All Davidson titles should be loaded in "read only" mode with no acceleration patch.

This is really weird: It tries to UNLOCK an already unlocked file and if it succeeds, it behaves erratically but does not harm the disk in any way. Write-protect it (again) and it works (again).

 

@SoulBuster You should set Altirra's default disk mounting mode to R/O (Tools->Options...->Media->Default write mode: Read only).

Data Perfect v1.2 (1982)(LJK Enterprises)(US)(SCP BAD, NO ATX)[disk]

 

The disk was damaged.  I took 4 recordings of both sides in case someone can do something with them.

Fixed disks (original disk format repaired):

Data Perfect v1.2 (1982)(LJK Enterprises)(US)(Side A)(40 column side)[f].atx

Data Perfect v1.2 (1982)(LJK Enterprises)(US)(Side A)(40 column side)[f].atr

Data Perfect v1.2 (1982)(LJK Enterprises)(US)(Side B)(80 column side)[f].atx

Data Perfect v1.2 (1982)(LJK Enterprises)(US)(Side B)(80 column side)[f].atr

 

Thanks to @burkhart87 who had dumped the same version some 15 months ago (but only as ATRs).

I copied the missing and bad sectors from there.

BASIC REV A. did not fix the Atari Logo screen problem.

I remember another program which had the same behaviour but unfortunately I don't remember which one it was. This was fixed and if we find out which program it was, we could search for the documentation of the fixing (here on AA or elsewhere).

 

@www.atarimania.com do you remember which other BASIC program (IIRC also on tape) had a corrupted Fuji logo when loaded?

Kingdom and Biorhythm probably. Blackjack as well?

Thanks, it was indeed Kingdom.

After reading the Kingdom post, I tried it myself and your tape works fine (at least in Altirra) with BASIC Rev.A - even on a PAL XL:

Same here.  I use the XEGS OS, so I missed it.

Basic Algebra (1979)(Atari)(US)[cassette]

 

Man I hated doing this one, did not like it in High School either.  I was able to answer questions through lesson 13, after that I could no longer do them in my head and only verified what was printed on the screen, and guessed at the answers.  Too much work involved to calculate them out.

 

These are as recorded with no edits other than clipping the noise off of each end.  I only saw a couple of glitches during review, but they were during transitions and I left them that way.

Counseling Procedures (1979)(Atari)(US)[cassette]

 

These are as recorded with no edits other than clipping the noise off of each end.

 

Anomalies in this series listed below seem to be manufacturing errors rather that glitches.

During the gap between lesson 1 and 2 there is an erroneous stop.
The end of lesson 4; the audio is a little off.
The end of lesson 5 does not stop when (PTGO) is printed and the lesson just goes to the end.
The end of lesson 8 stops prematurely.
The beginning of lesson 9, when it spells out Dorsett, the "Do" prints and is cleared and then the real screen starts.
The end of lesson 9 stops prematurely.
The end of lesson 10 stop prematurely.

During the gap between lesson 11 and 12 there is an erroneous stop.
The end of lesson 16 stops prematurely.

 

Possible glitches

Lesson 11 has a glitch at 6:26. It does not interfere with the lesson. Leaving it alone.

During transitions there are a couple of glitches.  These seem to be normal and may not be glitches at all, but rather manufacturing defects.

My previous cassette player died and I bought a new one.  

 

These last few Dorsett Tapes have been recording so well with the new cassette player I decided to re-do the others that I repaired or graded previously.

 

I was able to improve the recording for Spelling and updated it.

Can you please redump side B of this disk (not the one in the Math pack)?

 

Either somebody overwrote side B with data from side A or you accidentally dumped side A twice.

Thanks @DjayBee, It had to be me.  Everything I still had around, including deleted files shows side 1.  Re-recorded it and it is a different disk. Sector 720 is still bad.  It would not clear even with -p, but it does not look like anything important is out there.

 

If anyone got it before, get it again.
