Color me impressed. :^>
Wish that'd been around in '96 or so when I replaced the LC040 in
my Performa 636 so that I could get a useful OS working on it.
(Though more because I had to wait for the part... it couldn't have
set me back more than $30.)
How's the performance relative to an 030 using NetBSD's fpu
emulation? (My guess would be pretty good, provided gcc can optimize
m68k decently these days; I can dig out an LC III to do some
benchmarking on the 030 side, if no one else has one handy.)
Is there a reliable way we can detect an LC040? Do we really just
want to do this instead of bothering to emulate fpu all the time for
mac68k in an fpu's absence, or are there negative consequences (say,
for math applications)?
