Re: Mobsie`s collection
today i open ALL my carts to see the different kind of tech.
I found 5 different solutions.
Here the pic`s. Is not for all interesting but maybe for some one.

Re: RND function
Hi Carlsson,
have you test the BIOS RND function in assembler because i need a RND function?
And when the BIOS function work okay why not use.
thank you

Re: WIP: Reversi
Some more information from an TI thread in AtariAge, maybe interesting. Here the same, only fast machines can overrun the VDP. Only access in VBI i save. Here the text: The VDP delay question, we had a huge investigation on the Yahoo group a few years ago. I'm the one who put a logic analyzer on the...

Re: WIP: Reversi
if you look to the AppendexE from the TMS99xx pdf and read the examples for the TMS99xx cpu you see that here are also NOP`s and the comment is "dont write to fast" because this CPU is also very fast. On Z80 machines this is not needed because the RAM access itself is so slow that the TMS is always ...

Re: WIP: Reversi
Yes, 6502 at 1 Mhz are Z80 at 4 Mhz (also the A version) 6502 at 2 Mhz is like Z80 at 8 Mhz. Yes, the Z80 has more register and more instructions but most take more cycles then on 6502. The RAM Access is also most slower on Z80, and the 6502 need fast Ram. But on all Computer or Console this errors ...

Re: WIP: Reversi
Yes, is a difficult step from emulator to real hardware. For the CV is more difficult because the fast CPU and RAM in combination with the TMS.
Most don`t understand how difficult it can be.
But we learn on every new machine, and we all wait your GREAT game.
So take your time.

Re: WIP: Reversi
hi, thats like i do it. the first transfer i made with screen on, in the map-demo version you have. This make the errors on reset, i have change this. ALL other i write ONLY in the VBI. I know from TI and Memotech programmer that this must work, the memotech is the fastest Z80 machine with the tms c...
