How did you manage to do the no-click thing? As far as I know, on Amiga's it worked because the drive ignored the command to move the head to an unexistent track, but on all PC's, the controller will not let the command go through if the track is invalid. That's why you have the click on AROS.

Good, when I get other A1 or other OS4 machine, I left my SE to fileserver. So I need working LAN.

I am smart enough to figure that out. But since I have dial-up, everytime I have to:

1) dial-up, (7 cents connection fee; 1 minute connecting time)
2) download the files (about 600k to 1M; 3 to 4 minutes)
3) hang up
4) work on them
5) dial-up (7 cents connection fee)
6) upload (about 600k to 1M; 4 to 5 minutes; 1 minute connecting time)
7) hang-up

How long does it take using a floppy? Well, you tell me The other option is burning CDs, which you know that story.

And please don't tell me to upgrade to cable internet to transfer LaTeX files! And no I can't use mass storage, it doesn't work on A1-SE.

See, something that may be obsolete to you, may be crutial for others.

When I want to do a review about some OS4 game/software etc. I type it on the AmigaOne. Being able to save it also on floppy as extra backup would be really handy for me. Or with code, besides on the HD it also can be copied to a floppy disk for extra backup. Instead of firing up the laptop and start the FTP server. USB memory sticks don't work so this would be the next best thing for me.

Can AROS access my Amiga 880k disks?
is there a dms or some kind tool on AROS to save this disks? as disk image?

I need to move all my disk over to ADF or DMS!

Would be nice if it could read/write Amiga formatted disks (as in 880K DD or 1760K HD disks).

Not possible.

Not without the proper hardware and drivers. The problem isn't the operating system, it's the floppy controller.

How about just formatting a RWCD and using it as a big floppy?

The CDRW format on AmigaOne is not campatible with Windows format. So, it's not good for file transfer.

But CDRW formatiing as a big floppy is very good for backing up on the A1 itself. I use it and I like it very much.

It seems that there's some way of reading Amiga disks with standard controllers using two drives http://www.oldskool.org/disk2fdi/

USB joypad support is still being worked on, but there same applies like the memory system - it isn't essential. I am quite confident, though, that it will be in the final release.

Does anyone know if you can get a gizmo or something that will allow you to convert standard ps1 joypads to USB?

Or alternatively, will be able to use the joypads directly without modifications?

This was a few years ago so I'm a bit fuzzy, but I believe what I used was a move absolute command to track 0 followed by a move relative command in the outwards direction (-1 I think - I haven't looked at the intel datasheets in a looong time) followed by another move relative in the opposite direction. The trick is that when you do the relative seeks you also need to first enable the spindle motor register and then very quickly disable it afterwards. That causes the dischange status bit to update itself, but the motor enable bit is not on long enough for the motor to actually start running. It does cause the blinkenlights effect though

IIRC the net effect is that the drive would click 2 or 3 times and then go silent. It might have been a quirk of the chipset in the motherboard I had, I never got a chance to test it on other hardware bebause I had a hard drive failure and lost the code (plus my entire fledgling OS) before I could release it as an addition it to my GPLed fdc library. Taught me the value of backups, that did

Thanks Hyperion

As always a good work! Keep working to the os and then concentrate to the other stuff like books sdk documentation

You should know by now that Amiga disks needs an Amiga disk drive which is abale to change the rotation speed. So even on the A1 if you want to read your old Amiga floppies, you'll need a Catweasel. OS4 drivers exist of course.

Umm, I don't think you understand as much about the Amiga drives as you think you do.

Speed has nothing to do with the format. However, limitations in the hardware related to the bit-rates necessary for HD disks has everything to do with it. I found a lot of this out a number of years ago when I had considered writing my own trackdisk.device that would have given even higher capacities than what a lot of the ones on Aminet did.

I got put straight by non other than Ralph Babel when I asked him some questions about his Amiga Guru Book. And a lot of the rest of it I picked up when I went looking for an HD drive for my old A500/A3000 systems I used to have.

I can't recall exactly, but one of the custom chips, even on AGA Amigas, had a bit-rate limitation because of the type of chip (they were NMOS chips, not CMOS or even regular TTL) and the design of the portions that handled the read/write bitstreams for the floppy controller. IIRC, the bit rate necessary to do HD disks was about 5% higher at the standard 300 RPM disk speed than the chips could do. So the simple solution was run at the same bit rate as DD disks, but cut the disk rotational speed in half to 150 RPM.

EVERY standard Amiga formatted DD disk is 80 tracks with 11 sectors per side for each track, for a total of 1760 sectors on the disk to get the 880K capacity. HD disks just double the number of sectors per side to 22 from 11 to get the doubled capacity. The number of sectors on track 0 is the same as on track 79, and the bit rate versus time/RPM is the same ragardless of where the head is positioned, with no change in the RPMs.

Sounds to me like you might have mixed this up with the old Mac drives that really did do variable speeds according to what track you were reading/writing to. One of the reasons why it was so difficult to read those formats anywhere but on an old mac.

The Amiga's limitations always had to do with how the sectors are written to the disks. PC controllers are designed to do sector reads/writes, not whole tracks like the older Amigas did. When an OCS/ECS/AGA Amiga writes out a track in native format, it writes all the sectors in a chunk, with the gap placed after the last sector. A PC controller gets confused by the fact that there are NO GAPS between the sectors and tries to read the whole track as one sector, which obviously fails, or has trouble locating the sector it wants because it counts the gaps to figure out which sector to get and seems to go into an infinite loop of sorts trying to read the disk. Though it was possible, as can be demonstrated on a regular x86 PC with two HD floppies, to make the PC controller read an Amiga disk through the standard PC controller without any special hardware.

In the case of the A1, I was asking because I had hoped that at least part of the limitation in the PC floppy controllers was somewhat driver related and that the OS4 team could have hopefully come up with some trick to make it work anyway.

Yes, I realize I may have to buy a Catweasel as I'm hoping for something that is likely not possible. The biggest reason why I'm hoping this is I am RAPIDLY running out of PCI slots because of having to buy extra parts to fix things on the motherboard that should "just work". That got old when I had to buy the IDE controller to get DMA working, and before that it was the sound card. Now I may have to buy another card.
