I have a number of adapters and converters, and I use them without really understanding what they do.
For ADB-to-USB converters for old Apples, I know that circuitry is require to actually change the signals.
As I understand it, AT-to-PS/2 adapters are usually just pass-through wiring to change plug size.
But, in simple layman's terms, do the PS/2-to-USB adapters do? I am a smart guy, but I have never tried to understand what is going on electronically inside them.
I have had near-100% success with the cheapest simplest PS/2-to-USB adapters with a variety of keyboards, but other people seem to have loads of problems unless they use the more complicated and expensive ones. What, for example, does a Blue Cube do, electrically, that a $1 Chinese Y-cable does not?
Where I want to go with this is to change some of my attached PS/2 keyboard cables to USB, and wondering how to avoid the kludge of concealing wires, plugs, adapters, and/or converters inside the case so that only a simple USB cable emerges.
Thanks for keeping it simple.
