 |  Re: TED Rastertiming specs
Such a thing I saw only with C64, the VIC article from Christian Bauer (1996).
https://csdb.dk/release/?id=44685
It the past it was in discussion, that a big potion of that acticle can be easily converted to Plus/4 easily (due to big similarities in graphics modes), some other cannot (sprite). Some sections can be made just based on available C= and other documentations.
Certainly the raster timing, block diagrams, FLI stuff, border handling/tricks and special effect stuff need to be completely different. To the later ones very detailed TED knowledge is required, and high level of programming skills (maybe some trial and fail method to be used).
Some of them already well documented in the Effects programming section, like FLI, so could be 'almost" copy/paste from there:
plus4encyclopedia/500027
plus4encyclopedia/500152
On this scene I think half dozen of active people owns the detailed knowledge of exact raster timing, including the ppl who wrote those nice emulators. I think most of them prefer writing programs instead of writing documentation
