128K was more than enough back then though, just because the operating systems were text-based and lean. Those floppies, were they 5.25”? Imagine booting an operating system off a 140K drive nowadays.
Even later on, as Bill “640K DOS Limit” Gates said in interview many years ago, the 128K original Mac with a 400K floppy and no hard drive was not a problem, programmers needed more discipline.
Multiplan was the first spreadsheet I used in a work setting (but on a mini- system) and I always liked it. By that time Lotus 123 was completely dominant in the MS market, and VisiCalc (the very first spreadsheet) had fallen off the face of the Earth.
Within ten years Excel was the only thing anyone seemed to be using, and Lotus, Borland, and nearly every other former software giant had either been swallowed whole or had just gone out of biz.
“programmers needed more discipline.”
He was, and is, right. For the same reason that nature abhors a vacuum, computing resources are always consumed up to and beyond the limit by programmers.
