I remember seeing some prints with WD markings on it, but I was not heavily involved other than working the new distributed front-end which we did with LSI-11s. Somebody from the CMU HW lab like Jim Teter might know, although he did the 11/40e for C.mmp, I'm not sure who was the microcode guru on CM* as that was all happening as I was leaving. I sent a couple of emails to folks like Danny Klein, Mike Liebensberger, and Tron McConnell. Danny and Mike are SW folks, Tron was a EE/HW type but mostly worked on other stuff at Mellon Institute in those days. But, IIRC, Tron was worked on a 3Mbit Xerox board for the LSIs, so he might have had something. We all did some stuff with CM* (Mike more than any of us). FWIW: Tron was (is) a bit of packrat and if he ever had anything like that, he might still have it. --000000000000c1e7aa059c31fbf2 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable
