Somewhere deep in a cellar I still have my C64 - still working, I think. Don't know whether the Datasette is still there, but I'm reasonably sure, as far as the 1541 is concerned. At least it was when I laid it to rest in favour of an Atari ST some 20
years ago.
I also still have the said ST - to be precise, a Mega ST 4 - complete with its monochrome monitor and the Megafile 30 (and of course the "blitter"). Oh my god, that was a lot of disk space at the time. Never filled it. (Actually I find it a little disturbing that for every new computer the RAM is roughly as big as the harddisk of its predecessor was...) Anyway, what I loved most about the 4 MB of memory in the ST was that some games would come up with a message at start-up, saying something like "Wow! I found lots of extra memory." and used better graphics or whatever.
I think the whole thing should still be working.
Next came the first Mac (and first laptop as well), a Powerbook 150. Neat little thing, and comparably cheap. Had its drawbacks as well, though, one of them being the four-greyscales-monitor. And due to some bug ClarisWorks could not display one of the two intermittent shades of grey.
But that didn't matter much, as the computer was mainly a working horse for my wife. She was writing her PhD-thesis at the time. And
Textures was an awesome tool for that, and ran beautifully on the machine. Its end came when one day the harddisk broke.
Which actually disqualifies it as an entry in this thread.
Then came the iBook. It was new, it was hot, it was
translucent (not just simply transparent!). I had to have one. When it was five years old I gave it an overhauling: maxxed out RAM (288 MB), bigger HD (necessities for the following), Panther. Quite a step from OS 8.6. But, big drawback:
Oolite wouldn't run on it. And, to be honest: Weren't we all tired of translucent at
some point? (Also the hull got some cracks with the time.) But apart from that, it is still working perfectly fine.
So much for my past loves (as far as computers are concerned).
