Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.Incremental updates I understand, Data in VRAM iis refreshed when it's accessed, so it remains the same until actively changed by the... -
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.COOL! Didn't know that'd be possible. I've been wondering about doing something on the order of a MacPaint program with a full screen...

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...

Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.Interesting, but the Page Buffer is built up in VRAM sequentially in alternating cycles split with other CPU activity. AFAIK it never...

Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.Can't see the traces yet. I need to test this card, the one I got recently was listed as tested good and will be set up first with...

Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.Pi Zero's been approved as a good proof of concept platform. Just checked, Pin 5 is a data line and not tied together. Wouldn't expect...

Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.Bad news just got worse from the serial output point of view, but maybe a whole lot better from mine? Pretty much verified the...

Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.I'll give it a shot: That's pretty much it, butPi Zero 2 W will probably only do "every so often frames" which may or not be rotated...

Trash80toG4 replied to the thread Page Buffer Capture from Radius FPD/SE VRAM Input - First baby step to cloning Card.I guess I should explain the point of the overly complicated wire wrap prototype. Aiming toward doing a PCB set up like so. To run...
