I've personally only owned Amigas and DOS/Windows machines, but my first exposure to home computers were when my father got a Spectravideo 328 plus the big box expansion with two disk drives and extra RAM. I had the biggest computers of all my friends... Then my father got a Yamaha MSX with MIDI keyboard. Quite useless FM synth, but cool nonetheless back in the day. He also got a Spectravideo 728 (basically an MSX compatible 328) and later a Spectravideo X'Press 16. The X'Press 16 was a regular IBM compatible PC, but also MSX2 compatible, IIRC. It definitely had the best looking design of all IBM compatibles at the time, but that's about it...
The 328, 728 and the Yamaha are still back at my parents', but my mother is pressing to get all of that "junk" thrown away. I don't want to see all that history going into oblivion, so I'm gonna sell it on eBay with starting bid 1 SEK. I hope someone will find it interesting.
