I can usually one-up most anybody when it comes to my first computer (anybody except my mom, that is…more on that later). Around 1981 or 1982, I got a Sinclair ZX81, probably for Christmas or my 11th or 12th birthday. My dad says that ‘we’ assembled it from a kit, which undoubtedly means he assembled it from a kit and I watched as long as my 11-year-old attention span allowed.
The ZX81 rocked a Zilog Z80 8-bit CPU at 3.25 MHz. For those of you who grew up in the 90’s and never saw an ‘M’ in front of the ‘Hz’, that’s three and a quarter megahertz, just about 1⁄1000 the speed of today’s PCs (if a cycle got the same amount of work done, which it certainly didn’t). The operating system was BASIC, and programming was accomplished using the pressure-sensitive membrane keyboard (sort of like the pin pad of an ATM or gas pump). The keyboard was only about six inches wide, so typing was strictly a hunt-and-peck affair; even my 11-year-old fingers wouldn’t fit on ASDF JKL;.
