That's true of the VT52, however the logic in the VT62 is completely
different. I don't know anything about it, but just looking at the
logic board you can see that it's not even close to a 52. I've no idea
what's in the 62.
I am pretty sure the VT62 is "more of the same". No hardware in
common, but a similar overall architecture. I could be mistaken,
however, and would love to know more, but information about that model
is very tough to come by.
I suppose it's remotely possible that the VT131 speaks the same
protocol, and it's documented. One could try based on that...the worst
that could happen is that it won't work, right?

We know. ;)
CP/M + VT100 in one box = cool :)
Extremely.
You could maybe talk me out of one for the right swap, maybe, but
you're on the wrong side of the water and I'll not be packing up one of
these.
Also would love one of the ReGIS/SIXEL capable boxes too..
VT240, VT330, VT340. All are glorious, and all are here.
Too bad I'm travelling so much now, have to tone down the hardware collecting..
That's a problem that can be solved.

Got documentation on how to talk to it??
Sadly I do not. They make use of a custom CPU, or perhaps just a
state machine. Got prints?
It might be too smart for us :-)
Nonsense! B-)

I'm pretty sure "not" - maybe you're thinking of a VT102?
VT102 doesn't do graphics either.
Maybe the two of you are thinking of the VT55 and VT125, respectively.

Where did you read that blurb about a PDP-11 OS (RT-11?) doing graphics on a 62?
Some random PDP-11 page, but I was clearly remembering wrong, VT62 is text-mode only..

What can be done (non-destructive suggestions only, please) with a
VT-62? This is NOT a VT52 (although it looks like one). The VT62 is a
block mode terminal that, I think, actually speaks DDCMP. AFAIK it's
incapable of being a plain ASCII terminal unless there's some hack I'm
unaware of.
Right now the only thing I can think of is to part it out as spares
for my VT52. I have two of the latter and it looks like at least some
of the major assemblies - CRT, keyboard, power supply - are identical.
I hate to do that, though, if there's a better use for it.
I would write something cool to take advantage of its strengths.
BTW, I received the KA820, thanks!!

I'm game if there's any documentation on its protocols..
They were made for the TRAX PDP-11 OS and I think they're largly undocumented. If somebody has a manual (other than the "how to plug it in" Owner's Manual, that is) I'd love to get a copy.
