I have equipment, but there&#39;s no substitute for experience. Therefore I&#39;m looking for loose collections of old floppy disks to practice on. I&#39;m especially interested in working with disks where the binder affixing the media to the donut is starting to fail.<br/><br/>I&#39;m in London; will pay shipping; can pick up disks around here as well. Boosts are appreciated!<br/> <img src="https://assets.oldbytes.space/assets.oldbytes.space/media_attachments/files/116/108/726/554/004/811/original/4ba9da6897da7c1c.jpg"> <br/> 2026-02-21T13:15:13Z https://yabu.me/nevent1qqs8l9e45he9nng4xdkkc0z9and9uu0m6e3na37plsz3rn07yp686xqzyz2yq9dtfasyhqtuslwyw8am3yvvwsln6hl52la82x33vjg45usrslldjqm Happy Pride #rc2014<br/> <img src="https://assets.oldbytes.space/assets.oldbytes.space/media_attachments/files/114/622/112/398/659/937/original/21df6f8c2d534ed2.jpeg"> <br/> 2025-06-03T23:59:29Z https://yabu.me/nevent1qqspc9d9292ftjwr99an4f5t2rgsy3u7m2rn33wnh3nw45g28xz2xaqzyz2yq9dtfasyhqtuslwyw8am3yvvwsln6hl52la82x33vjg45usrsfs8e27 This is pretty funny to, like, maybe three people on Earth.<br/> <img src="https://assets.oldbytes.space/assets.oldbytes.space/media_attachments/files/114/067/061/084/571/636/original/905034e4aa46e017.jpg"> <br/> 2025-02-25T23:15:59Z https://yabu.me/nevent1qqstu4wgrfvvaj6dpmdxhz924szs3m2p7xz7tedgpknjs9lu68njtkgzyz2yq9dtfasyhqtuslwyw8am3yvvwsln6hl52la82x33vjg45usrsuqzalj So I&#39;m interested in running my own SMTP server at home, which means I need port 25 I guess and an IP that gmail hasn&#39;t already block-banned.
