Casio is bringing back its iconic 1980s Gaming Calculator later this month

While there’s more technology at our fingertips than ever before, it’s still possible to find joy in the games of yesteryear. Take the success of Nintendo’s retro SNES/NES console for example. The last two holiday seasons have been overtaken by unending demand for these remakes that are still largely sold out at retailers in North America. Casio is looking to cash in on this throwback trend with the reintroduction of its Game Calculator SL-880.

Made popular in the 1980s as one of the first calculators to introduce ‘apps’, the SL-880 delivers simplified games such as a Space Invaders-inspired numerical shooter. Just how in-demand is an original version? There are eBay listings currently fetching over $200 and you can expect the revived version to be a hit as well.

Originally released at the Casio MG-880 some 38 years ago, this calculator set off a decade of reinvention for a product category that was largely stagnant. As technology progressed, it was possible by the late 1990s to add a variety of games to popular alternatives from Texas Instruments and the like. I for one always loved a game of Worm or Asteroids during algebra class.

Casio saw so much success with the original model that it subsequently introduced several additional models of this calculator. As years went on and competitors like Texas Instruments developed more high-powered devices with greater features, Casio’s 1980 release faded into the background.

Flash forward to today and Casio is set to unleash a refreshed version. While it looks similar in design, you can tell that more modern-day materials are being used here. Of course, at its core, this is still a calculator. But we’d venture to guess that most will be after this release for the invaders game.

Like the previous iteration, this simple game is handled with the plus key serving as the beam canon trigger. There are three turrets all together that must be knocked out in order to advance to the next round. Obviously the graphics here aren’t mind-blowing, but there is something rather endearing about playing a simple numbers-based game.

At this time, release details are still somewhat murky. We know that Casio will put the new SL-880 model up for sale in Japan on March 23rd with a price of around JPY 2,000. That equates to $19 here stateside, whether or not it comes to the United States. Given the amount of interest we’re seeing on eBay for the originals, it wouldn’t surprise us to see releases hit the secondary market.


Game calculator revived in the 1980s

Casio Computer will release the ” Game Calculator SL – 880 ” integrated with a calculator function with excellent practicality and a shooter that will hit the enemy invaders with a beam gun on March 23.
