Can I just plug in an SDL PS/2 cable in an SDL AT Model M to use it via PS/2 (provided the AT Model M has a detachable cable)?

AT is a Model F, and it has a fixed AT cable. But perhaps I misunderstand.

Tried to word that mouthful easily...

I have an IBM Model M with detachable AT cable (1390131). Can it be used with PS/2 by simply swapping the detachable cable to an SDL PS/2 cable?

Yes absolutely. And you might be able to sell the black coiled cable for a premium, they are less common and some people prefer them.

But Orihalcon's SDL-to-USB cables are the best, but they are pricey.

Thanks for clarifying that up for me.

Yeah, I've seen the SDL USB cable on ebay, I don't think I can justify that price for a cable. That said, I think using PS/2 supports more key roll rollover than USB?

Ask a gamer, but I think that Model Ms have very low key rollover inherently.

2KRO regardless of the connector. They're also somewhat heavy, long-throw and tactile for a gaming switch. Much as I love the Model M, my experiences gaming on it are sub-optimal.

Good to know the rollover is the same for all connection types.

Maybe I'm not understanding key rollover correctly. How does one CTRL+ALT+DEL with 2KRO?

2KRO doesn't mean that there are no combinations of over 2 keys at the same time possible. It means 2 keys is the largest amount of keys you're GUARANTEED to be able to press. Generally the wiring is made in such a way that the modifiers don't clash with much else.

Control and Alternate are counted separately, I believe.

SDL to PS/2 cable with something this works for me: http://techkeys.us/collections/accessories/products/usb-to-ps2-serial-multimode-adapter

Or use an AT to PS/2 adaptor, and then a PS/2 to USB convertor.
"Because keyboards are accessories to PC makers, they focus on minimizing the manufacturing costs. But that’s incorrect. It’s in HHKB’s slogan, but when America’s cowboys were in the middle of a trip and their horse died, they would leave the horse there. But even if they were in the middle of a desert, they would take their saddle with them. The horse was a consumable good, but the saddle was an interface that their bodies had gotten used to. In the same vein, PCs are consumable goods, while keyboards are important interfaces." - Eiiti Wada

The original black AT cables are lovely and beautifully made btw. It's worth the £0.50 AT to PS/2 adapter if you ask me ;) .
