Hi all,
Does anyone of us know ports connection of SVI-727 80 column extension?

A think that is different for the usual 98h-9Fh for common VDP MSX1?

I will much appreciate your comments,

According to the source code of blueMSX, it's port 0x78 and 0x79. But it's not a V9938 or so...

I think that SVI-727 has an Hitachi HD6845 controler same as Motorola MC6845 used in Amstrad CPC

Does anyone know how to program it?

A lot of thanks,
