Recommended Posts

Hi Mitch

Where can i get the released one????

I do not know,which one it is.

greetings Walter

 

It's the one in the 7800. The Maria 1 (model 1701) never got released, the Maria 2 is the one they used in the 7800. There were originally going to be three versions of the Maria 2, NTSC (1702), PAL (1712), and a universal that included both (1722). I don't think the universal one ever got built though. Do your chips have a model number on them?

On both chips is this

 

350 ES

VC20498

And then on one chip is the number 205 and on the other is the number 56

 

That is all,i can say.The only thing,i have is the warrynty,that both chips are protos.

greetings Walter

 

They're probably WIP versions of either the 1702 or 1712. Cool find.

Is this the one they made without the Display List Lists?

That was the 1701. 1702 is the released version, with DLL. So assuming this is a 1702 prototype (which I guess hasn't been fully determined), then it should have the DLL's.
