Does this module really exist ? It was programmed by Ken Emery and announced by Synthetix for a price of nearly $200. Two variations exist, for HP Think Jet and HP Laser Jet printers. The module was programmed in mcode and creates HP-41 barcode plots in short time. Does everyone have mor details about this, or own it ? Would be a rom-file availlable ?
