Re:
Media 100, an exceedingly popular tool in the video industry, is a perfect example. Desigated card
should go into 'Slot #5'. Of course, with only 4 slots, 'Slot #5' isn't easy to find. Now you have to
get additional expansion chassis...<g>

I checked into it. The G3/266 through the G3/400 B&W are tested and approved by Media 100 Incorporated. The G3/266 with the Adaptec 2940UW, and the G3/400 with the Adaptec 2940U2B. Support for the B&W G3 requires Media 100 software version 5.5.1 or later and a system software update from Apple.
Media 100 xr works well in the G3 B&W. However the 4 slot limitation precludes support for a second monitor without an expansion chassis.
Media 100 xs has a dual monitor configuration without an expansion chassis, however one must bus down the synchronous transfer rate of the SCSI controller to permit the additional bandwidth required of two monitors. Also, the Griffin gPort serial adaptor uses the internal modem port, precluding the use of an internal modem, and can only be used for machine control.
Slot 1 - ATI Graphics card
Slot 2 - P6000/Vincent
Slot 3 - Second graphics card
Slot 4 - SCSI card
Media 100 le, lx and xe all support dual monitor configurations without an expansion chassis in the same manner as above.
Media 100 qx does not support dual monitor configurations.
It is informative to note that the 80MBps speed of the LVD SCSI controllers can monopolize PCI bandwidth. By slowing down the synchronous transfer rate to 20MBps, data rates of 300 KB/frame can still be achieved with the G3s.
Clearly the limitation is one of bandwidth due to over taxing the PCI bus for both video I/O and storage traffic. Perhaps if Media 100 would embrace IEEE 1394 the quality and functionality of the user's experience with their product would be enhanced. It seems however, that the company is rather instead pressing new buyers with their NT product for the time being.
Verssen must be having a frustrating time with the Media 100 xr.
