Hello, I am working on a DOS menu program in assembly to basically continue a work a started when I was just a kid learning to program my Atari
Now that I'm coding the format function, I need more control over density types and options and need to use SIO instead of the more limiting CIO (it is DOS dependent and I'm using SpartaDos which does not have internal format function other than single density).

My drives all have Speedy installed, so I'm looking for a list of SIO commands the Speedy supports (much like what I found for US-Doubler).

Is there a list of SIO commands Speedy supports that I can use?

After some searching, I landed on this list https://www.atarimax.com/jindroush.atar ... p1050.html
It outlines all common 1050 extensions and their SIO commands, it might benefit others.

There is a manual for Speedy extension with all the Speedy commands.
Also in the Altirra Hardware Manual, there are a lot of informations about the various implementation of SIO commands.

Do you happen to have a link to the manual?

The Altria doc is wonderful, thanks for pointing it out, it has tons of info

You can find it here: https://atariwiki.org/wiki/Wiki.jsp?pag ... 20Upgrades.
I don't know whether there is a english version.
