Agreed. I love the craftsmanship. Who makes hardware that can last more than 45 years?
My current model M is going to turn 23 in April...I suspect that it will live to see 45.
The M is a nice keyboard. I'm typing on one right now. I think every programmer should own a model M. I expect to have this keyboard for the rest of my life, unless I decide to splurge on a Unicomp replacement some day.
I love my Model M but I think this is the last go for it. It already has a DIN-PS2 adapter and now manufacturers are starting to drop the PS2 port (Dell). I feel like I get less enjoyment out of it each passing day. I have to switch to a quieter keyboard at night because of the tapping noise. And with more stuff showing up on my desk, more and larger displays, I'm running out of space.
I have a PS2 to USB adapter for keyboards my keyboard (& mouse).
Sell what you need. The regular passive USB/PS2 adapters that you can get at best buy won't work.
Totally off-topic, but this reminded me Voyager-1…
