Differences between OS65D V3.2 and V3.3

Post by lowrybt1 » Wed Apr 12, 2017 12:31 am

Hello,

Can anyone clarify:
1. what the appropriate calls are for loading\executing the track zero copy utility on V3.2 and V3.3 5" disks (C4PMF)?
2. are the directory tracks/sectors the same for both V3.2 and V3.3 (5" C4PMF)?

Thanks. T

Hi,

For calling TRACK0 on my OSD65 Ver3.2, after EXITing to DOS (A* prompt), I have written a note in my User Manual that it should be :
"CA 0200=13,1 then "GO 0200".
The reason I say "should be" is that my C4PMF hangs when i try to "GO 0200". I believe that my TRACK0 file, on Track 13, is corrupted on both my regular boot disk and my Backup boot disk (I just unpacked the computer a week ago after 35 years of storage and it took me a few days to get it back up and running, so I have little memory of what shape the disks are in. Also,in trying to copy files between disks i have noticed a lot of tracks are un-writable, even after an INIT). Or it could possibly be Track 1, Sector 2 which I believe contains the routine that is run when you perform the above command.

As for the Tracks and Sectors being the same between the 2 versions, I ran the WinOSI 6502 Emulator, loading a Ver 3.3 IMG and then running the RUN"SECDIR" on the Emulator and the same on my C4PMF running Ver 3.2, and the Tracks/Sectors do not appear to be the same, though that statement can't be construed as definitive :-). I have some screen shots of both the sets of outputs if you're interested.

*** IF SOMEONE HAS OR CAN POINT ME TO THE SOURCE CODE FOR THE TRACK0 ROUTINE (Ver 3.2), IT WOULD BE GREATLY APPRECIATED ***
I'd like to see if the TRACK0 program is corrupted, or maybe, based on some reading, track 1 - sector 2 is corrupted.

Thanks

Welcome Andis,

5"
V3.2 Copier/TK0 Util Tk13,1 (01,2 on some disks? 8" )
V3.3 Tk0 Util Tk 6,4

Call $200 (not Cegmon -reloc @ $0300)
Use WinOsi save code tools.Disassemble. osilod. ...

Good luck.
