It's not yet available, but coming soon:

http://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=39&No=83

This board is called a "low-cost" board, so I hope the price will be < 200$.
And it provides a 20K LE FPGA, which should be more than enough for the MSX!
What do you think about it?

For the Amstrad CPC we already have an available "One Chip Amstrad" for everyone called the "CPC TREX", which is nothing else than this board with the TobiFlex CPC core:

If the board mounts a FPGA with 20K LE and costs less than 200$ I'll be very impressed for sure!. The C1 model comes with only a 6K LE FPGA, right?. Maybe Altera will sell the old model a bit cheaper now...

Can you connect msx-cartridges to it?

Sure!, using Sunrise Game Reader!

Does the Moonsound work in that game reader?

There we can use an extensionboard for.

Is it the Moonsound an MSX cartridge?

Having enough room in the FPGA I think all the MSX hardware could be emulated...even a Moonsound.

Uh, since I can plug the Moonsound in my MSX's cartridge-slot, it's an MSX cartridge I'd say.. unless I'm wrong ofcourse and the Moonsound is a kettle of Tomato-soup. But the last time I used it, it didn't sound like soup!

Dunno about emulation of the Moonsound.. fpga/performance-wise.. perhaps someone can shed a light on this one? (snout?)

What a bullshit to think that it will fit.
Ofcourse everything can be emulated this way. Even the Moonsound ,but it doesnot sound soup.!
The idea is nice, but find yourself first a couple of fpgaprogrammer and someone that want to produce, if the idea is executable.
We can scream and shout about what MSX Association is doing except from not launching the idea versus price and what fits is simple the right thing. And if they want to listen a little -who knows- that problems can be solved.

Yes, the C1 includes only a 6K LE FPGA. This new one (D1) looks very similair to it with the exception of the 20K LE FPGA and some other small modifications like SD card reader instead of CF card reader.
This board provides two expansion ports (they look like IDE connectors). Maybe it's possible to build an adapter for MSX catridges, but I am not a hardware expert.
As I heard the MSX core (is it MSX1 or MSX2?) is available as open source. When this board will be available and not too expensive, and if noone else wants to adapt the core to this board I could try to ask TobiFlex to have a look on it.
I would like the idea a lot to have a not too expensive Mini-MSX2 with 4MB memory mapper, PS/2 mouse/keyboard connector, VGA-connector and inbuild SD card reader, which can be used for storing DSK- and ROM-images and accessed as a Sunrise IDE interface. Thanx to TobiFlex and the C1 board all these things are already reality for the Amstrad CPC.

You are right, Prodatron. As far as I know, MSX and MSX 2 core are available as open source Last MADRISX and RETRO I've tried a T-REX and it worked very well

can We take a look especially at msx2 sources?

@ping: I think they're somewhere on ESE's site. I doubt they're 100% up to date, but I remember seeing at least some V9938 code there.
