HP 9830 notes:
  • Memory was reallocated from registers to program as needed. Because lines where highly variable in length there is no fixed maximum # of line
  • Batch BASIC option allowed the machine to accept and execute BASIC programs on marked or punched cards. Terminal ROM allowed the machine to act as a terminal. Advanced Programming II ROM added sort, search etc. for database applications
  • Only the Math pac is included above so far. No other ROMS/pacs
