Late 70s, I think, with a Radio Shack Color Computer, complete with cassette player. It took me about a month to bump my head on that, and I wound up with a Commodore 64, fitted with two floppy drives (they needed cooling towers to stay in operation, made from cardboard), a 300baud modem to connect to Compuserve, and a color monitor.

I wound up replacing that with an XT, then an AT, both Wang, and finally built my own 386 in the 80s. It's been quite a ride, and I've been low-bridged many times by the evolution of "standards", like VL bus and IDE, as have we all. I have never owned an IBM box, because I had worked on some for customers, and found them difficult due to their proprietary nature. Compaq and the Phoenix BIOS opened that up, if memory serves, and Microsoft did the rest to free us from Big Blue. Funny how you tend to become what you despise, no? LOL!
