Model M 1389100 (1st-gen-style 122-key terminal), $40 shipped
« on: Fri, 17 June 2016, 04:14:18 »
VINTAGE IBM Model M Buckling Spring Mechanical "Clicky" Keyboard 1389100





It's the original style with the impressive two-stage risers, DIP switches and silver logo. Looks like it'll clean up nicely. They're getting harder to find, and everyone should have one in their IBM collection. Requires a Soarer's adapter (270° DIN connector) for use with a PC.

This is the last one in this seller's lot. The auction price is $44.99 w/free shipping, but a friend in the Midwest just told me his offer of $40 was accepted for one of the others.

I didn't think that the Ms had the DIP switches, most of my F-122s don't, only the 6110688s.

"However, even though I was born in the Mesozoic, I do know what anyone who wants to reach out to young people should say: Billionaires took your money. They took your chance to buy a home. They took your chance at a good education. They stole your opportunities. Billionaires took the things you want in life. If you really want those things, you have to take them back.
That's the message. That's the whole message. Say that every day, not just to reach America's frustrated young white men, but people of every age, race, and gender.
Late-stage capitalism is a wealth-concentration engine, focused on vacuuming up every dollar and putting it in as few hands as possible. Republicans are helping that vacuum suck.
How does a tiny fraction of the population get away with this? They do it by dividing the other 99% of Americans against themselves."

Not so much.  Some of the beam spring boards had 24 or 32 dipswitches that actually impacted how the keyboard performed.

The ones on the M's and F's are just for keyboard ID, and I'm not certain they were ever used in a meaningful way.

But yes, they're DIP switches, and another thing that makes 1st-gen 122s unique.

This one was the first I'd seen with red ones, too; they're usually white:

They're white here too, the dipswitch casing is red.

Er, that's what I meant. (You guys are into precision!)
