morter computer graphics history
museum in Salt Lake City.

These would be really good items to bridge the gap between the era of
graphics terminals and the era of graphics workstations.

I'd love to talk swap/purchase with anyone that owns one of these...

The TTY5620 will be on display at the Vintage Computer Festival at the
Computer History Museum Nov 3rd and 4th. Stop by and play with it.

As far as the one I'm selling it includes a mouse (red), keyboard and
manual set. Its a Version 2.

Oh, I'll definately be coming by to see that. Will it be available
for poking and prodding all day long? More importantly, will *you* be
available all day long? I'm going to be splitting my time between VCF
and nanotech event and I'd like to make sure we synchronize.

As I recall, the prices for 5620s and 630s (and presumably 730s)
were competitive with other "high-end" terminals that didn't do
much beyond X3.64, particularly the large-screen models.

My impression at the time was that it was a failure to promote
the advantages in a way to attract customers. If I hadn't seen
Rob's Blit presentation at Usenix, I might never have found out
how useful these products really were.

Please keep in touch with me; although I'm not currently able
to part with any of my collection, once I get around to
checking them out and fixing them up I may have some extra.
It may have to wait for retirement, though (perhaps 11 months
away now).

Running layers (presumably on a 3B2), or just X3.64 mode?

Yes, it will be there up and running with its 3b2/500 host system
(ex sdf.lonestar.org) running SVR 3.2.3. That will also be available
via TELNET for folks in the know. There will also be the TTY5620 manual
set, so if I happen to not be around, please enjoy yourself.
