Ok here is a break down of a transaction to read a single logical sector.
It's pdd.sh with debug level 4, interspersed with explanations
Below, to cut through everything, all the actual serial port traffic is
just the tpdd_read() and tpdd_write() commands.
Everything else is just the stuff to a

You may mean that you can only find the .deb package, which is a binary
installable package for Debian. I reassembled the conte
Actually I figured it out. .Deb is an archive. I have the python code
now. Cheers.

The one in the members file area is a Debian Linux install. I can send the
individual files later today if that would be easier.

Python is a script language... Programs only exist as source code.

I can't find a python source, only a python executable. Is there a link to
the python source? Thanks!

Thanks for the reminder and info Brian, I had forgotten that you had done
this.
I can take a look, thanks.

Thank you. The python is probably good. I'll take a look!

Thw software manual is ok but actual working code is better.
Thanks

The software manual actually lays it all out.
pdd.sh does client-side sector access for both tpdd1 and 2

I'll send it your way when I get home tonight. It's in the Python code too so
if you need it right away you can download that one. It's just the responses to
read requests, but it will give you the general idea.

Thanks for the offer Kurt.
I'm specifically after TPDD1 stuff, so that might mean mcomm sardine code?
I could also just start writing code to see what works.

Steve,
The Sardine code in mComm has code for responding to the TPDD1 sectors. I also
have some old C# code for a TPDD client that I used to make copies of some
disks. At the time I wrote it I only had a TPDD2 (now sold) so it probably
isn't what you are looking for, but I could send it your wa
Hi,
Does anyone know of an example of tpdd1 sector access code?
Thw software manual is ok but actual working code is better.
Thanks
