Urgh, I remember those Amiga ones... bloody impossible to get hold of.
It was the video port on the A500 IIRC - if running on a TV the
modulator plugged into this and was constantly falling out, so a short
bit of cable between the two was a good idea. Cutting DB25's down to
size used to work, but was a bit bodgelike :)
In some catalogue, along with the DA26. I don't think I've seen either in
the flesh...
The DB44 *might* be what our CAMAC box uses on at least one of its
cards... I'll have to have a look (don't have any photos handy). I'm not
convinced it's any kind of standard pitch or shell size on that machine
though; it might be something totally oddball.
NCD xterms use the DA26 for their video IIRC - again they used to be
hard to come by. My machine (it's at Bletchley hence I can't check)
ended up with a short trailing lead from the system board to a standard
VGA connector as it was easier than getting hold of the darn connector
to make up a lead with.
I've seen DA26's on something else too more recently, but can't for the
life of me remember what - I have a feeling that was for something
video-related too.

Like Tony,
I've never seen a real DB37 and am inclined to doubt such a
beast exists. Other sizes do exist, but they are rather nonstandard;
for example, (some?) NeXT grayscale machines' monitor connector was a
D-shell connector with, if I recall, 19 pins - somewhere between DA and
DB size. (You could make a mechanically compatible connector by
removing pins from a DB25M or by cutting away part of one end of a
DB25F, though I don't know of anyone who's actually done either.) I
suppose you could call it a DA.KKKKKKK... connector, but that would be
I've seen the 19 pin one called a DF19, and the 23 pine one (used
somewhere on the Amiga, I believe) called a DG23. I don 't think those
are official > although the DB44 does)
!! Interesting. Where'd you see that, Tony?
