Absolutely correct :-)

Love the Michaelangelo reference. I'm curious as to how many others on the

I can claim size 13 feet, so I'm pretty much on the way to being a real
Bozo. Perhap

We are trying to read some floppy disk used on a 1981 Italian Z80

We saved an image with IMD and we know that the geometry of face A is

So this for to read 1st face A:
BEGIN MUP1 Mupid Seite 1 - SSSD 96 tpi 5.25"
DENSITY FM ,LOW
CYLINDERS 80
SIDES 1

And this for to read the other side B:

To elaborate on what I said earlier, consider the following set of
definitions for the CPC-6128 as marketed by Schneider:
BEGIN SCH1 Schneider CPC 6128 Side 1 - DSDD 5.25"
DENSITY MFM, LOW CYLINDERS 40 SIDES 1 SECTORS 9,512
SIDE1 0 193,194,195,196,197,198,199,200,201
BSH 3 BLM 7 EXM 0 DSM 180 DRM
About 5,25" diskettes it seems that its geometry could be based on 128byte
for sector so using FM recording way and 40 tracks for side it could have 18
sectors for track. If I try to format in this way a disk with 22disk program
I instead get 16 sectors for track. Having doubt on this we gone back
