[offer] Lotus Symphony 1.0 (SCP, IMG, IMZ) [5.25]

callmejack

This is Lotus Symphony 1.0 for MS-DOS


The software is copy protected : Program and Help disks have strange structure



Floppy images in SCP, IMG (derived from SCP) and IMZ format. Note that due to copy protection, IMG and IMZ may not work.

Wow, thanks very much.

I also have original diskettes.

I compared it with yours.
Except Help disk, Program disk, all disks are identical with mine.

Program disk is untouched but different S/N and track 40 with mine.
(I think Program disk is also verified.)

Your Help disk is broken on unused sector.
Anyway I attached it.

Does this differ from the one already on Winworld?

ibmpc5150

Program disk on WinWorld is modified.
It is impossible to recover (restore) as original untouched without original disk.

I dumped it about 4 years ago.
I was sure it is original.

Thanks to callmejack, now it is verified perfectly.


I think Lotus Symphony 1.00 (5.25) (COURSEW) is unnecessary on WinWorld.

There is no Coursew disk on mine and callmejack's disk.
That means Coursew disk is not default disk on Lotus Symphony 1.00.

Coursew disk should be removed separately.

@ibmpc5150 thanks for the fix for the Help disk. Did you fix my copy or post your copy?

@callmejack

I attached my dumped disk in 2018.
I compared it with yours.

callmejack

Is there a risk that your copy of help disk would not work with my package because it has a different s/n ?

@callmejack

I wonder you seems not to read this carefully.

"Your Help disk is broken on unused sector."
*Unused sector, Unallocated sector by FAT

I mentioned unused sector not used sector for any files.

Unallocated sectors are filled with 55h.
But your disk has error on a few of unallocated sectors.

My attached file is same as Lotus Symphony 1.00 (5.25) (HELP) on WinWorld.

I have read carefully but I’m thinking about something else. The only reason I see why Help disk is copy protected is that it provides a way to have a backup of the copy protection (which is on the program disk) without needing to have a supplemental floppy disks (like named Program backup). Now if I take your Help disk, which probably has your serial number, then will it work with my package which has a different serial number ?

callmejack

@ibmpc5150 it could well be that those “unused sectors” contain copy protection data and therefore it’s normal that some sectors seem to be broken.
