I just received two Apple Mac II EtherTalk cards (part # M0405), and
connected two machines just to quick test the speed improvement. Surprisingly,
doing a finder copy of a 1.2 meg file via TOPS, we get an overall data
transfer rate of only 23K bytes per second! Times 8, that's only 184 kilobaud!
Are these boards running at 1 megabit, or ten? And even so, that's a tremen-
dous bandwith loss for protocols! (I'm used to a 50% loss for, say, xmodem
over async).  Finder 6.1a2, TOPS 2.0, EtherTalk v1.1, thin cable, straight
line between the machines, with terminators.
