Re: Modified Drive (old method,) move to positive on failure

If the bit extending the sensor blocking part is missing you'll have problems.

Re: Modified Drive (old method,) move to positive on failure

Ah indeed. Is there anything glued to the black plastic part that slides between the sensor?

Re: Apple II DOS 5.25 in. floppy disks

Disk itself contains short 6502 code and warning that the disk is not bootable at the first sector. The rest of the disk seem to be filled with text. Everything except the 6502 code is XORed with 0x80.

Re: TA ScreenTyper 5.25 in. floppies

diskdef tast
seclen 512
tracks 80
sectrk 10
blocksize 2048
maxdir 64
skew 0
boottrk 2
os 2.2
end

I also had to manually hexedit the directory to remove spaces from the names or the files aren't found by cpmcp.

Re: TA ScreenTyper 5.25 in. floppies

After just trying out things I finally got the files copied using blocksize of 2048.

Re: TA ScreenTyper 5.25 in. floppies

I tried some that had suitable parameters and also tried creating a custom but no luck yet. Should look into what the skew and os parameters really do.

Re: TA ScreenTyper 5.25 in. floppies

Not sure what the secret with cpmtools is but when trying to copy a file it claims the first file on the disk to be out of disk image boundary even tho the file starts right from the first available sector.

Re: Modified Drive (old method,) move to positive on failure

It should do a single seek in and out and report 0 or so, but not move below track 0 again.

It's the only drive on the cable?

And everything still works normally if the head doesn't stop below 0?

Re: TA ScreenTyper 5.25 in. floppies

Ah, you're correct. Downloaded some random CP/M disks and they have similar directory layout.

http://www.moria.de/~michael/cpmtools/

With these I'm able to list files from the disks but extracting them results in incorrectly sorted sectors.

Re: TA ScreenTyper 5.25 in. floppies

Looking through the manual with my almost non-usable german language I don't think that program can work with actual filesystems, other than perhaps CP/M.
