Hello Edzard...
Let me introduce myself first... My name is Paul, from the Netherlands.. and I'm
building the Old Junior Computer from Elektor... The computer is already up and running
and now I'm busy with the floppy card.... Final step is a memory card ... The goal is
to have the DOS -Junior combination back running... But I'm looking for a version of
OS65D...which is very hard to find... Maybe you know some entries where I can get a
version of this Operating System....V3.3 of the OS would be nice...
Many many many thanks in advance,
Paul Moers from Netherlands.

Hi Paul,
simple googling for OS65D will point you to the UK101 page of Mark
Csele, where you can get an OS 3.3 image. Of course, you need almost all
Elektor articles, as well as the Elektor Computing issues which describe
in detail the adaptions to be made. Problem is of course that the
Elektor OSI computer uses a rather obscure floppy controller and
formatting (some GCR emitted by an asynchronous 6850 that is hacked into
a synchronous mode). I doubt you'll find ready to use floppies for that
beast, so best that can be done IMHO is transferring the sectors one-by
one to the target system, by some serial protocol and then using a
program to throw them on the floppy.

It's FM, not GCR.
Of course, it's not IBM-standard FM. Normally it can
only be read and written on an OSI (or Elektor) system. Given how
expensive FDC chips were when OSI designed their floppy controller, I
suppose it can be considered a clever hack, though nowhere near as
clever as Woz's design for the Disk II controller.

New subject: Elektor and OSI's OS-65D (was OHIO-DOS)
Seems http://osi.marks-lab.com/ has some disk images of v3.3. Might
not be directly usable, but you probably will be better at judging
that than me. Else, it seems a great starting point to get where you
want.

Sander Reiche (also from the Netherlands :))
