Termination rules are the same, regardless of the number of busses you have: both ends of each bus must be terminated. > 2) I added a CDROM drive. Do Apple CDROMs act as terminators?

Termination power doesn't terminate the bus. If I recall correctly, it provides power for an active terminator. In general, only one device on each bus should provide termination power, but it doesn't matter which device. Some devices may have a termination switch, but most older drives will have resistor packets. Byron. -- Vintage Macs is sponsored by <http://lowendmac.com/> and...
