Commander X16

Yes, if no DIP daughter-board with a surface mount 65816 and 16MB of RAM is developed, that becomes an issue with the Dev board. But if I understand the FAQ correctly, that sounds doable. Indeed, once the GS board designed is finalized, I'd recommend hammering that kind of DIP daughter-board out an...

After learning about the internals of the 65C816 (and having learned 8086 assembly years ago), I have decided to call the 65C816 an 8/16 bit processor. It's mostly 8-bits, but can act like a 16 bit CPU when needed. It's actually both. Well , three. I find writing 65816 assembler it's best to pick a...

The reference version of Chip-8 is the Cosmac VIP version, there's commented source in an issue of VIPER I think.

I would start with the Commodore VIC-20 User's Guide, which does an excellent job teaching BASIC. Then I'd modify the machine-specific instructions to work with the Commander. I did a pretty exhaustive look over the manuals a while back. The two that stood out were the Vic 20 and the Sam Coupe as b...

First decide what it means. What is your "target market" ? Commodore machines tended to have two manuals (according to Bagnall's book this was pushed through by the engineers for the Vic 20). One was "An introduction to programming" which tends to have a very cheerful bunch of th...

Don't do it on the X16. Initially. There's a reason for this. There are countless C64 tutorials, books and tools available for nothing (there are for the X16 just fewer) which gives you a big choice at all levels, depending on how much knowledge you have ; everything from absolute basics through to...

My (Neo6502) version, not quite complete. No Brains .... and obviously no collision detection which makes surviving easy but scoring a bit difficult. https://www.youtube.com/watch?v=tzpN1NQkSEk Oh! I missed that - it looks fantastic! Now playable :) https://www.youtube.com/watch?v=wik5QBKo2SI

If you can do your filling using horizontal lines it should be *much* quicker, because you can just blat a series of bytes at Vera. Incidentally, I wrote an algorithm for Stefany Allaire's machine which is a Bresenham Approximation, it's a cheat variant of Bresenham where basically everything is sca...
