Calling FD9F 256 times is one thing: compatible. And you can use the other way of 'patching' the F700 which was suggested; disable the VDP interrupts while loading from or saving to disk. I remember some clubs could build other DiskROMs in Sony-computers... A lot of people have 'patched' their computer that way...

It's a good idea to standardize the new MSX efforts, it will improve their chances of success. But I wonder, how will the Phoenix standard be decided? There have been many discussions about new MSX standards on this list and the newsgroup, but there was never consensus about what new MSX should be like. Some people want full compatibility with nowadays MSX, other people want a machine that will run Linux, some are willing to pay a lot, others want a cheap system etc. So if the Phoenix standard would be decided upon by consensus, I think it is sure to fail. An alternative to consensus would be voting, in that case the question is: who gets to vote? Anyone who subscribes to a Phoenix mailinglist? A selected group? You must understand that I (and probably many others) are a bit sceptical about new MSX projects, since many were announced and none were ever completed. For people to have faith in Phoenix, it would have to be clear that it will not be another dream that will never become reality. Another question: what are the starting assumptions for Phoenix? You talk about Z380, is that a fixed fact or is it a possibility? And when you write MSX, do you mean "something that is 99% compatible with MSX2" or do you mean "something that carries the spirit of MSX" or something else? > Collaboration, this is a good idea of Paco Molla Gandía, Jesús Tarela and >Rafael Corrales Pulido, we need more interested people in making Phoenix, we >need technical support, a new WEB, a FTP server and a new MSX mailing list, >we need translators, and a concrete list of hardware developers and concrete >projects.

MkII wrote: >Killing interrupts or RETing #FD9F (at least someone who also uses # >instead of h!) causes spinning-forever drive motor 8:( I suggested killing interrupts during disk loading, not full-time. And about RETting #FD9F, it's very easy to solve: simply copy the 5 bytes of the hook entry to some memory location and then call that 256 times after you're done loading. But #401F is a nicer way, although it's more difficult. A warning in advance: DOS2's disk change feature won't function well if the interrupt routine is not called. Usually, it counts the time after a disk access. Since it is physically impossible to swap a disk in less than about a second, it's safe to assume the disk isn't changed if the last access is more recent. But if you stop calling #FD9F, time will be "frozen" for DOS2 and it won't detect disk changes at all. Ofcourse, for ESE-RAM this is not a problem, but for floppy it is. To solve it, invalidate the DOS2 disk buffers (sector cache) using the BDOS call for that purpose. >Also, I'm planning to play background music while loading, so I need >standard interrupts enabled. Good luck! Playing music while loading is very difficult... The reason: almost all DiskROMs turn off the interrupt for long periods during loading. So unless you're willing to write custom FDC drivers (and mail them to the UZIX team ;), you'll have to cope with long intervals between interrupts. You could make special music that still sounds nice when played while loading. NOP played some kind of "music" while loading in Unknown Reality. And for Almost Real we had a part planned where MSX-AUDIO ADPCM samples were played while loading, using NOP's SampBox format. This "required" 256K of sample RAM: the 32K version was very boring. This part didn't make it into the released version, because it took too much disk space, required non-standard hardware (256K sample RAM) and it needed debugging. >>That's because the SONY DiskROM has a different "algorithm" for the drive >>LED: it only turns on when that drive is selected.

The motor does stop spinning automatically (by hardware), but not at the same time as the LED goes out. >Yeah. Now I'd like to know the actual causes of the slowdown. What does the >interrupt do in a F700 to slow it down 400%?!?!?!?!? Just an idea: maybe it's only a bit too slow. If it is called inbetween sectors and doesn't return in time, the next sector will have passed the head and the DiskROM will have to wait nearly a full rotation. If this is true, an interleaved-formatted disk would be about equally fast on a F700 and on for example a 8250. Or maybe the F700 DiskROM turns on interrupts more frequently than other models? You could measure this by installing a counter on #FD9F or #FD9A and see how much counts it gets while loading a fixed amount of data on a F700 and on a 8250 (take the average over a few runs).

Yes, but what I don't know is: Does it stop _all_ drives server by that DiskROM or does it take some kind of parameter? It could be that the 8250 DiskROM does more than it should do. I have no documentation for this call, what I know is from disassembling. One document even describes #401F as "nothing (RET)".

So, please don't use this function at all. Thanks for the warning. By the way, do you know a way to find the DiskROM slot ID for a drive under DOS2?

I haven't read your article (or Track at all), sorry. Tsk, tsk, tsk... I even called it "Maarten ter Huurne should really read this" Nah, that's not true. ~Grauw PS. By the way, does anyone of you live near Bussum (Hilversum)??? The guys of Paragon live in Bunschoten, which is quite close, but they haven't got a railway there so I have to cycle, which is still quite far. I believe Patriek lives in Utrecht or so... But he isn't too busy with his MSX lately. Okay, I like the GameBoy Color too (I've got one, upcoming for it are R-Type in color and Asteroids, great games, great looking).

Write your own diskroutines directly accessing the FDC, which leave the interrupts enabled. However, you will need to write a good CRC error check routine in case you miss some bytes (music can take up a lot of time). However, although it is possible: FORGET IT!!! Aargh, to be precise. Awful solution. The ones below are much better. 2. Play a NOP - Unknow Reality-alike kind of sound, or play looped samples on the Music Module / MoonSound. Those will keep playing while accessing disk too. 3. When loading from harddisk in very small blocks it should be possible to catch every interrupt. So make playing music while loading a harddisk-only feature. ~Grauw -- >><< email: [EMAIL PROTECTED] or ICQ: 10196372 Visit the Datax homepage at http://datax.cjb.net/ ...

Re: "philosophical" view of emulation vs real thing

An emulated MSX, even on another computer called MSX isn't a _real_ MSX. And besides, BrMSX doesn't emulate MSX2. What I need is a turboR-emulator which runs Illusion City.

But if you drop the frequency too low you could create an earthquake. Which could be worse. `:P~ Good thing our speakers neither usual DACs can't out- put these kinds of frequencies! `:))) []s, Parn MSX Mailinglist.

I don't know, but I do know the Sony F700 works the same. The drive always stops, as it is not controlled by counting down through fd9f. How it IS controlled, I don't know...Maybe a simple one-shot, triggered by drive-access? If it is a Philips, you could POKE the counter to 1 so it will take only 1 interrupt to stop. But this would not be 100% compatible I guess. Greetz, Patrick MSX Mailinglist.
