[TUHS] [COFF] Early Bell Laboratories CPU Datasheets

[segaloco via TUHS]

And now I've started a repository here: https://gitlab.com/segaloco/pwb5btl_man

This will slowly accumulate reconstructions of the various manpages in the BTL edition of the Release 5.0 User's and Administrator's Manuals. I've started with the MAC-4 development utilities, and intend to tackle the pages for the MAC-8 and BASIC-16 environments next. I'll be adding various pages from these manuals over time, in the same spirit as my 4.1 3B20S project. I look forward to the opportunity to share these materials around Bell Labs's use of UNIX in their hardware design operations. Will probably start a more focused TUHS thread when the repository has more stuff in it, but a Bcc mention for now.

While many details of the MAC-8 are currently known, the MAC-4 has been elusive in my study until I received these documents in a collection of MAC-8 materials.
