More to the point, who is SIMON GARSTIN, and what makes him think that it is OK to post MY schematic file, with no accreditation on that page!

The internet is a great place for sharing ideas and getting help, I am only to happy to share my (probably suspect) designs with others - but surely, some credit is not too much to ask? Wanton plagiarism really pi**es me off!

The schematic is a development version (0.9), send to someone privately "for info" while I worked on the detail. I have now completed the schematic, and the next step is to build it -so far, this schematic has NOT been tested, or even built.

anybody tried to overclock the 9958?

With an faster RAM, better cooling system, and using a monitor capable of higher frame-rate.

anybody tried a setting x2?

imagine the velocity of the co-vdp commands!.

Hi,

Version 1.0 of my schematic can be downloaded from here :-

V9958 Video Schematic

NB: I am pretty confident that this design will work, it is based on the Panasonic Turbo R design, but at this point it has not been tested. I am just about to build it and will report back in due course.

In the meantime, I would welcome any comments, criticisms, or suggestions for improvement

regards
Dave
