Still got a good chunk of Motorola databooks, amongst others, that I got from a local supplier, as they got new ones, and I got the old ones free. Same for National databooks, and they came in useful over the years, having obscure semiconductors in them that were obsolete, and nothing known these days about them. Then the poorly printed transistor, diode and IC shortform data books that held shortform info about 15000 transistors, so you could look up what that part that failed was, and what was a substitute that likely would work in place of it, that you could get locally.
When you sent off for a catalogue from the UK, and would actually get it, then go get that international bank draft to post to them, then the 3 month wait for the delivery. Yes I ordered from Maplin UK, to South Africa, and still havce the chime clock I bought as movement and chime IC from them, still working 30 years later on. Did however this week upgrade the power supply for the chime, it eats AA batteries, so in went a 10Ah lithium pouch cell from a power bank with junk connections that never worked, along with a battery management board, and the lowest power 3V3 regulator I could find. Should only need charging next year, a much better proposition than AA cells that last 3 months. Clock itself goes 2 years on a single AA cell, no worry there, and making a battery eliminator for it is a pain, as you need to get a very precise 1V3-1V4 to get timekeeping into the sweet spot for accuracy long term.
