An example of the very first electronic calculator I ever owned. I built mine myself from a kit in about 1974. By modern standards it was rubbish - only accurate to about 5 significant figures on log and trig functions - but that was better than 3SF on a slide rule, and it could add and subtract! It made physics homework much easier :-)
It had an interesting feature that has stayed with me over the years - Reverse Polish Logic, no "=" button. After this I had a sequence of Hewlett-Packard calculators, all of which used the same system (though a much better implementation of it). The line culminated in an HP-42S in 1989, which I still have; if that machine can't easily do the calculation at hand, I need a PC...
In 1984 Sinclair launched the ZX Spectrum+. A fully suitable name, because the 'Plus' was nothing more then a face lifted normal ZX Spectrum, the big bang for Sinclair that was launched two years before.

This gas station in Lincoln Heights (Los Angeles) may be the only Sinclair-branded gas station I've seen in California. I think Utah is the farthest west I remember seeing them otherwise.
