The 1990s era Casio I inherited from my late father has developed a defect in the LCD screen; and a newer one I got at the local supermarket (intended for high school students) although just right for A/AS level exams lacks some useful functions for computer science (such as hex, octal and binary) and doesn’t have much programming capabilities.
I am considering treating myself to a new one; as TBH its about time I actually understood a bit more of the numbers behind what I do such as converting milliwatts/watts to dBW for radio communications; working out lag on telecoms circuits by comparing this with the speed of light etc; as well as impedance matching in electronics.
Any of the clever folk here have suggestions about which models to get? I originally thought the TI and HP programmables were unobtanium here in Europe but you can purchase them onliine (quite like the idea of those with an entire Z80 CPU built in to them 😉 )
I’ve noticed the ones that used to cost about €300 are way cheaper
