I don't remember the board numbers that came with the memory. If you have specific boards I'll try to check tonight. I seem to remember some lose J-11 chips somewhere- I'll try to find them. Thanks, Paul On Sat, May 20, 2017 at 5:40 PM, jim stephens via cctalk < cctalk@classiccmp.org> wrote: >

The early ethernet schematics are best read with the a copy of the original patent (US 4,073,220) in hand. In particular, you can match up figure 5 and the explanation in the text with the schematic from Xerox. I wrote such a document decades ago but it has vanished along with many other bits.
