In the mean time, more videos on it have appeared, for instance from [Wayback/Archive] Action Retro – YouTube:
- [Wayback/Archive] Easy WiFi for Vintage Macs with TheOldNet Serial WiFi Modem – YouTube (Action Retro seems to have a zip-tie fetish; I’d prefer Velcro which is actually a 1940s Swiss invention, contrary to the 1960s NASA invention many still think it is)

Of these last two videos, the first also linked to this picture of converter tables, including 9-pin D-sub RS-232 to mini-DIN-8 apple serial (which could be switched between RS-232 and RS-422 mode): [Wayback/Archive] upload_4705.png (880×1874). It is referenced only from a few places:
[Wayback/Archive] “macgui.com/upload/gallery/f_0/user_2/regular/upload_4705.png” – Google Search.
The last one also shows a specific Apple ][ product: [Wayback/Archive] a2RetroSystems Products Uthernet II
Apple II Ethernet Card – This product is based on the Wiznet W5100 chip. It has an embedded hardware IP stack. Contiki, IP65, Marinetti and ADTPro have been updated to work with the new card. Please note this card is not compatible with any modle of the Apple IIc and only works on the Apple II+ RFI motherboard or newer. Fully compatible with all models of the Apple IIe and IIgs.
In the future, I plan to write a longer post on The Old Net itself.
