Hi all, On my road trip earlier this year one of the docs I snagged was a ring binder of Foxboro Integrated Circuits dated 10/73, Revision A, one of 200 copies. It covers chip characteristics and compatibility cross references. This was part of the doc set for the Foxboro FOX 2/10 (PDP-11/15) about which more is to come.
Anyway from this I've just scanned and pdf'd the pages for the DEC 8881, which Foxboro called the C3313AB. The first page is the relevant cross-reference to other manufacturers. I'm sure this is already on bitsavers somewhere (what isn't :) but hey what the heck, the more the merrier. The only other DEC-specific IC that is covered is the 380A. It's at http://web.aanet.com.au/~malikoff/pdp11/DEC_8881_transceiver_IC_Foxboro_pn_C3313AB.pdf Steve.
