I would like to try to recover more of your files. If they were written on an 810, they may be off-track or skewed.

 

If you are still local to the Bay Area, I can pick them up (one at a time, if you like) rather than trust them to the USPS or such.

No, I'm no longer in the Bay Area, but I could send them to you in batches. What address should I use?

Has anyone been able to load & run the scenario editor and/or load 1943/1944 data files?

Either they are corrupt or im loading these in incorrectly? (using Altirra and win800plus for convenience)

The 'EF 1941 scenario editor .atr only has a text file in it called NOTES.TXT that starts with DESIGNERS NOTES
It has no executables and doesn't boot. No, it also has EFTFNT.DAT in it.
The '1943-44 scenarios for eastern front.atr is a DOS 2.0S atr with three, I guess, game saves,
EF42STLN.GRD
EF43KRSK.ORL
EF44MAY1.SAV
It isn't corrupted, has DOS.SYS and DUP.SYS, boots fine.

Those three files are intact. I don't know how to load saved scenarios.
Since I don't know how to load them, I can't tell if they are good.

I have a lot of old Atari floppies. I sent them all off to a fellow at the Atari museum. He read what he could and sent them back, including a CD-ROM with all the files he could pull off them. As you can see, they were pretty badly corrupted.

That was probably Curt Vendel.  If he couldn't read them, then I don't hold out much hope.  Then again, Bob is also quite the Atari wiz so maybe he can work some magic?

Yes, it was indeed Curt Vendel. Still, let's let Bob take a stab at it.

Thanks - pressing Option on the main screen calls a disk loader but i suspect this is done differently as its not responding in this way.

Bob, does your 810 have "The Chip" installed? I found that they can help in recovering bad floppies :)

I think I have a 'Chip' in a bag somewhere - none installed that I know of.

What would the Chip do for you?

Worse comes to worse, I'll just build my own 'drive' and rip the tracks. I have some disks from OSS that I can't read either, so this project has been in the queue for a while.

As long as there is oxide on the disk, we should be able to read it. If somebody wrote over the data... well...

Along with the Chip, the Archiver/Editor allows different settings to read skewed sectors and sectors with a bad CRC where the oxide has deteriorated some. I have been able to recover disks that were over 60% unreadable into a 100% good image...

You can also read a single track at a time with visual status of each sector.

The Chip mod just changes the 810 rom with a 4k eprom with a couple of wires used for bank switching the 2k segments.

By the way, I might as well mention this here: do you fellows know about the "frozen floppy" trick for recovering old floppies? It's very difficult to do correctly, but it has worked for me.

Never heard of that trick (frozen floppy). I did learn to clean the heads of the drive after every disk cloned though, after finding out that the oxide could be lifted from certain old floppies when using a drive with dirty heads. :P

A clean drive is a happy drive... No, wait...It isn't... I should say "Use a Happy drive that is clean and in good adjustment" :)

I'd say let Bob have a try - and what OSS disks are in the queue :)
