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. Upd 2012 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)
