need help with archiving PCW floppies
« on: 16:36, 12 April 13 »
hiya guys, I've just got ahold of a load of 3" floppies which were used on the PCW, and well, would like to archive them if possible before they get wiped and formatted...


The issue is i have 62 of them.


Any volunteers/ideas?

If no one nearer is able to do it, and you don't mind sending them to Spain, I'll archive them as soon as possible and return them to you.

I don't have a PCW... those are 360kb/side, aren't they?

As far as I know, they should be same as 6128's. the PCW 9000 series had double sided drives.

If they are, I guess I can do it; never handled PCW-written disks, but if they can be copied by some CPC copier, sure, very simple to do it. Add me to the list.

I'm working with Habi in creating a nice PCW Wiki, but dumping, scanning and uploading to the web takes a lot of time. I hope we have something you can take a look to soon!

Can't it be dumped with a PCW (or even CPC or Speccy+3...) with both a 3" disk drive and a HxC floppy disk emulator?

The best way is to use a PC+FD1 and Samdisk.If nobody owns this, i can do this with mine (or better , someone else get half and me other half)

Im guessing you can use a Kryoflux board as well. I have my trusty old Kryoflux+FD1 and a "wrapper" version of Lord of the Rings - Game One (its my one and only pcw game  .. "my precious" .. hehe!).

As i dont have a PCW, i have really no way to test it but i did do a quick MFM scan (like i do with the cpc discs) and it reported back with crc ok on side A (and unformatted side B) so i guess it ok and error free. So if the game hasnt already been dumped i can upload a kryoflux dump if you need?

A bit late but nevertheless:

I reactivated my Joyce and did a test with its disks.

You can dump PCW floppies on the CPC with a HxC as B drive by using Discology (for example). You need to insert a dummy PCW floppy image on the HxC, and you have to make sure that the "structural" data of the image (e.g. sector id, at least in my case) is the same on the floppy and on the image of the HxC. Only then will you succeed in copying the floppies, otherwise the HxC will not write the data though it is still pretending to. You do have to check the resulting image file to be 100% sure. As a last step you need to convert the HxC image file to the usual dsk-format with the HxC floppy emulator software.

A bit complicated but it works, and needless to say that copying CF2DD are out of question because the CPCs don't have such a drive.

But how do you "make sure" that the structure is the same?

Good question.

For standard format the answer is easy: Check in advance what kind of disk you want to copy (System, Data, IBM) and insert an empty dummy disk with the same format into the HxC.

Specially formatted disks are another thing altogether. You'd have to read the complete disk info (sector-id, no of sectors per track, gap, etc.) save it "somewhere" and prepare a file on the PC or SD-card, and then copy the disk. That somewhere is the problem as anything that is not done directly on the HxC is much too complicated.

@MaV: Thanks for the info mate!

Alrighty, finally got around to dump the Lotr PCW disc. Attached the MFM dump file and it appears to be 40 tracks long and error free. Hopefully someone can make something from it. Also it looks like to boot the game youll need to load a cpm disc first (like on the cpc ish)  ;)

Has anyone tried this under CPC CP/M +?
I wondered that if it is CPM compatible (and therefore work on CPC) or if it uses some PCW features?

@Cholo: Brilliant! Another game saved for posterity! :) Thanks a lot!

Is the MFM-format readable by the HxC? I have no experiences with it. If so, I'll check the game out in the evening.

@arnoldemu: Most probably it will use PCW features, since the game uses graphics (and I doubt that it uses GSX). I'll try to test it in the evening.

Thanks Cholo!


When I have a little time, I'll be adding it to our new PCW Wiki, and make a tutorial/style guide so everyone can enter info on it.


Cheers!

About the MFM format: alas donno the specs but it should be a common format. The Kryoflux MFM -i4 format is indeed compatible with the HxC and its actually possible by using the "load raw image" to load a DATA format CPC disc directly into it. Girv posted the correct way to load a DATA disc in here (post 24) including the correct options:
Image 3" floppy disks for emulator
Image 3" floppy disks for emulator

Ive tried that myself and it still works .. with CPC DATA format discs .. even though the software has been updated and the options has a newer layout and all that. Once loaded you can even save it back to Data DSK. Trouble is that the Lotr disc is in some PCW CPM format + im 90% sure it isnt compatible with my 6128 as well.

I was about to post the DSK- and HFE-file about one hour ago, but got stuck with playing the game. :D

This gave me the chance however to reread the other thread and notice that the mfm files are created with no interleave, so I converted the disk with no interleave as well.

I was mistaken regarding the graphics in the game. I think I mixed it up with The Hobbit on the CPC. :( The game is text-only as far as I can see.
