So the uni-north on the first AGP G4 and later are OpenPIC? The B&W G3 
is Grackle/Heathrow with a CMD IDE chip for the internal HD, and I'm 
pretty sure it's the same for the PCI graphics G4.

I tried copying off my firewire burner and the data light just goes on 
and then off for like 5 seconds, then it picks up again and starts 
copying for about 10 seconds and stops again. Now it's stopped 
completely. cp is waiting on uvn_fp2 and the fwohci0 thread is waiting 
on fwohciev.

I dunno if the USB code just left the system in a weird state or what. 
After the reboot I tried to copy the file down again and it started out 
at 1MB/sec then dropped slower and slower and slower, now it's down to 
40 KB/sec and dropping. Very strange.

I have two, so I can loan you one. Want any of the Data General 88k 
material I have? Our last production AViiON and CLARiiON are about to 
be taken out of service after 12 years.
