V9990 CPC Powergraph

A little of history...

Some time ago, a MSX user, SymbOS fan (more informations about SymbOS here), found us and proposed a challenge... Make a V9990 Powergraph version for Amstrad CPC computer line. 

But, what is the point?!?!

Both lines of computers, MSX and CPC, have some things in common, as the Z80 processor... and more expecificly, both machines have a SymbOS version. In this case, the difference, is that the MSX SymbOS run on the V9990 yamaha chip... Wow... This is the point!

Edo (the SymbOS fan), and Jörn (the SymbOS guy), supply us with all we need to make this come true! They sent to us, an Amstrad CPC computer and many peripherals that make out job possible! Thank you very much guys!

So here we are...



All MSX programs and games made for V9990 can be ported to CPC.

You can produce and sell a game for MSX and CPC!

And better of all... You will improve the power of your CPC!

The product was developed, the tests were made... now all we need to bring this "thing" to life depends on you!

Reserve your V9990 CPC Powergraph right now!

We need at least 30 units sold to start the production.

If, for some reason, we don't reach this number, all payments will be refunded.

Your turn!

  1. Amazing!

    Will final design use the genlock function to mix the native output at power on? This will give a unique video output.
