Seeing that we get all the "will this SSD work?" and "what printer do you use?" questions all the time me thinks a complete 2020 OS9 hardware guide would be a splendid idea. It could cover what SSDs to buy, what compatible printers, what Wi-Fi stick, what external speakers for your Mac Mini etc.
Would be very cool content for the OS9 lives main page. Add in some affiliate links to the products it might even net a few dollars for the work and help with hosting costs.
It would be a base for sending "newbies" to and quickly looking up things. And the content is mostly already here on the forums, just buried in various threads.
Is that something that would interest you?
