Hi!
I recovered the files from my SCSI drive and there were some files that used the basic for V9990.

Unfortunately my memory is not good enough to recall how to load them. I've been looking in the documentation that I have with the graphics9000 but it tells the specifications of the card and the new basic commands. I've also been browsing and I've found the same kind of information.

I know that there are two different basics, the one with the new set of commands and its kun version. But I don't know which files are and if they need special address in the bload command.

Any help will be welcomed.

I've followed the link and there is the information about the gfx9000. In that link, the basic I'm looking for is named PowerBasic and I can find the information about the commands and the specifications of gfx9000.

But I was looking for the binary to be loaded. In the directory where my files are I can see candidates like: V9SUB, VDXBAS2.COM, V9XBAS3.COM and V9XBAS4.BIN. I've tried them without success. This is why I was looking for the right binary to be loaded.
