The problem with this is that it is not a matter of NuBus being one thing. Any more than saying: If that kind of support (Network cards) were to be implemented, how far would that place OBOS from a TCP/IP stack and apps (ftp, etc). Apple engineers are always improving things. ;-) From what I understand, there were something like 6 models of motherboards for the iMac. There must have been 30 NuBus motherboards. Everyone, possibly different. Yuk. >If that kind of support (NuBus) were to be implemented, how far would >that place OBOS from a port to 68k Macs (IIsi, LCII, ...) with NuBus >and PMMUs? >
