What is a Sirius? - test-drb@ccmp.vtda.org

6 Jul 1999

Hi Tony,

...
 My Sirius is very 'fussy' about the disks it
will handle. It won't use
most 360K disks. It will work with '80 track' disks.... 
Interesting, the only discs mine objects to are, surprise, surprise, 1.2Mb
ones.

I'm pretty sure that the discs I used in mine were a mixture of 48tpi and 96tpi
media, no problems with either type here.

...
 ....One day I'll get some suitable drives to
experiment with and see if I
can get it to handle DS, or if there are other changes. 
AFAIK the disc controller is exactly the same for SS/DS drives, IE no firmware
changes etc.

...
 Any ideas which version of MS-DOS that would be? I have
1.25 and 2.2 I
think somewhere. 
OK, I DO have a copy of 1.25 which will access the hard drive. However since
it's v1.25 it's only of academic interest - I also have a copy of (I think) DOS
2.11, complete in "Victor" colours, but that refuses to see the hard drive at
all. I'm told I need a different version of 2.11 which includes support for the
hard drive.

  TTFN - Pete.
