No, seriously, rubber dome M2 is a piece of dog****. And has only collector value. If it was buckling spring version, that's another matter.

Is it really that much worse than random rubber domes on the street today?

Simple, resell it to a co-worker or somebody who doesn't know the difference. You might be able to wheedle $30 out of that guy to cover your costs.
Most of the modding can be done on your own once you break through the psychological barriers.

When it was made - no, it wasn't. But now it's kinda 20 years old. At least. So it's crap.

These are not bad keyboards, and users would be perfectly happy with them if not for the "other" version.

I have gotten a couple of them and unloaded them on ebay for $15-20 + shipping. Be sure to disclose what you are selling and you should be able to recoup at least the cost, but probably not the freight.

Who knows, there may be a collector who wants "every Model M" looking for a prime specimen.
What this shows is that the Republican Party knows, deep down somewhere, that even before Trump they had less than a policy agenda. All they’ve had for the past decade or so is strategy and tactics to suppress the vote, either through extreme gerrymandering or State-level laws. More often than not, as we’re seeing, through both. Without a stated party platform they are left with nothing but the insanity of The Power Grab and The Big Lie. The Party as a whole has, for some twisted logical reason, decided that America no longer needs Democracy. That in the bent and tortured reality Republicans have created for themselves America was never a Democracy, the Founders never intended for the country’s politics or social order to change, that the country’s democratic features would always only extend to wealthy White Christian property owners. They’ve also, collectively, decided that threatening major, multi-billion dollar corporations that employ tens, if not hundreds, of thousands of people worldwide will somehow, for some reason, cower in the corner when State politicians decide to take a few million in subsidies off the table. When faced with hundreds of millions, or even billions, in lost business because The People are voting with their wallet, I know where I’d position my company, and it’s not at the dinner table with Mitch McConnell and his wife.

I take it the key-caps aren't interchangeable with B.S. keyboards?

Wait. The IBM Model M2 is not a rubber dome.

The M2 is an alternate buckling spring keyboard. The keys interchange with the ergonomic Ms, and standard M key stems will click into place, but the profiles are all different.

Actually there are two versions of M2 - buckling spring variant (somewhat simplified and more low-profile than regular Model M) and rubber dome one. If I'm not mistaken, rubber dome variant somewhat different in appearance from buckling spring M2.

IBM Selectric Touch keyboard (Model M2)

1395300   buckling spring, US layout
1395706   buckling spring, UK layout
60G3507   buckling spring, labeled as M1 ("Options by IBM" unbundled)
42H0468   buckling spring, US layout, RJ-11 (can be used by making adapter)
73G4614   rubber dome
60G0817   rubber dome, with a big face plate. code name "Lion"

The terminal version is fully PS/2 compatible, and merely needs a passive adapter to map the RJ-45 pins to the appropriate PS/2 ones.

I like 'em. The rubber dome keyboards IBM made back then had great tactile feedback. Nice stiff rubber domes with a very distinct "pop" feel as the key goes down.

But I think after 20+ years any rubber transforms to crap almost automatically...

I just accidentally bought a rubber dome M2 on eBay. Since it didn't work when I received it (and was sold as-is), I decided to restore it. Turns out that the internals are pretty similar to the buckling spring version (same PCB and conductive sheet from what I can tell).

I replaced the capacitors, cleaned the traces using isopropyl alcohol, and then ended up having to put some card stock below the foam to get the traces to make contact.

Now it works pretty well - the keys feel pretty good for a membrane keyboard. Not sure whether I'm going to resell it on eBay or keep it. I already have too many keyboards, and just wanted a buckling spring M2, so might resell it.
