Talk:ND-110 Satellite 9883.21005/Sintran start errors

Hiya, I was going to ask if you have image files of these floppies, as I would like to start working on the emulator again, and especially the floppy and hdd emulation and system booting process. Roger (talk) 16:44, 13 July 2016 (UTC)

I do, but I got these from someone else, and I don't know if I can share the link publically. Please check your email (I hope your email address from the nd100em mailinglist still works). --Torfinn (talk) 19:29, 13 July 2016 (UTC)

If that email doesn't work I can get you two in contact. Roger, take a look at this site. Datormuseum.se --Gandalf (talk) 23:43, 13 July 2016 (UTC)

Disk image

In that image I see things like e.g.

which doesn't seem to be from an ND disk. However, the very beginning looks like an ND disk (the first page of bytes) TArntsen (talk) 13:44, 1 May 2023 (UTC)

Yes, the disk is larger than the image, so there is probably garbage / previous content at the end. Torfinn (talk) 20:08, 5 May 2023 (UTC)

I see. The masterblock (the first page) looks fine up to, I think, byte 1452, after that it's just zeroes, except for one strange "DOS" somewhere in there (the bootloader section is supposed to go on a bit longer):

The directory entry should have been in the last 48 bytes (as this is SINTRAN III version M, otherwise the last 32 bytes), and you should see the directory name there, as in my own image:

000800:

However, the next 2048 bytes start correctly again.It's harder to analyze, but it doesn't seem to have a systematic error in that same part of the page as in the first page. TArntsen (talk) 05:56, 6 May 2023 (UTC)
