UNIX Circuit Design System

Hi all.

In some articles I have read about a "UNIX Circuit Design System", which was written originally in some version of
Research UNIX by Sandy Fraser.

Here is a quote from the article "A Research UNIX Reader: Annotated Excerpts from the Programmer's Manual", by Douglas McIlroy:

Quote:
CDL (v7 pages 60-63)
Although most users do not encounter the UNIX Circuit Design System, it has long stood as an important application in the lab. Originated by Sandy Fraser and extended by Steve Bourne, Joe Condon, and Andrew Hume, UCDS handles circuits expressed in a common design language, cdl. It includes programs to create descriptions using interactive graphics, to lay out boards automatically, to check circuits for consistency, to guide wire-wrap machines, to specify combinational circuits and optimize them for programmed logic arrays (Chesson and Thompson). Without UCDS, significant inventions like Datakit, the 5620 Blit terminal, or the Belle chess machine would never have been built. UCDS appeared in only one manual, v7.
Even this page of a book recorded by "Google Books" describes in some extent its use.

However I could not find the source code nor the manual, even though 7th Edition UNIX nowadays is freely available. (I have searched through TUHS Archives)

Does anyone know why is is not included in V7 sources and how can I get it?


Thank you in advance.

I think (and hope) the source code file is named 'ucds.cpio.gz'

Search for that. I hope that helps.
