I've been using the Wayback Machine at the Internet Archive to try and find some old Toybox DX BBS threads: 8 pages of links from the original location at ToyboxEX dot com: https://web.archive.org/web/*/toyboxex.com/* - this includes captures from late 2003 to mid 2006, and (for some reason) late 2016 to 2018. 412 pages of links from the later location at ToyboxDX dot com slash phorum: https://web.archive.org/web/*/http://toyboxdx.com/phorum/* - includes captures from early 2007 to late 2018.
Currently using this to download the pages and file attachments: https://github.com/hartator/wayback-machine-downloader
