Generic question to all: I've got an old HP 7221C flatbed plotter. I vaguely recall years ago someone made a small drill spindle that would work with flatbed plotters for drilling prototype PCB's, ditto for solder paste dispensers and other prototyping things. Any clues, any body? Kelly William K. Borsum, P.E. -- OEM Dataloggers and Instrumentation Systems & San Diego, California, USA
