Yes. I know of 3 datasheets from National Semiconductor, 11719 DP83934CVUL-20/25 MHz SONIC-T Systems-Oriented Network Interface Controller with Twisted Pair Interface 10492 DP83932C-20/25/33 MHz SONIC Systems-Oriented Network Interface Controller 11722 DP83916 SONIC-16 Systems-Oriented Network Interface Controller The publication numbered 10492 is the one that Laurent linked to. It and 11722 both have the same table of contents. The references I gave in the patch descriptions are applicable to these. (Having said that, I see now that I did mess up one reference. I'll fix it.) The "1995 National Ethernet Databook" on bitsavers has more information. https://mirrorservice.org/sites/www.bitsavers.org/components/national/_dataBooks/1995_National_Ethernet_Databook.pdf -- > Thanks, > Laurent >
