Again a calculator with extraordinary design. With the 86 series, Omron produced in the sevienties calculators, which distinguished with their roundings from other calculators, which used to be angular.

In and on the Omron 86R, everything is round. The case has got rounded edges, the AA cells are round, too, as well as the keys, even the VFT tube is an old round model, containing 8 digies. These kind of VFT tubes has been replaced very soon by flat and angular VFT displays. Finally, the LED, which display negative values and overflow (= values > 10^8), are round, too.
The usage of two different kinds of displays (VFT and LED) were only used in a few calculators for a very short time.
All this makes this calculator so loveable.

Another interesting thing, is to see the effors of this calculator, while he is calculating. Since the display isn't switched to black, it permanently shows the current provisional results
Compared with other calculators, the Omron is a rather slow one.

Due to its lovable vintage inner works and its very modern design (in the seventies, of course), this calculator is a very interesting piece of my collection.

The Omron 88R is, concerning its design, probably one of the most spectacular calculating devices of the seventies. It's not that uncommon, since Omron made quite a couple of futuristic shaped calculators at that time.
Its softly swung case, which gets larger on the top, lies perfectly in your hands; you can operate it without having to put it onto a desk. This is also supported by the fact, that the keys work precisely without unwanted repititions - a thing which wasn't common these days, even not at Omron, too.
The 88R fascinates by its inner workings, too. The main circuit board is connected by two contact rows with the keyboard and battery board. No wired are needed, and the thing is very much service-friendly. You don't find this too often; I believe, the costs for that kind of construction were simply too high.

The calculating functions of this calculator are very common, nothing spectaculary. The display (round VF tube) was common at that time, too.
I got this calculator for approx US$ 2.50 at a local flea market, in perfect condition and together with its original manual and leather case. It certainly was one of my very best finds ever.
