IBM Model M AT vs PS2 Cables
« on: Sat, 15 January 2022, 09:49:31 »
Ok keyboard nerds, I could not find this answer with a simple google search so I hope yall can help clarify this for me. So the model M was released during the end of the Personal Computer AT and the beginning of the Personal System 2. Meaning that model Ms can either come with a black cable that has a 5-pin din for AT or a concrete PS2 cable.

So what I'm curious about is can I take a normal model M with a PS2 cable and swap it with a black AT cables that came on the early model Ms?

If not, what inside the keyboard makes these two generations of model Ms use different sets? Could this be accomplished with swapping a single chip on the inside of the keyboard?

Here's some proof of detachable black cables in case y'all are confused.

My experience is that both of the cables can be be plugged into the SDL socket and work properly.
“In future cases we should reconsider all of this Court’s substantive due process precedents, including Griswold, Lawrence, and Obergefell.”
** by Supreme Court Justice Clarence Thomas 2022-06-24 **
- Griswold v. Connecticut is a 1965 decision that married couples have a right to privacy, including on decisions about contraception, and that a Connecticut law banning contraceptive access even for married couples was thus unconstitutional.
- Lawrence v. Texas was a 2003 decision striking down a Texas law banning sexual acts between people of the same sex.
- Obergefell v. Hodges was the 2015 decision legalizing same-sex marriage.
What all of these decisions have in common beyond that they gave people rights that Thomas does not want them to have is that the court’s decisions invoked “substantive due process,” a legal argument Thomas thinks is in itself illegitimate.

update: bought model M black industrial cable.
It works perfectly with the orihalcon converter that I use to drive my Model FAT!
