Thanks for the suggestion, will take a look at archive.org and will make sure I add them on this forum also.
@rockdoc2010 : already sold the Atari 820 a few weeks ago. Believe it or not, but even though it hadn't print for 25+ years, I sent a few lprint and it print right away. The ink was still a bit pale, but still readable.
@slx: Thanks. 10502PC looks awesome. I have some items up here https://www.ebay.ca/sch/attic_fresh/m.html?_nkw=&_armrs=1&_ipg=&_from= . You can save my as a seller to be notify on my new ads (already sold some interesting items, but I have still have a lot). I will probably take a break of eBay for a few month with Covid-19 to avoid going out to the Post Office (things are moving fast here in Québec), but it will only give me more time to archive properly the interesting stuff and prepare more ebay ads once things becomes a bit more normal again. And I agree, a baby is even nicer .
@Sugarland: Actually, it's one of the reason I hold on to a lot of stuff, as a fan of history, computers, video games, I want all of this to be preserved for the future. Took me quite a while to decide on selling them. I was hoping to find a computer museum in the Montreal area where I could donate, this way I could go and visit it, but there is no such thing in the area. Anyway, better in someone else collection than in my closet :).
