This is the complete Disassembly of the NewBrain Rom's from memory address's A000 - FFFF.
If you want to connect the NewBrain Monitor Output to TV SCART connector use an RCA to SCART adapter, see attached. Use the Yellow input on the adapter for the Video. Alternatively build a SCART Video lead by connecting the NB Video to Pin 20  and the Video common to Pin 17 on the SCART. Note there is no Audio output from the NewBrain. I have my NewBrain hooked up to a flat screen TV which I use for all my Retro Computers including my Amstrad CPC 6128 which has RBG Colour using another type of SCART lead.
