So cool: I have a pet project where I hope to use a Type 28 reperforator and had your repo starred for this. Small world.

You don't need that for a Model 28; it only needs 20mA, and you can still buy 20mA current loop interfaces. It's the 60mA machines, where the current loop directly powers the selector magnet, that need this.
