As Tecnobytes announced they're almost finished I'm not sure if our suggestions are still very useful. Let's see what they came up with. So far the VDP side looks impressive -- and just what MSX needed. Finally an implementation of V9990/V9958 the way it was meant to be, right? Smile

I hope Tecnobytes consider the possibility of a 3rd vdp (can be v9938 if it is cheaper than v9958) in his new MSX (in paralell with the other 2, of course). It would allow even for those that don't want to use the v9990 to make things that aren't possible on a regular MSX. Of course, if it does not make the project much more complicated or too expensive. Just my 2 cents.

If you don't use the V9990, you won't notice, right? So, it's fully compatible with normal MSX2+ and thus MSX2 and MSX1. No need for a 3rd VDP at all.

You basically get a built in Video9000 (superimpose part), I guess. Is it compatible with the Video9000 hardware? (So can Video9000 software run on it, at least for setting up the superimpose?)

snout: well, it's the best you're gonna get on how it was intended, as we don't have a real V9978...

The V9978 should have replaced the V9958 without losing retro-compatibility with some official MSX1 screens in the same way that V9958 is retro-compatible with all official MSX1/2 screens and V9938 is retro-compatible with all official MSX1 screens (the non-documented MSX1 screens are here forgotten).

True, but the V9978 was never released and the V9990 was. By including a V9958 there is no issue regarding backwards compatibility. I think it's safe to assume that this is as close as it gets to the 'original' MSX3 -- especially when you add in an R800 compatible processor. To me, it breathes MSX spirit all over.

By the way, Yamaha called both the V9978 and the V9990 E-VDP III, so IMHO they really are just one and the same.

The v9990 even contains z80 example code. Hardest thing is getting a new msx turbo r compatible I guess .

Manuel: The question is, some people don't like the V9990, and to them in respect to the vdp, it is not an upgrade to the msx they already have. With 2 vdps (v9958 and v9938) they can use what they already know to make new apps/games that aren't possible with the MSX they already have. And they can, of course, use the 3 vdp's together. Smile

Snout: I would say Tecnobytes MSX is better than the 'original' MSX3, because you can combine the power of v9958 and v9990. Smile

In my opinion even a double V9958 would be great. Do you remember the Goblin project? (also called Twin VDP System). I don't know if manage two VDP would represent a lot of work for a normal Z80 but for sure it was a very good idea and 100% MSX compatible.
