Courage and good luck !

I wasn't able to answer more fully, nor even now.  I just spent a week 
in the hospital.  giant kidney stone and massive infection.  First few 
days were intolerable levels of pain.  I am now on 2 weeks of 24/7 IV 
antibiotic infusions.  Bizarre little pump that I carry around, but, 
at least I'm carrying it around at home, instead of the hospital.

Well, when in doubt, check 22Disk, right?  Here are the CP/M formats:

BEGIN OTR1  Otrona Attache - DSDD 48 tpi 5.25"
DENSITY MFM, LOW
CYLINDERS 40 SIDES 2 SECTORS 10,512 SKEW 2
SIDE1 0 1,2,3,4,5,6,7,8,9,10
SIDE2 1 1,2,3,4,5,6,7,8,9,10
ORDER EAGLE
BSH 4 BLM 15 EXM 1 DSM 181 DRM 127 AL0 0C0H AL1 0 OFS 3
END

BEGIN OTR2  Otrona Attache - DSDD 96 tpi 5.25"
DENSITY MFM, LOW
CYLINDERS 80 SIDES 2 SECTORS 10,512 SKEW 2
SIDE1 0 1,2,3,4,5,6,7,8,9,10
SIDE2 1 1,2,3,4,5,6,7,8,9,10
ORDER CYLINDERS
BSH 4 BLM 15 EXM 0 DSM 386 DRM 127 AL0 0C0H AL1 0 OFS 3
END

I have samples on file--and probably the MS-DOS ones somewhere.  What's
interesting is that the treatment of the second side is different
between 48 and 96 tpi versions.   The EXM difference is also
interesting--could be an error, but I've received no reports on it.

WOW!  Sorry to hear about this, and hope the surgery gets 
the stone out and you recover well and quickly!

Otrona / Hospital

2017-11-02 Thread Fred Cisin via cctalk
I was not able to get access to any of my notes to more completely answer 
Eric's question.


Short answer: NO.  Otrona did not have two different obscure numbers of 
tracks for their disk sides.  On the limited number of Otronas that I 
encountered.  What I encountered was very straight-forward WD-like 
ordinarty disk formats.  IIRC, they were 10 sectors per track, with 512 
bytes per sector.

There were 40 cylinder and 80 cylinder.
There was a CP/M, and an MS-DOS.
I don't remember what the distribution of those formats was, although I 
specifically remember a 96tpi (800k) MS-DOS.


Ironically, the first one that I saw was a doctor at a hospital.
To flog the point about portability, Otrona did an early ad with a Chaplin 
imitator trying to carry a card table with a PC on it down steps in front 
of a building (capitol?)  IBM claimed to own Chaplin (and did apparently 
pay royalties to Chaplin estate), although Chaplin himself was not a big 
fan of biug corporation.

THEN, in 2 weeks? they will operate to try to remove the stone.  They are 
hoping to do it with trans-urethral laser, with lithotripsy as a fall 
back.
I had not prepared for being in the hospital, so only had a phone (Samsung 
Galaxy S4), and it wasn't until the third day that I was able to wrangel 
access to my pants (and pocket contents)

I think that I will recover.

THANK YOU to the folk who wrote to me with good wishes!
