Had one of these back in the eighties. Some corpulent, one-celled moron, folded the cover back on itself and started the process of product failure. Have been looking for a replacement on and off since. So glad to have one again. Product is very good quality, can perform a plethora of calcs and is just a delight to use and become familiar with. Sadly, no longer made.

This is an excellent calculator for low level micro development where having hex decimal and binary at the touch of a button is super handy. Although solar powered it also has an internal battery and unfortunately mine died the solar facility kept it going with the aid of an angle poise lamp and eventually I replaced the battery but it was not easy to get to.
