Possibly part of the "SPARC Card TV" partially described here: http://www.hyperstation.de/SBus-Framebuffer/SPARC_Card_TV/sparc_card_tv.html You seem to be missing the upper board, though. > (4) Possible Serial card with a DB9 connector, although there’s WAY too > much logic for a simple serial card.

Most likely Sun's "TRI/S" token ring interface, 501-1932. https://shrubbery.net/~heas/sun-feh-2_1/Devices/Communication/COMM_TRI_S.html > (5) A SBUS card with S-Video and what I assume to be composite.

Probably the earlier Sun VideoPix (501-1706) in that case. https://shrubbery.net/~heas/sun-feh-2_1/Devices/Graphics/GRAPH_VideoPix.html
