Are these cables standard 50 pin ribbon cables like

the cable is bad, but I don't have a replacement (the one in place is a 3 position
cable that is quite short), and no tools to crimp a new cable of this type. I do
have a few 5 position cables, but before I start trying random things, I am
hoping to understand the cable more specifically. The cable appears to be
straight through, but the connectors might "twist" connections. There could
be some ground plane factor, right?
They area ordinary ribbon cables with ordinary connectors.
Straight-through, no "twists". They don't have to be kept super-short,
but do keep them as short as possible. This is a memory bus, after all.
I don't know if there's a max length spec (DEC probably didn't envision
people putting random cables in there) but I'd try to keep the whole
thing to less than 6" or so.
