RE[1]: N-key rollover mode?
its not "3 keys" - its related to how the keyboard matrix works. depending on what keys you press at once you will get a shortcut in the matrix which produces so called "ghost keys". it cant really be...

I can't remember what our current thinking on this is, whether we are aiming for a 100% exact C65 keyboard (with matrix collision problems), or to add diodes so that matrix collision can be completely...

It's true that I would love to fabricate the final IC, and that using modern processes, that a speed in the GHz range should be quite possible. Meanwhile, we are running at 192MHz for the pixel clock,...

Regarding multiple bitstreams on the SD card, this limitation is actually in the little PIC controller that feeds the bitstream to the FPGA on boot. We might be able to have some mechanism to switch...

I was of the understanding that the C65 was going to be released as the C64DX / DX64 , because C= had spare D64DX labels from the SX64/DX64 era that were never used. But I have no hard evidence to...

Yes, we will naturally be using the MEGA65 logo, so you can probably expect something that looks like the logo at the top of mega65.org.

They're making their own motherboard so their won't be that DDR blob on there. If SD card access is fast 16MB would be fine I guess. If not, having more memory would limit load time (i.e.: for a game,...

Right, it needs to be a proper name plate like C= had it. Another thing I forgot to calculate yet :)

As in, I should zip up what's there on my dokuwiki and forward it to you for dropping over onto the mega65 domain sites? If so, I'm fine with that. I'll get that underway
