I recall when Radio Shack had schematics for every one of their items. Brands like Archer, Micronta, Tandy, Realistic etc.
Radio shack items will be around for a long time, and I have many of them. But the website is gone.
If anyone knows a URL that has all the schamatics, please post it. I may go on a downloading binge and download all the schamatics and manuals, before they are completely gone.
I used to think that webites remained on the web forever, but that is not the case. Had I known then, what I know now, I would have downloaded this stuff long ago.
