6809 based DCOM card
This was a comms card I developed for the TAB which fits into an ISA
slot of a PC. The board takes up two addresses in the PC's IO address
space and handles all of the link level aspects of the comms between
the PC and the host system (Jetbet). This board is used in the video
controller at each race track to get the raceday information into the
local teletext system. The DCOM card is also covered in the software section.
