With the addition of two more Tektronix 4015-1 terminals, I've
rearranged my Tektronix storage tube terminals in the warehouse and
uploaded some updated pictures of "Tektronix storage tube row". (The
4015-1 is essentially a 4014 with APL and printer interface options.)
Neither of the 4015's are reported to be in working condition from the
seller, but at least all the keycaps with APL glyphs are present. The
4010 and 4014 are relatively simple terminals, so I should be able to
restore them to working order. They have no microprocessor, firmware
code or custom ASICs, so repairing them should be a matter of
replacing capacitors or replacing TTL or analog parts.

Wow. So jealous. The 4014 is such an awesome terminal - can't believe you've
managed to find *three* of them, much less all those others. That blue one - is that
actually a blue picture tube, or just the normal Tek storage tube with a blue filter?

Its 5 actually (3 with glare hoods, 2 without); 7 if you include the

I haven't powered that one on, but I suspect its green phosphor with
blue safety glass shield. I do like the blue anodized aluminum look
of the case, though. The blue one was sitting outside in the yard of
a surplus dealer. It will need careful inspection and possibly some
restoration work before power-on.

Yeah, the safety shield is blue (actually sort of a blue-green). I
used one of these in the 1970s and found it useful because you could
display a comparatively large amount ot text (for the time) on a
single screen. On the other hand, once the display was full--poof!--
the screen was erased and started all over again. No scrolling on
these things.

Thought #1: Wow!
Thought #2: I'm jealous
Thought #3: I sure do miss the 4014 (I guess it must have been
a 4015, because I'm pretty sure it had APL) I used in college
Thought #4: Where did you say this warehouse was?
Thought #5: If you find one of those 4015s has been "liberated,"
it wasn't me :)
Seriously, that's a very impressive Tek collection.

Its in Salt Lake City, where I'm housing the collection of the
Computer Graphics History Museum that I'm building.

The building has a security system :-)
Seriously, that's a very impressive Tek
collection.
Its for my 1970s exhibit: I want enough Tek terminals that 4-6 people
can simultaneously have a vintage hands-on experience.

Wow, lucky!
I used a 4015 for APL programming on a Burroughs B6700 for awhile ...
it took me *decades* to break the habit of clearing the screen when the
cursor got near the bottom :)
I remember when I first saw HP's HP2641 terminal ... I was disappointed it
couldn't do all the overstrikes that the Tektronix 4015 could do.
Of course, the Tek terminal *really did overstrikes*. The HP 2641 read
what was in memory before, considered what was being "overwritten", and
replaced the character in memory with the appropriate combination character ...
if it had one. Otherwise, you'd see only the second character (IIRC).
I.e., it implemented a (small) set of known overstrike characters as separately
encoded characters in ROM, and did a two-character lookup to find one when needed.
OTOH, the 2641 could scroll :)

And erase! I have a bunch of HP 264x and 262x terminals as well. I
need to start photodocumenting more of the computer graphics history
museum's collection. This will mostly happen concurrently with me
creating a catalog database with Collective Access.
