TRS-80 question

Back when I was deciding on my first computer (ok, well, my first digital computer... I had one of those Radio Shack "computers" with slide switches and light-bulbs, that one programmed by connecting wires to the switches years earlier---BTW, I found the original box-top for it in the basement several months ago!), I'd narrowed my choices to three machines: a Commodore 64, Radio Shack Color Computer (CoCo) and a Texas Instruments 99A. I came very close to purchasing the CoCo, but I think it was out of stock, or somesuch. Then, I re-read an article in Popular Electronics (or was it Popular Computing by then? I'll have to check.) that went into detail about the circuitry in the C-64 and it's video and sound chips; a fascinating article (I'm guessing that many others here may have read it as well). The most fun that I had with the C64 was with a sound-synthesis program, but loading programs to, and saving them from, cassette tapes was somewhat of a pain towards the end, but fun at first. :-) ...I wonder if that tape is still readable if I can find it. Over time, and after finding it a pain to do all that PEEKing and POKEing, and tiring of BASIC, I'd wished that I'd bought the CoCo instead. That's what more computers need. Of course, I don't think that large companies really want lots of people, such as beginning electronics hobbyists and others with minimal electronics knowledge, to have an easy way to perform hardware hacking and learn more about it; the more difficult it is---or at least appears, and the more difficult it is for people to buy reasonably priced things to hack with in local retail stores, the better for them, as they can sell more mass-produced, and annoyingly engineered, rubbish---where they eliminate good features that would make a noticeable difference in the product's usefuleness just to keep costs down so they can sell the product for less, or else sell it for a ridiculously high price and have a large profit margin. Just my 2-cents worth of ranting and grumbling. :-) RDD -- Copyright (C) 2001 R. D.
