RME Digiface plus PCI card and connector cable (not pictured in the photos, it looks like Firewire but it uses RME proprietary format). I used to have this interface on a pc with Windows XP, it was one of my best and most reliable interfaces with incredibly low latency, and the only reason I have stopped using it is because I moved to a mac without PCI expansion slots.
I have checked the RME website and they have drivers released as recently as 2023 for this which make it work with any version of windows from XP all the way to Windows 11 (except for Win 7 which needs a different driver, apparently). Search'digiface' ONLY (not any of the other versions of Digiface) on this page for Mac and PC drivers for both old and new operating systems.
