Robotron-to-PC HOWTO
      Transering files via diskettes from Robotron 1715 series to IBM PC

 By Dmitry the Zuryanovich, dtz @ xepb.ru, 2:5020/730 (better to /730.730),

 I assume you have Robotron 1715 with two 800k drives and IBM PC AT
(or greater, not PS/2) with standart PC floppy controller and at least one
1.2M 5'25 Floppy.
 
Method I
 [DOS[ You must get 22disk program from Sydex, possible from oak.oakland.edu ->
simtelnet -> diskutils, and Sven's Shubert's .def file with defenitions
of Robotron disks, somewhere from my site (http://xepb.ru/robotron/docs/cpmdisks.zip).
 Install 22disk and overwrite .def file before running 22disk. Then run
it and confugure.

Method II
 [Robotron] Obtain scp-dos.com program for robotron and read/write 360k dos disks.
 You can download image of disk containing bootable system and scp-dos
 from http://xepb.ru/robotron. You will also need copyqm dos
 program from Oakland to write the image on PC.

Method III
 [Linux] http://www.moria.de/~michael/cpmtools/ knows at least two 
Robotron formats; format 17153 works for my R1715/800K/SCP 0006 disks at least.
UPD 2013
For CP/A/800k disks use following for /usr/local/share/diskdefs:
# Robotron 1715 with CPA
diskdef cpa1715
  seclen 1024
  tracks 160
  sectrk 5
  blocksize 2048
  maxdir 128
  skew 0
  boottrk 0
  os 3
end  
UPD 2014
Before trying to do smth like 

cpmls -f 1715 /dev/fd0

you should tell your's FDC to accept 1024/5 SPT disk format.
That is done by 

setfdprm /dev/fd0 QD sect=5 ssize=1024 cyl=80

(but sometimes DD should be used instead of QD)
