the problem is not the devices but support for USB (PC/Mac) Older (Operating) systems do not support USB. I tried it out on a non usb Acer (486) laptop also just for kicks. Using serial port to USB hub system no go with windows 95 even after upgrade to win 95 with USB support. But going to Win 98 it would work. As for mac PPC only....... It will not work with a 68k machine since the systems do not support USB. And frankly the end cost would be more that its worth. Running 8.5 or higher on a 2300 is slow already. Mad Dog can try it out in his Lab sometime. Brandy jessicat at jmug.org wrote: > I think we're talking about using USB devices on an ADB only > computer. You are seriously doing this? > Andrew >
