(Old thread but the only one on the subject)
Got a C64 and a C64 mk II, haven't checked in the health of those since i last used them (sometime in the 1980s).
Purchased a C128D from a coworker in the late 90's, i prepared that for storage at least. Still haven't found any CP/M disks to try it out (main reason was to try that out, the C64/C128 i have played with for a substantional amount of time).
Started out with a Kickstart 1.2 Amiga 500, then i got a A1200/HD which i sold. Then i bought a A1200/030 in the early 2000. It's still in good shape, but i cant even begin to remember where i put the powersupply for it. I tested it out a few years ago, and the video output worked perfectly on my projector, was quite cool to see the Amiga display on a wall.
Purchased a USB "floppy" drive + CF card HD replacement to go with the A1200 about 2 months ago, but i haven't gotten around to attaching those just yet. Will be a later project when my energy returns.
Have thought of doing retrobright on all older boxes, but i found out recently that there are replacement boxes you can buy which are UV resistant and does not yellow over time. Just hope they produce some more and for the C64/C128D as well, those are starting to become yellow as well (except for my black C64 that i modded with a few things in my youth).
Hoping to find a Vic 20 some day, most of the ones i see are sold the same second they are put up for sale, it's the first computer i ever had and i'd love to have one again some day.
