Over the years, VTech followed up the Precomputer 1000 with various upgraded models like the Precomputer 2000, Junior, and even the Power Pad laptop. But the company’s most ambitious learning computer emerged only one year after the PC 1000.
Like the PC 1000, the I.Q. Unlimited Computer shipped with a one-line LCD, but you could attach it to a much more impressive display: a color TV set. Once the I.Q. was hooked up to a TV or monitor, kids could do word processing, create spreadsheets and graphs, make databases(!), draw pictures, or play built-in educational games. The I.Q. permitted users to save their work in the unit’s battery-backed memory or on removable RAM cartridges. The I.Q. also offered BASIC programming and the ability to print documents through a standard printer port.
This ambitious machine may have pushed kids’ computers too close to the territory of “real computers”. In any event, it wasn’t as successful as the Precomputer 1000 and didn’t spawn a host of imitators. In some ways, the IQ established the upper limit of how capable a learning computer could be–a limit that manufacturers of educational computers seem to observe to this day.
