I have a serial cutter-plotter (a printer with knives) with an ADB hardware security dongle. I thought I was stuck with WallStreets, the last model with those 2 ports. Are you saying Lombards, Pismos, iBooks and up, with the proper adapters, can sense an ADB hardware key, and drive a serial printer/plotter? Maybe I was mislead. Tho, if so, I guess a bigger prob would be getting 1997 software to play nice with OSX.
