I still have a Commodore C-64 in the box and Commodore VIC-20 in the box(with matching serial numbers). A whole Plastic bin full of Cassette Drives, Disk Drives and Manuals! :lol: I use WinVice 3.2 for my everyday Commodore Computing!
But please only sell it to people who take care of it! I hate to see people buying retro-hardware just to re-sell them (with margin).
Having an old machine in good hands is a good feeling. Seeing it sold again without any maintenance done to it just for the profit is making me sad.
A local retro-enthusiasts group is almost always the better choice (in my opinion)
