Uzebox Forums

nice work.

I can confirm that the SD card tool formats in a way that makes cards work faster than the format tool built into at least Windows 7. Newer versions of windows may have improved that but Win7 does it sub optimally. I have not tried recent cameras but I also know that an old Casio I had formatted SD ...

Sorry - It is in the CSD not the CID regsiter. Field called erase sector size. Though in my quick google search to find my mistake I did see something that said this is only valid for SD card and the XC and HC cards use a different approach. The fact that cameras and other devices know how to format...

Doesn't the card tell you itself the memory layout via the extended CID request thingy?

drag soldering with a flat or hoof tip unless you have a lot of experience. also use leaded solder - you need to have the technique down pretty well to succeed drag soldering with lead free. have the tip at a shallower angle to the pins you are dragging past - so the surface tension is pulling the e...

There is something very wrong with search engines these days.

I'd guess that the Uzebox could do it >20x faster than the C64 if you reduced the screen height down to a line per pixel. (I think the mandelbrot picture is about 24 pixels high).

Probable about 2x faster than the C64 if you kept full height screen.

The PC-Engine was just an 8 bit machine. It was a super fast 6502 variant. Same CPU the C64, Apple and BBC used. It was about 4x faster than the original 6502. So the Uzebox is a much faster and better ISA than the PC-Engine. However as you know it has to spend most its time making the TV picture. S...

I recall "Sprinter" from the AVRFreaks forum saying that at one point a few years ago that GCC had changed something fundamental in how it worked. It made optimisation better for giant super scalar CPU but made it worse for AVR. That might be the reason the official version stopped at 7.3.0

I am not sure how other modes did it, but T2K which was the first interrupt ended scanline mode did not use the timer counter interrupt to end the scanline. It left that one untouched. It used the OVERFLOW interrupt. and set the counter to [0x10000 - time]
