[COFF] Early Bell Laboratories CPU Datasheets

[segaloco via COFF]

Just wanted to share a couple of datasheets that may interest folks here. This evening I scanned both the MAC-8 and MAC-4 preliminary datasheets from late 1978. 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.

[https://archive.org/details/mac-4-specification-sheet](https://archive.org/details/mac-4-specification-sheet/)

These are Bell Laboratories' 1970's 8-bit and 4-bit microprocessors which preceded their work on the WE32000.

I have some hints on the typical development environment too. The BTL editions of the UNIX 5.0 and SVR2 manuals contain numerous references to MAC-8 and MAC-4 tools. I intend to preserve those pages too as part of a larger effort to illuminate the history of these two processors.

I've provided much more info here: https://forum.vcfed.org/index.php?threads/western-electric-component-databooks.1250931/#post-1464263
