The 1970's was the begining of a new technology change with the advent of commercially availalbe semiconductor devices.  Milt Zeutschel, Grant Record and Gordy Nicols founded Data I/O in 1972 and developed the worlds first prgrammer, Data I/O's Model 1.  Engineers used Data I/O's early programmers to design and program their products.   During the 1970's Data I/O expanded on the Model 1 developing  the worlds first:

  • GANG/SET Programmer (Model IV)
  • First Processor Based Programmer (System 19)
  • First GANG Programming Module (GangPAK)



The Evolution of the Model 1 Programmer


Model 1:  1972 - 1975 - First Universal Device Programmer

  • Designed to program the first three PROMs
  • Integral paper-tape reader/perforator and binary keyboard
  • Optional personality cards and read-only cards contained the programming electronics for each different PROM available



Model V & Exatron 800B:  1975 - 1981 - First Programmer to Blank Check, Program & Verify in one Operation

  • Established Data I/O as the world leader for programming.  Versatile and easy-to-operate, it used the same personality card sets as the Model 1 to program all available PROMs to semiconductcor manufacturers' specifications
  • Available in binary, hexadecimal or octal keyboard configurations and featured internal RAM and a paper tape reader


 Model VI:  1976-1978 - First Gang/Set PROM Programmer

  • Model VI was the first Gang/Set programmer and programmed 1 to 8 devices simultaneously




Model IX:  1976-1980

  • Portable universal programmer with full editing capabilities using a hexadecimal keyboard and display
  • First remote control option, with process and error controls, error code displays, translation formats, a Ram-Pak interface, using either serial or parallel I/O in many data formats



Model 16:  1976-1981 - First Programmer with Load-from-Master and Serial Downloads

  • Programmed field programmable logic array (FPLA) devices, using interchangeable plug-in card sets
  • 5 inch CRT display and paper tape reader, as well as logical and array verification






Programmer Satellite:  1976 - 1981 - First Programmer Linkage

  • The Programmer Satellite allowed a user to program more than one type of device without changing card sets
  • One Satellite held up to five personality cards
  • Up to three Satellites could be connected together with one Model V to allow up to 15 switch-selectable device algorithms to be available in a single system





Card Sets:  1971 - 1981 - One Card-Set per Device Type

Data I/O card set consisted of two cards:

  • Digital card in the back to generate the precise algorithms
  • Analog card in the front generates the precision currents and voltages required to program the specific device





System 19:  1978 - 1983 - First Microprocessor Based (Motorola 6800) Programming System

  • System 19 utilized Programming PAKS to program all commercially available PROMs and logic devices at the time.  These PAKS provided the exact voltage, current and timing specified by the semiconductor manufacturer
  • Data loaded into RAM through a master device, development system, computer terminal or optional paper tape reader
  • Built-in hexadecimal keyboard for data editing and manipulation needed by the engineering environment



Gang Programming Module / GangPAK:  1979 - 1983 - First Universal Gang Module

  • Program eight EPROMs simultaneously.  The Gang Module housed the programming electronics and accepted device-specific Characterizers
  • One Module could program different NMOS devices by simply changing device specific Characterizers
