Page 13: General Description
Flatpanel Adapter 40-pin The BAB-430 is graphic module for the BAB-40/60 CPU boards. It features the connection of video monitors and flatpanel displays. The BAB-431/433/434 flatpanel display adapter has to be mounted on top of the BAB-430. The display adapter enables the flatpanel mode simultaneous to the video mode.
Page 14: Technical Details
BGB offers a memory bandwidth of about 9 MB per second. To improve graphic performance the BitBLT engine of the 65548 can be used. Since the 65548 has direct access to the DRAM the BAB-430 offers then a better overall performance than the BAB-410 graphic module.
Page 15: Dac For Contrast Control
BAB-430/431/433/434 1 Specification 1.3.4 DAC for The BAB-430 offers a 8-bit DAC that is intended for contrast control of Contrast dualscan displays. By writing $00 to $FF into the DAC the output voltage Control changes linear from 0 V to about 3.2 V. The DAC is write-only.

Page 57: Adaption Of The Bab-430/433/434 To New Displays
For initialization of a particular display RMon uses a table that is located at offset $1A00 + (n-1)*$50 in the RMon firmware EPROM. Where n is the position of S201 on the BAB-430. This table contains the numbers and values for all extension registers of the 65548 that are different from CRT setup.
Page 58 12. Modify the table at the desired offset ($1E60 is recommended for user-defined displays, which belongs to position 15 of S201 on the Bab-430) with the values you found in steps 4 to 10. 13. Program new EPROM and mount it on the BAB-40/60.
