Unicomp M122 with PS/2 connector, $41.09 incuding US shipping

Sold as untested, but very likely to be still working.  Looks like a regular PS/2 connector, so hopefully no exotic converter needed.

Not sure why this auction seemed to have been ended by the seller, but if you look closely one of the pins on the PS/2 plug broke off, which would have been a pretty easy fix.

I don't think they broke. The 2 absent pins are the 2 that don't do anything anyway.
"Starting in 2011, the deficits again started to shrink. During Obama’s term  the deficit was reduced by $900 Billion  before finally in 2015 the GOP managed to wrangle a “reconciliation” bill out of Obama where he again cut corporate taxes, as well as made permanent some of George W. Bush’s original tax cuts. This is the year everything reversed. Before this, under Clinton, Bush and Obama the deficit in almost every year was gradually decreasing. The balance we had of taxes and the economy was bringing the deficit down, the money coming in was slowly catching up with the money going out until 2015. Trump’s subsequent tax cut has continued the new trend even after the rest of Bush’s cuts have since expired. Obama had an average GDP of 2.3%, with 11.6 million jobs created and unemployment peaking at 10% in 2009, then falling to 4.3% in 2016. If we had continued on that downward deficit track, we would have again reached balance and another surplus in 2017-2018.

Its funny I see so many more DIN 5 connectors than mini DIN 6 in my collection, I tend to forget PS/2 had frequently unused pins.
Either PS/2 had a somewhat short run as the primary keyboard connector before rubber domes became the thing, or all the PS/2 mechanical keyboards are still being used so I can't buy them cheaply.

It makes sense though, pins that aren't there can't bend or break off :p

That spare pin on the AT connector occasionally/rarely saw action as the "reset" connection but that was the exception rather than the rule.

There are millions of rubber dome PS/2 (mini-DIN6) out there but I think that mechanical switches were fading out as PS/2 was coming in.

Of course, IBM provided Model Ms with PS/2 systems from day one in the late 1990s but it took a while for inertia to wash through the industry.
