For the very old or computer illiterate, long ago we had a thing call pen and paper. You could even get paper with lines already printed on it. I suppose one could just write down the call sign and name then refer back to the paper when needed. I know these are archaic ideas, but I'm old and slow.
Oh by the way I am putting together a spreadsheet with all of the accessible repeaters in my area. It includes things like the owner/call sign, TX frequency and RX frequency, codes, plus other stuff I just found interesting. It's not complete yet, but if anyone in the Greater Los Angeles are is interested.
