The atr image for the A disk is missing sectors 524, 525, 526, 528 and 529.  These can be recovered from Bellcom disk D005_A.atr.  The first byte of sectors 193 and 256 also seem to have been read incorrectly, as they differ from the Bellcom disk and without changing them the files DRAW2D.MSH and DRAW3D.MSH are not valid tokenized BASIC programs.  The remaining differences appear to be valid differences.

 

The B disk is laid out differently than the Bellcom disk, making comparison a bit harder.  Most of the files are the identical, although the Bellcom disk appears to have additional helpdoc files (25-27), and the manual is split into two parts, suggesting the Bellcom version is a later revision.

 

I've attached a "fixed" A disk.
