Project details

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.
