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.
“At the age of 35, after 6 years as a renunciant, he sat under a tree in Bodhgaya in North India and vowed not to get up until he had found the secret of our everlasting wandering from rebirth to rebirth. Sensing trouble, Mara, the demon of sense pleasures, sent a series of distractions his way, but the Buddha-to-be would not be stirred by such trivialities.
After 49 days, awakening came upon him. In one of the great moments in world history, he saw that all things are impermanent and ever changing. He saw how we suffer because we wish the world were otherwise. And through these insights he saw his suffering itself wander away. From that point forward he was the Buddha, which, like the term “Christ” is a title rather than a proper name.
For the next 45 years, the Buddha wandered the Indian subcontinent, turning the wheel of dharma and gathering monks and nuns into a crew of wandering beggars. Together they bore witness to what has been described as “History’s Most Dangerous Idea” – that  human beings can solve human problems on our own, without recourse to God or divine revelation.”

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.
