Carey,

How were you able to download the v2.01j version from the OmniFlop web
page?

Thanks

Bert

Which one are you talking about?  v2.01i or v2.01j?

The 2.01j isn't up on his website yet, although you can download it by 
changing the filename.

The 2.01i can't read my 5.25" 40 track 360k dsdd OS9 disks, although it 
could do other CoCo 360k disks.  It thought they were some new weird
format 
it had never seen before.

v2.01j can read them.

So maybe B&P have a slightly unusual format that 2.01i just doesn't
like.

I was taking a look at my os9 v2.06a program source and maaaaan that
code is 
ugly...[grin]

It looks like it's doing the 256 byte sector stuff in a way that XP's
dos 
box doesn't like.  That's why it doesn't work.

But I don't know if I can get it to work.  It depends on just how many 
int13's Microsoft has disabled or chose not to emulate.  People have
been 
saying for years that XP's dos box (cmd.exe & command.com) are extremely

broken, so it's probably the needed interupts are neutered.

I'd have to hunt up my old Turbo C++ 3.0 too, to work on it.
