Radio Shack, as a job, was/is a step above fast food, and a step below clothing, in terms of status. If Comic Book Guy from The Simpsons wasn't selling comic books, he'd be a Radio Shack employee (if you were lucky). The people attracted to that job were not serious sales people, and the things they were made to sell were mostly undesirable, or worse incomprehensible without expertise. The store was filled with trash items that sold at christmas and broke by valentines day. All of this, right next to certain niche and high-end items that rarely moved.
Because Radio Shack sold a lot of cheapskate wares, everything bought from Radio Shack felt like a gamble (as the store's very name should suggest). The revolving sales associates had distractions about battery sizes mixed in with thousand dollar sales, so if there was commission to be had, they were still forced to swat flies.
Radio Shack was usually a hole in the wall. 900 square feet would probably be a large-ish Radio Shack. Without zones or departments, every Radio Shack employee was always selling everything, which means they were pulled in every direction, and their motivation landed somewhere in between selling fuzzy slippers that sing Jingle Bells in electronic chirps, and selling sub-par desktop competitors to Gateway 2000, without fully understanding or caring about the difference between an Intel 386 and an Intel 486DX.
Because Radio Shack was a high school summer job at best, or a 9 to 5 career move at worst, it's interesting that they lasted decades longer than maybe most people would have expected.
They were once a great store, staffed by smart people, and had quality goods.
Businesswise, unfortunately, the founder Radio Shack died right before the computer revolution kicked in. Then, Radio Shack had a couple of embezzlement problems right at critical points so they missed the computer revolution and then missed the internet revolution.
And even THAT would have been recoverable had they decided to be "mom and pop" tech support in less urban areas (it took forever for Circuit City and Best Buy to enter certain areas).
Did you know that there was an English clone called the Dragon 32? And that it had 64K RAM that was never advertised but that you could use by tweaking some bits in the video chip/memory controller?
Some fun I had with it last year: https://twitter.com/robhawkes/status/707270758393847809
Unfortunately I lost all my '09 stuff. Did he write in Asm or something else?
I had a rudimentary random-access storage device going on mine using a Sony TC-FX 33 cassette tape recorder. With a bit of tweaking you could control the buttons from the Dragon and it also had a nifty little optical encoder to indicate 'end of tape' that you could tie to an interrupt giving your a rough idea of where the tape was.
Even with a C120 cassette the storage capacity was terrible but it did work and it was persistent. It wore out tapes like crazy :)
That Dragon really does look mint. Beware of the big caps dying on you and taking the mb with them, it might be safer to replace them pre-emptively that power supply wasn't the best. A huge advantage the Dragon had over the original CoCo was the keyboard, it is really good quality.
We figured all this out long before the Dragon 64 was released, and a friend of mine figured out how to move the basic interpreter to RAM and relocate it. Good times.
You may want to dive in to this:
It was a wonderful set of hacks. And, since almost everything was software, you had to understand what was going on rather than just magically offload it to a chip that just handles it.
The whole idea of making a dinosaur "roar" drove me down the path of sound effects, audio synthesis, ADC/DAC conversion, Fourier analysis, etc.
And the CoCo had William Barden writing books and articles that were way ahead of anything that you could have rightfully expected.
