greetings-

   i have ported netbsd/sparc from the sun4c architecture to
the sun4 (sun-4/300) processor architecture.   i've got it running
diskless on a sun-4/330 and a sun-4/370 with serial line consoles.
[i've ported the cgsix driver, but it doesn't work totally right
under X (it doesn't get a cursor)... it works ok in console mode 
with a type 4 keyboard.  i don't have a bwtwo to play with...]    
I have not done any VME support (no docs on it... need info on the 
xd disk controller).   SCSI disk stuff works on some boards but 
not others (it may be a ESP100 vs ESP100A thing?  i suspect
some minor tuning will fix this).   i have not tried booting
off the SCSI disk yet (haven't had time and am going out of town for
a month).

   is anyone out there interested in trying this out?   drop 
me a line!  i would like to see sun4 support get added to the 
main distribution (who should I contact for this?).

cheers,
chuck

ps- here is some output to whet your appetite!
