I have an HP-25 calculator which appears to function ok in non programmable mode however when I try to programme it every key stroke returns a 13 00 in the display. Unfortunately I know nothing about the electronic internals of the calculator but would like to get it fixed. Can anybody recommend who/where in the UK I can get it repaired.
