Anyone remember those old CAD mice from the 80s? With the custom mousing surface, region-sensitive reticle, and 12+ buttons on the mouse? Those things were so cool...
Do you mean a digitizer, or a mouse? The digitizers were impressive, but we later switched to a multibutton mouse for AutoCAD (circa R12 for DOS). I think it had 8 auxiliary buttons in a 4x2 grid, along with the primary left and right button. They were great for AutoCAD, as you could put a different osnap on each aux button, but the company disappeared before writing a windows driver. I still have one around here, so…
What brand was the mouse you're talking about?
