I think it was the Centronics 770. It had severe
problems though,
Centronics had to pull it from the market and thats when Epson jumped
into the market

Models 101 and 306 used them (early 70's)

Ahh, the Centronics 770. When I was in high school (I graduated in
1987) the CompSci class used a very interesting system (I don't recall
who made it...*might* have been SwTPC?) that ran UniFlex. It had a
Centronics 770 connected to it. That thing was built like a tank,
severe problems or not!

Is there a generic name for that type of connector? They've always struck me
as pretty robust, and aside from the 36-pin and 50-pin (SCSI) varieties my
Osborne Executive uses a 24-pin for the printer/IEEE port, and I think I've
seen them as small as 10 pins or so...

The mini style was preceded by a larger style dating back to the late 50's.
I believe the original intent (the wedge shape) was for plug-in modules:
both genders were panel mount, one gender had a mounting that permitted it to
float around about 1/16 inch, so the two halves would self-align when the
module was plugged in.

No. now that they are the defacto standard for small parallel port
printers, every cable and/or peripheral manufacturer makes them or buys
them.

I suspect "Blue-Ribbon" may be the name of the original larger style, and
"Micro-Ribbon" is the name of the smaller style more popular now-a-days.
If that's correct, the plug-in input modules for 60's-era tube Tekky scopes
(for example) used a Blue-Ribbon connector, while the Centronics connector is a
Micro-Ribbon connector. Going fom the Amphenol web-site, 57 series appears to be
either a synonym for the Micro-Ribbon series or a subset of the Micro-Ribbon series.

It very well could be (or both).
I didn't know any more of the correct name than "Amphenol" until I joined
this list, and purists would correct newbies calling IEEE-488 connectors
and such things such as "small Centronics connectors".
Prior to joining this list, I had called them "36 pin Amphenol connectors
for parallel printers"

They've always struc=
I believe they['re called 'Micro Ribbon' connectors. The name 'Blue
Ribbon' is also used, but I think correctly refers to the larger version,
used for example on Tektronix 500 series 'scope plug-ins.

IIRC, the standard sizes are 14, 24, 36, and 50 pins. 24 pin is of course
used for HPIB?GPIB/IEEE-488, 36 pin is the Cnetornics printer conenctor,
and 50 pin has been used foe SCSI, etc. HP used a 64 pin version on some
their stuff (e;g. the expansion unit for the Integral and the CD
interface for the HP9000/200 machines), but I have never managed to find
a source of those.
