[Techtoolslist] Samdisk looks very promising...

Do I need the service disk to format my machine to use 6.1?

HOWEVER, this also happens with BOTH of the original 6.1 floppies I have.

some dip-switch setting?) I think the 9100 assumes the HD still to be

THINK that this was only just to indicate to which system this set was
delivered or that it "belonged" to the 9105.

I too have had success with SAMdisk - extracted the TTL original 6.1
floppies from the zip file and was able to write them to fresh floppies
(with errors ignored by SAMdisk) and then able to boot my 9100FT with them.

What appears to be serialized is the TTL 9100 6.1 SERVICE disc, these are
matched to their machines and I did not work from a backup copy back in the
early 00s when this discussion was on.

I'm going to look inside that file (HexEdit) to see if the serial spot is
obvious or not and if so, try setting it to 0000 or FFFF to see if that
clears it.
