What is a Sirius?

Hi Tony,

Interesting, the only discs mine objects to are, surprise, surprise, 1.2Mb

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.

AFAIK the disc controller is exactly the same for SS/DS drives, IE no firmware
changes etc.

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.
