Hey right on. I did hear back from Max, who again, is really the one who found this info. Good job Max at IBM.Chyros wrote: ↑21 Dec 2018, 16:02This is simply excellent. You should press him for as much material on these as he can come up with, it is invaluable!
Beamsprings have nine parts if you count the keycap, but not all of them (such as the housing and O-ring) are moving. Still, I can't think of anything else IBM made keyboard-wise that was "popular" at the time.
He told me that Siteline was an employee circulated magazine for IBM RTP/Research Triangle Park employees. I myself have found some references to it and some extant copies at some small tech museums etc but not many. Obviously it covers a lot more than keyboards and any keyboard material is sprinkled through out it's run. I have found there exists a 1985 20th year anniversary edition so it ran at least 20 years one imagines. At this time their archives of this magazine are not digitized so we can't access these magazines or search through them. From just that one small article and the obvious existence of our keyboards there is a lot of info we don't yet have.
He said we could ask IBM archives about specific dates of issues/articles and specific questions though. Is there any question anyone wants me to ask? Also, if anyone else wants to email the archives with specific limited question on their own it was pretty straight forward.
