showing the improvement in productivity, measured in keystrokes per hour, and the reduction in errors due to data being validated as it was typed. The System 5000, on the other hand, was an application engine, which needed to be sold to application development departments, or even directly to user departments impatient with the turnaround time to get a solution built by IT. The
Inforex marketing and field organizations never quite figured out how to do this.
382:, which itself ran into financial hardship in 1985, and sold Inforex to Recognition Equipment in Dallas, which had a competitive product and converted Inforex's customers to that product. Inforex's headquarters were in Burlington, MA, a few towns over from DEC (Digital Equipment Corp) headquarters in Maynard, MA. They had had sales and service offices throughout the US, Canada, Europe, UK, and Japan. In 1988 Inforex's headquarters were closed.

361:, much less an application of any consequence. The 16-bit architecture made it difficult to expand the memory; by the time Inforex was able to expand to 128KB, 32-bit minicomputers had become available, able to address 8MB of memory and disks of very much higher capacity. Very few 7000's were sold, and the model quickly became obsolete.
240:. The disk drive capacity was 2.4 megabytes. The processor address bus was now 16 bits and the instruction set consisted of 8, 16, and 24 bit instructions. Core memory was increased to 24kB. Additional capabilities were added, including a communications card which allowed the system to send data using a 300/1200/2400/4800

to a mainframe computer. For most applications, tapes needed to be moved between the 5000 and a mainframe drive. While the company was trying to market their advanced 5000 product, it quickly became obsolete due to powerful new multi-user interactive systems and mainframe operating systems that now

The revolutionary ease of use of this system can best be illustrated by an anecdote. When the first system was installed at
Westinghouse, the site employee directory was loaded into a file, and a terminal was given to the company receptionist to direct phone calls and visitors appropriately. The

Unfortunately, the company never quite figured out how to market their system. Its data entry products were sold as productivity upgrades to production data entry departments, which during the 1960s had used keypunches to enter data onto punch card decks. Inforex could market the 1300 series by

systems. Repair, and correction of circuit design errors, were handled mostly by field office personnel for no more than 30 to 50 wiring changes on a single board; larger circuit design changes were handled by the factory and their programmed assembly systems.

The
Inforex Key-to-Disk-to-Tape system allowed an operator to directly read, edit, and write back any single tape record directly onto the original 9 track output tape, in the record's original position on the tape, allow keying errors to be corrected quickly.

Already a leading key-to-disk data entry system maker with the 1300 series, in the early 1970s
Inforex tried to expand by creating turnkey file management systems, in response to a request from Westinghouse, which was trying to keep track of 750,000

The original processor had four registers, one being 8-bit, used for data, and the other three being 12-bit, used for data manipulation and addresses. The commands for the processor were 8 and 16 bits long. The original disk capacity was 800

By this time, the key to disk market was also severely declining, again due to the direct entry terminal-based systems that now prevailed in the marketplace. The company became so cash strapped that they were forced into

This was an expansion of the 1301 system, released two years after the 1301 system. The biggest difference was that the system could support sixteen key stations in two banks of eight, and 12kB of memory.

The company developed one of the first distributed processing systems, the model 7000. All components of the system, except for the printers and monitors, were made by the company as third-party

Key-to-disk systems were systems that took data entered by users from keypunch-like keyboards and held the information on a hard disk. The information was then transferred from disk to 1/2-inch

At the time, large-scale entry of data for processing on a mainframe computer was labor-intensive and expensive. For example, a typical sales order might go through the following steps:

The company also made model 3300 max-edit data entry and model 5000 for high volume data base management. These used 5-platter "washing machine" style hard drives.

181:
The advantage of key-to-disk systems over card punches was the ability to see the entire content of an 80 byte card on a monitor to edit and correct mistakes.
