Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.I doubt RGBtoHDMI has the horsepower to do my rotation transform in real time. Started looking at this one... -
Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.No reason for it to be done in software and every reason to keep it in hardware. The card's a bog simple hardware/driver setup...

Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.Don't understand why feedback is required for scrolling, pointer movement and such. CPU knows it's scrolling and feeds the next frame to...

Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.Hoping it will. Thinking at work today, I've decided to map the card from the PDS connector on the MagicBus Card, pretending that four...

Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.Just read my last and it was badly worded. Not cutting off discussion until testing is done, just saying my responses will be delayed...

Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.Not cloning the card actually, just the first few parts of its front end that feed Page Buffer data input to FPGA in place of VRAM. No...

Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.Yep it's mapped to the PDS Slot's address space, but the buffer data will be in VRAM and inaccessible to the CPU for all practical...
