I received this catalog in the mail in 1978.  It got filed among my piles of books, magazines, and catalogs for 20 years.  I encountered it again recently, and thought some of the other classic computer buffs might enjoy looking through it.   Besides containing pictures of a number of the personal computer systems popular at that time, it holds a certain novelty value; the fact that these could all be purchased from Tandy corporation (the parent company of Radio Shack) is hard for me to believe.   In fact, I probably wouldn't have believed it, if I hadn't seen this catalog.   I've never seen another one like it, and I'd be curious to know how many of them were printed.
