Re: 38 percent - maybe - it depends on how you count
Funny that, some of the last smart NICs I saw and handled in the late 80's were from Motorola, forget the board numbers but they were for 802.3 and 802.4 and supported the MAP/TOP variant of OSI and fitted the Sun-3 pedestal.
I think those last smart NICs had a faster CPU than Sun had used on the Sun-3 motherboard.
