Yeah it is really happening it seems, really looking forward to some videos of hard and software in action. Big smile

If anyone can get access to (even unfinished) designs of V9978 and R800 and improve upon them in FPGA it’s Nishi. Don’t say it’s not possible, relations with Yamaha were pretty tight and R800 was an ASCII design (surely with help of Zilog). Still we have to remain realistic and it may be something different (there are too little facts at the moment).

Hope a real MSX with keyboard not like 1 chip

In his Twitter spaghetti response Mr. Nishi confirms somewhere that it will look similar to raspberry Pi 400.
But somewhere else he stated that he is working on a notebook. Maybe he’s still not sure how the end product will look like
Or there will be multiple options Smile2

Or just a translation error..

I did not know this.
Yes, it might look like that. Why not.
I especially wish that it really exists and that it is available in 2022 with also the imagined download system. (software, old and new games).
Exciting certainly but that we do not say to ourselves at the end of 2023 "it was a wet firecracker and nothing came out". I think the times will be shorter than the MSXVR too. If for example, it is available in May 2022 (I give an example), even if we have to import it from certain countries (Japan ....) it is available and not 6 months after paying in our houses

I scanned trough his tweeds last week and it’s hard to understand what he really wants and what the actual status is because there is no clear up to date requirements or spec doc....

That sounds quite similar to the speech he held in Bussum back in when-wassit...2003? lots of plans and ideas, but nothing concrete.

Anything that's not going to be backwards compatible with MSX (and no, I don't count software emulation as compatible), should not be considered an MSX imho. Smile

So PCs are no longer PCs, Mac computers are no longer Mac, and so on...

You can't run a dos game on a modern pc without emulation (and probably there are plenty PCs that doesn't have BIOS to run even disk access in real mode). That's life, sure enough any real try of rebooting a MSX with modern features will use emulation for backwards compatibility.

The difference imho is that MSX was always designed to be a standard with compatibility in mind, including backwards compatibility.
The Intel Macs (and now M1 I guess? Haven't really been keeping up with them anymore) weren't designed to be backwards compatible as such with their PowerPC predecessors. As for PC games, I think the issue is more that MS-DOS has been left along the roadside, making it more of a software than a hardware compatibility issue.
And indeed, as LGR demonstrates with his video of running DOS on a Rizen PC, games will actually still run on modern systems without emulation. Sure, there are some compatibility issues such as colours being a bit off, and some 3D instruction sets glitching out, and you might need FreeDOS rather than MS-DOS to get some of the modern hardware such as USB drives accessible, but overall the hardware is still capable of running DOS games without emulation.

The msx3 is not an msx because the Turbo-R is not an msx standard.
There was only one manufacturer, with a non-standard extra cpu.
An 7-bit company can not design a 16-bit cpu.
Mr Nishi should terminate support for the R800.

Besides without happy new features, it does not bring fun.

It will bring a lot of new happy features..high speed 2K res VDP for example.

Does Zilog still make CPUs? And if so are they backward compatible with the Z80? Are they competitive performance wise?
Per their website that is not the case
https://www.zilog.com/
What are the goals the MSX3 is supposed to achieve to be considered a success?
Who is the target audience of the new standard? Is it existing fans like us in this forum, or is it also intended to attract a new generation of users and be a commercially successful and viable platform for developers small and big to support?

The v9978 specs by logic;
- 100% v9958 compatible
- optional HSync splitscreen sync bit
- 4 hardware splitscreens
- add v9990 16bitColor+modes
- Fixed 2K output

Memory;
256*256*3/1024=192KB (3x SCREEN 8)
2^21*3/1024=6144KB (3x SCREEN 8 HD)
But to get the 16bit modes usable 1 bit extra gives;
12288KB of vram
