Both of the above products used an obsolete (and not reliable) method of determining if AppleTalk is installed (by checking certain ID bytes in the slot firmware). There may be a small number of other third-party applications out there that use this same method of identifying AppleTalk; if so, you'd need to set slot 7 to AppleTalk in order to use those applications. By now, you're probably wondering why we didn't put those ID bytes in slots 1 and 2 since they contain the real AppleTalk firmware. On a ROM 3, the same firmware image is used for both AppleTalk and non-AppleTalk use of the serial ports, so the ID bytes would be present even if AppleTalk was turned off. Also, the presence of the ID bytes imply the existence of a few entry points at fixed offsets in the firmware; these entry points con- flicted with entry points in the serial firmware. Note: even if you have slot 7 set to AppleTalk on a ROM 3, you cannot print to a network printer by printing to slot 7 (like you would on ROM 1) because there are a lot of 0's (BRK's) at the beginning of that slot's firmware). --- Mark Day, Apple Computer, Inc. mday@apple.com
