Howto read Turbodos floppydisk with 22disk or cpmtools?

[fritzeflink]

Explanation: I got a lot of documents and floppydisks for the Philips P3000 system (P3500 and P3800).
They run Turbodos and the default filesystem on floppy is include in the 22disk definition thanks ChuckG.

BEGIN PHI4 Philips PC-3800 TurboDOS - DSDD 96 tpi 5.25" (even P3500)

But there are a lot of floppy disks which are not in CP/M filesystem - they use Turbodos filesystem with Sectors 5x1024.
As I read in the docu the Turbos directory structure has differences to cp/m.
I'm new to turbodos eben I had a P3500 20 years ago. making images of all floppy disks with IMD is no problem, but I like to extract all files on the floppy for save.
The images I made are on the shutdown system in the basement.

Question: Is it possible to convert or read the Turbodos floppy disk like CP/M disks with 22disk or cpmtools (on Windows) ?

You might try Uniform-PC. It has a few TurboDOS in it's file type listings.

 

[Chuck(G)]

As I recall, TurboDOS does use a CP/M format directory. Post an image and I'll have a look.

 

[fritzeflink]

Thanks for your reply.

@bolex
With uniform 2.17 I see the Turbodos 1.4 in the .dat-file but not in the menu. So I can't use Uniform to extract the files.
My Uniform entry in config.sys ist AT + SD5" +

@Chuck(G)
The image has BAS-files so there is a lot of ASCII text.

 

[Chuck(G)]

A quick glance at the p35 image shows a regular (TurboDOS-modified) CP/M directory starting at the first sector. Don't see any BASIC file content, but a lot of games, like ADVENTUR.COM, which does have a load of ASCII text. Otherwise, nothing unusual.

Am I missing something? There's probably a 22DISK definition in the registered version that fits as-is.

Here are the diskdefs I used to extract files from diskettes in ADC TurboDOS format:

diskdef adv4
seclen 1024
tracks 77
sectrk 16
blocksize 2048
maxdir 256
skew 1
boottrk 1
os 2.2
end

diskdef adv8
seclen 1024
tracks 77
sectrk 8
blocksize 2048
maxdir 192
skew 1
boottrk 1
os 2.2
end

adv4 is DS and adv8 is SS. AFAIK TurboDOS is 100% compatible with CP/M directory structure. There was some concept of an on-disk ALV vector to avoid delays on initial disk mount, but I believe it was out of band and does not create any incompatibilities. Bear in mind it's been over 35 years since I worked with a TurboDOS system, so this may be incorrect - YMMV, Caveat Emptor, etc.

Hi chuck,

I have the last version of 22disk but didn't find any definition that works.
There are some definitions showing the directory but didn't extracting the files correct.
Above I posted not the right image.

This definition shows the directory but didn't got the correct files.

These should be the information from uniform.dat for turbodos 1.41 format I can't get in the menu

The first rule of reading manuals is "Don't believe what you read". The definition I get is this:

BEGIN PHI5  Philips PC-3800 TurboDOS - DSDD 96 tpi 5.25"
DENSITY MFM, LOW
CYLINDERS 80 SIDES 2 SECTORS 5,1024

END

I haven't yet created a real floppy from the IMD, but I'm pretty sure that it's the right one.

 

[fritzeflink]

Oh yes, that's great.
I played some basic games and save them to ASCII format with 80mate emulator.

I tested with some other floppy disk and one with only 4k free had problems.
22disk shows me an "out of block number" but the floppy disk has some ##BLOCKS.BAD if this is a problem.

 

[Chuck(G)]

You probably should increase DSM - I left it at 320, but it needs to be larger. Since there aren't any reserved tracks, we can compute DSM as

(5*1024*160)/2048) -1 = 399 (if my HP 16C is accurate)

 

[fritzeflink]

Yes, that's it. I'm testing some more floppy disks next day but ... it's ok.

 

[fritzeflink]

Thanks Chuck for your fast help
- now it's time to go to bed as I'm already slipping off the chair.
