It was the sparc flavor... but they had an Alpha too.
> According to Allen Baum, the StrongARM traces its history to attempts to make a low-power version of the DEC Alpha, which DEC's engineers quickly concluded was not possible. They then became interested in designs dedicated to low-power applications which led them to the ARM family. One of the only major users of the ARM for performance-related products at that time was Apple, whose Newton device was based on the ARM platform. DEC approached Apple wondering if they might be interested in a high-performance ARM, to which the Apple engineers replied "Phhht, yeah. You can't do it, but, yeah, if you could we'd use it." -https://en.wikipedia.org/wiki/StrongARM
And while the IP didn't directly influence Apple Silicon, the experience did:
> P. A. Semi (originally Palo Alto Semiconductor[1]) was an American fabless semiconductor company founded in Santa Clara, California in 2003 by Daniel W. Dobberpuhl,[2][3] who was previously the lead designer for the DEC Alpha 21064 and StrongARM processors. The company employed a 150-person engineering team which included people who had previously worked on processors like Itanium, Opteron and UltraSPARC. Apple Inc acquired P.A. Semi for $278 million in April 2008. - https://en.wikipedia.org/wiki/P.A._Semi
And then there is the DEC PDP, which enabled some of the former Multics developers (Ken Thompson & co) to take what they had learned building Multics and apply it to the affordable PDP hardware to build Unix, which then inspired Linux.
DEC may no longer exist, but their shadow reaches a long way into the future.
