on this halloween let's look at some cursed connectors. may i present: the DB-20
when two DE-15 connectors love each other very much and get together, soon they'll have a few extra pins
how about a DE-3?
big ol' waffle connector. this one is used to connect IBM tape units to mainframe computers.
it's a baby ISA connector!
this is a "Magic Bus" expansion connector, presumably some sort of dark magic.
here is a DE-7 connector. you can tell it's not a photoshop because it's a video clip.
and this thing? i have no idea. i've never seen anything like it.
this may look like an ordinary 27-pin circular connector, but i assure you that is a standard banana next to it, not some sort of fake plastic stunt banana.
be careful to fully specify your connector. don't just say "i want a 15 pin d sub connector" because you might get one of these.
or perhaps the DB-5 is more to your taste
this one is like if someone recreated a DE-9 connector from a verbal description, having never seen the original.
some people call this a centronics-style connector, but it is a Micro Ribbon connector with some extra coaxials...
the fabled DE-0
