The first use of a minicomputer with a CRT display to edit documents dates to at least around 1960. It would have been technically possible to do a similar thing with a CRT display in the 1960s. They could be used to edit documents, in a way. It worked somewhat like a Flexowriter, which was a similar typewriter system but which ran off paper tape.

It was a Selectric typewriter with a magnetic tape unit. You might be interested in the IBM MT/ST, released in 1964. Many hundreds more bytes.Ī reason for asking is to possibly discover unknown machines. Read or type bytes in to point at buffer, read bytes out to tape or printer.

Just a simple sequencer, and a buffer, tied to an IO device and a CRT tube. We might try to avoid even that! No software, per se. Documents will need at least a few kilobytes of memory for buffers while edited. A classic computer-style word processor is going to be at least several kilobytes of software. It'd be fast enough, and relatively cheap and compact - it could probably fit on a single large PCB even with 1960s discrete technology.Īs foreshadowed, the problem is the memory. With the right design, A bit-serial processor in that style, would be fine for word processing. Many of those 1960s calculators are indeed basically little microcontrollers, with a sequencer as sophisticated as a general purpose CPU. In computing's early history, the main limit was not usually speed, but memory capacity. And am now thinking if Delay-line memory may have been an explanation for some very early radar consoles appearing to generate alpha-numeric characters on their screen ( not done by a transparent physical overlay on their screen ), which I have seen on tv, which seemingly appeared to be from the late 40's. NOTE - I cannot find how data on Delay-line memory was edited after input, assuming some machines allowed editing, these crt-calculators would probably not have.Ī reason for asking is to possibly discover unknown machines. Video-Games - This would probably involve more circuitry / logic, and of course very few could have afforded one for video games. ( A simple cable could have connected to printers, or simply take tapes to compatible printers ) Word-Processors - How difficult would it have been to save what was on the delay-line memory onto tape. The TI-30X IIS is also available in pink and blue.CRT-Screen-Compact-Desktop-Calculators of the 60's, could versions of this tech have been made as word-processors or even video-games? The calculator is ideal for general math, pre-algebra, algebra 1 and 2, geometry, statistics, and general science. A snap-on cover fits on the back of the device or can be slid over the front of the calculator to protect it when not in use. The calculator uses solar power and internal battery as a backup source just in case there’s not enough light. Or, use the entry line scrolling feature to review previous entries so you can look for patterns within answers or simply retrieve answers to previous calculations. Make a mistake? Use the arrow keys to scroll through the original equation to recalculate the answer. The calculator is capable of performing operations with both fractions and mixed numbers - you can enter fractions exactly as they appear in the textbook, no conversions necessary. The two-line display shows both entry and calculated results at the same time. The Texas Instruments TI-30X IIS Scientific Calculator is versatile and reasonably priced.
