I'd say it's a variation on the AT&T 510 personal terminal. Same design, layout, and connector just different keycaps... https://www.classicrotaryphones.com/forum/index.php?action=dlattach;attach=3... W.

They are trying to figure ou t what computer this thing is actually designed for, and could use some help. With the amount of former AT&Ters on this mailing list, I figured this would be as good a place as any to start. The keyboard can be viewed by its' original ebay listing: https://u9396777.ct.sendgrid.net/ls/click?upn=u001.nLjt1y3hHfeY9eAAc7UsmuprK... You can see that it uses an 8-pin shielded data link (SDL) cable to connect the keyboard to the computer. This is _different_ from the 6-pin SDL that IB M used to connect the PS/2 mini-DIN cable to the original Model M keyboard. While it isn't branded, its clearly using the AT&T/Olivetti design language, which makes sense given that its coming from a former Bell Labs person. Any thoughts?
