thats cool, ive found some; let me know if these work, im planning on spinning up my own to do some data-sniffing around a system 32/34/36/38 i have occasional access to.
here are my notes for the 5250 anyway:
connector for panel mount connector Amphenol 082-5590-RFX
cable ends use Amphenol 082-5589-RFX
use Belden 9207 or equivalent
the cable ends and connectors should be 50-ohm (93ohm are hens teeth) and the cable is 100ohm (also a hens tooth, but Ive seen 100, 107, 93, 78, etc.. for twin-ax characteristic impedance ratings, so YMMV apparently)
IBM 5251 terminal USB conversion (but not what you think)

Connectors look fine. Cable in theory is 110Ω but yes, for short cables it shoudn't be that important. For some time was operating with a random twisted pair cable and terminators on a prototype board and worked just the same. Obviously if you run long cables with multiple stuff connected that becomes important.

This is so amazing. I was just looking for a nice terminal project for my computer and came across some IBM terminals that looked really nice, but I didn't know how to connect them to a modern computer. Fortunately Google brought me here, so it looks like I might have a new project on my hands.

Hi, I just want to report that the 5250 adapter I got from Inmbolmie in July still works very well. The IBM 3477 Terminal I obtained works fine with the box and I use the terminal frequently - the picture quality is far more friendly (crisp) for the eyes than the normal computer screen.(In my opinion) Back in mid-2020 inmbolmie was very helpful in creating a "mapping" table for the German keyboard-layout and the money I spent was a good investment - thanks again !
