Display Board interface Flash/ SDRAM The display board interface is on the 16 way FFC flexi IC203 is a 64Mbit (32 bit x 2Meg) SDRAM. It runs at foil connector at location CON202. Power for the 135MHz display also travels on the connector. There are 4 – wires to interface with the VFD driver chip these are IC205 is a 16Mbit (16 bit x 1Meg) intel type flash IC for seen as. program storage (Player software). o XFPDIN - Data to the display board The flash interfaces to the Vaddis V

Comms and Final video output stage The signals from the main board travel up to the Comms board on connector CON902. The Video signals simply travel via an A-C coupling net before exiting the player via the RCA-phono SKT902 SKT903 sockets at locations and . The RS232 interface is on 9 way “D” type CON900, with IC900 providing the level translation and static protection between the RS232 levels and the 3.3V CON900 CMOS levels required by the VADDIS V, also supplies a +5V Status
