Im interested in Nixie clocks, but i thought a calculator could be a different project, as clocks are a bit tired for me.
Ive got a few 5870 tubes to use, so any suggestions on the best approach would be good.
I expect a 4x4 matrix or something similar would work well for the keypad with some cherry MX switches.
I am trying to find a decent calculator chip to use such as a TMS-0103.
Only problem is i think most of these chips are designed to drive a VFD or LED segment display so the signals are not compatible with a nixie driver, unless there is some way to convert the logic with a different IC, any resources would be good.
Ive seen a nixie calculator using a raspberry Pi, but i think this is an overkill for a calculator.
TIA, hopefully i can make something work
