Vintage hw is even harder to find drivers, BIOSs, SDKs, schematics, manuals, and such for because there's no assurance of proper archival. This is almost always seen whenever downloads were hidden behind Flash, CGI, JS, or other dynamic / link-rotten URI or were on an ftp server which IA failed to mirror.

There must be international legal minimum standards of post-sales support and EOL archival caretaking to really reduce e-waste and allow things people paid for to endure rather than forced planned obsolescence like cloud-side or update-based bricking. The corrosive consumer mindset of "new, new, new"; fragile, undocumented, closed-source, short-life tech; and throwing away expensive things is absurd.
