Thank you for the explanation. Makes sense. I originally thought TransEra could import the binary token code, but it’s probably proprietary and besides, it was never worth adding such a feature since very few would ever need it. When most people were moving directly from HP controllers to HTBasic/Windows, they obviously had the HP equipment to save in ASCII and transfer their programs.
I had looked into a HP Workstation, but decided with the expense of getting a tested system and bench space required, it made more sense to write my own GPIB software to do what I need. It’s been fun.
