"a forum about Atari 16/32 computers and clones" You mean 16 bits and 32-bits computers? That would be wrong, STs are considered 16/32. So no Atari computer is actually 16-bits. You mean 16/32 computers as in ST? That would be also wrong (would not cover the TT-Falcon, etc). So perhaps better: abou...

Ah, I see now what you mean by RF "in the box".

Yes, of course. The fact that the TV/monitor has or hasn't an RF interface won't change a thing.

anyway, the point remains that the main difference is in the tube and not the addition of some RF modulator to the box. I didn't follow the complete discussion, and hence I'd not argue about this. But an RF in the middle can make a hell of a difference. Given the same TV/monitor, different interfac...

SSP and USP are two different registers. Implicit and explicit references to A7 or SP are aliased to SSP or USP depending on the current priviledge mode (user or supervisor).

Yes, you can access and modify USP in supervisor mode using the move USP instructions.

the PAL standard dictates how many pixels there should be on one line, how many lines there should be, etc etc. both monitors and tv's are supposed to follow the PAL standard, the only real difference is that monitors don't have a RF decoder. so if you know the size of the screen and the number of ...

@Ijor: as i said, it's assemble. I was interested to know specifically which assembler. The ones I know don't perform that (un)optimization. Devpac certainly doesn't. But now i think it's better to turn optimisations off and to learn to write them by myself ! It is usually not a good idea, except f...

Both "clr.b,d0" and "moveq #0,d0" take 4 cycles. I got this problem when i wrote 1st Step, in the Gloky's 512 dots screen, compiled with assemble, all optimisations on. Precisely because both take the same cycles, it doesn't make any sense to "optimize". But what is more important, is that both ins...

In first place, use Disk2FDI to read an ST disk with more than 80 tracks. This will at least confirm or deny if your problem is hardware or Bios based. A big ram disk is not a problem ... if you have enough memory :( Another solution might be to create two partial images on the PC. This *might* work...

It doesn't. Two drives are required only for special functions (copy protected disks, Amiga disks, etc). You don't need those features.

Try software that talks directly to the hardware and bypass BIOS. I think Disk2FDI does. You'll need to use plain DOS, or reboot in DOS mode from Win 95/98.

What happen when you insert an atari formatted disk at 800kb or more? My PC can read and write it, but if you try to read/write data above track 80 it gives an error, as it can't access data stored above that track. Ah, this is a different issue. It might be a BIOS issue, but more likely it is a dr...

I'm not sure about St Format. But there are some other cover disks that are "seudo" copy-protected. It is not actually a copy protection, just a custom format for dual ST/Amiga compatiblity. Sectors on the first track are smaller, and one track in the middle "seems" to be unformatted. More than like...

There is only one cable that the 2600 needs, the TV connector. It is not 2600 specific, so any 8-bit (Atari,Commodore) and even STFM cable should be ok. Joysticks are also standard. Again any Atari 8-bit/ST, C-64, etc works in the 2600. PC joysticks don't work. Or you also miss the power adaptor?
