I always used a bench vise to crimp 40 pin floppy, 34 and 80 pin IDE, and 50
pin SCSI IDC connectors onto ribbon cable. Never had a problem.

*PRO TIP #1 -* A hotter iron is better for soldering pins in connectors
with low melting point plastic. It sounds counter intuitive, but the
goal is to get in and out quickly. You want to dump heat into the pin
as quickly as possible, melt the solder, and then stop heating the pin.
A lower
Beware of the cheap solder-cup connectors they are selling on amazon and
other places. They are made out of the wrong kind of plastic and even with
a temperature controlled iron and a quick hand, the pins can shift.
If a quick jab with the iron leaves a dent - throw them out.
I just threw out

While I agree, it
For all the time spent chasing cable problems it might be nice to have a
chip on a board that would echo signals and generate error messages.
Without good diagnostics one is like the puppy chasing his tail.

In that case you should probably boot the 2.8 installer in "Live" mode
to run a latency test before committing to an installation.
I did install 2.8, the installer did give me

Greetings all;
I, despite seeingthe signals on the bobs input
I don't run ribbon cable any longer the 12inches, and keep it against metal
surfaces to minimize noise induction into the cable.
There are ribbon cables that have the pairs twisted for a length, but you
are limited to connectors every foot.
I use shielded twisted paired cable for anything longer.

That doesn't necessarily mean that they are making it as far as the IDC cable.
Have you buzzed the cable through?
Ribbon cable is not exactly the best when it comes to noise and speed.
Notice that no modern interface designed in the current century uses it.
I've had good luck with those way-cheap "Aviation" connectors. You can
buy them in different diameters and number of pins. and they don't cost
much.
