The TMS9928/9929 has a YPBPr video output, this can be converted into RGB, I link a circuitry for that I found online a while ago(cannot find the link so I leave the schematic so it can be for as a mod):

That was exactly the link I was looking for, it seems my Google-fu has gone really rusty(just found it on DucDuckGo as first result when searching TMS9929 RGB)
As the side expansion port(forgot the name) exposes the YPBPr-like signal, it may be a good idea for a side expansion mod without soldering inside the machine, making it a reversible mod(maaaaybe...)
