Of course, the MSX compatibility can be done through emulation, or by switching to an MSX mode. Like Grauw said. There are too many legacy limitations to keep the entire machine based on MSX.

Well, I'd be happy with a USB port with support for cartridge-readers and floppydrives Smile

(or nicer: Firewire...)

well, i think i can conclude that the thing MUST be extremely versatile in every aspect.

What will it look like? Will it have a build-in display? Will it be just another Gameboy with internet? How will it use wind energy? Why should it be recycleable? Will it have a harddisk? Enough memory? What about gfx? What about sound? And why put everthing in just one chip?

sjoerd - I only know the answer to your last question for sure.

The number of components highly affects the price of a computer system. Less components is a lower price. Nishi intended the original MSX computer to be single chips already Wink

I think the new msx should come with some 3D acceleration. And why not a complete Turbo R? But I think this msx part will be left unused more and more, so maybe it will be better to just emulate the msx. If it's possible to program it in hardware, it's possible to program it in software, right?

How does this programmable hardware work anyway? Can I load 'my own' hardware in the new msx? On what planet have I been when they came up with that? Smile

VHDL stands for Virtual Hardware Description Language (or something like that) and allows you to code the behavior of a chip. A FPGA chip runs on (compiled) VHDL code. This way you can change the actions of the chip (hardware) with software. Ain't it great?

My guess is the MSX will have a preset non-changeable part of the chip and a changeable FPGA part. That's where you can create your own sound chips, video chips etc.

Tsujikawa already emulates the V9938/V9958 and the PSG, SCC and OPLL in FPGA. Others have succeeded in FPGA-ing the PSG, or the PPI, or... ... ..

Also, the design for the possibly future V9959 has 3D acceleration in the form of a polygon copy command. That is, copy a rectangle from SX,SY to X1,X2,Y1,Y2.

I think an expanded V9990 (V9999? Tongue ) would be much better, but the relatively small improvements suggested for the V9959 can already make a huge difference.

Thanks, snout.

VHDL stands for Very high speed integrated circuit Hardware Description Language. Smile

I think it would be nice to have a vdp wich supports z buffering and display list or whatever they are called. That way polygons can be used like sprites on msx.

What about screen size and resolution? From what I heard of NIshi in Tilburg, the screen will be quite small. What is the minimum?

And what about keyboards, etc? I don't like touchscreen.

The minimum resolution should be 256x192 at least, ofcourse Smile And I think it should be possible to connect a monitor. I'd like to see something like 640x480 or even better on monitors.

As far as I know it won't even have a harddisk or something. Will it even be possible to use it like a 'real' computer, or is it just a pda/gameboy/mobile?
