We don't get
actual specifications for
actual parts anymore, as, well, no one anymore can
actually read them! I recently had a discussion with the pimply salesguy at Radio Shack about them having forgotten what business they're in - I went for a lousy 'wall-wort', a DC transformer for a wireless headset transmitter that had a plug for one, but didn't come with one, and promised to 'eat' AA batteries at a prodigious rate (neww 55" Vizio for elderly parents, and my dad's going substantially deaf - driving us nuts with the TV volume up at stratospheric levels
- didn't want to burden anyone with knowing how to turn stuff on and off...). Anyways, was looking for one I had bought several of: switchable for various voltages, and had every plug adapter known to man - were about nine bucks last time I bought a few, and would cover anything (damned thing wanted four and a half volts...); they no longer had those, nor the entire line they were from - now, they had
one adjustable one for twenty dollars, and it came with your choice of
one adapter, but you had to know which one, offhand! Bought the damned thing anyway, and a couple microswitches that weren't exactly what I wanted, but were all they had... Couple days later, visited Scientific Surplus (and, if you have one nearby, it's a great place to spend an entire day, wandering around, looking at miscellaneous crap, and laughing at the bizarre labels), and found the original one I had always bought, for ten bucks, with all the adapters, and a pair of the exact microswitches I was looking for, for a buck a piece, instead of four or five! Took the RS stuff back, and talked with him about the fact that they can't compete selling consumer electronics against BestBuy, much less WalMart, but have decimated their stocking of actual electronic bits and pieces, leaving that market to DigiKey; however - that market has nearly vanished, as there appear to only be six people left in the country who stock up on 555's because they're just so damned handy, and know what to do with a TTL logic chip! I could just cry for the days of my KayPro Z80 - when, for six dollars and some postage, I had the
actual board schematic - and went happily to work with a soldering iron, 'piggybacking' a second chip on top of the FDD decoder chip, to double the frequency,
and the storage capacity!
