These straps are there to put all drives outside of the ST (as the 260ST...)

Thanks JeffThen I'll continue to trust my schematics-reading skills (as I see Dal also did earlier in the thread). The pinout at http://info-coach.fr/atari/hardware/int ... _Connector is thus valid for 260/520ST, only, but not STF or STE models (by default).

A non-twisted flat cable with dual connectors seem reasonable to use if the HxC is configured as drive B. Although all suggestions I've seen have so far mention creating a new cable connecting to the external port I haven't understood why, yet.

I see no problem at all to do this. i have done this myself several times.

Any thoughts? Image of cable with gender changer attached.

We now need a good line on the board for DS0 and DS1. These can be found at W301 (DS0) and W300 (DS1) handily located near the sound chip. Flip the board over and remove the solder from pin 1 at each of these points using a vacuum pump:

Just lazy looking at documentation
I have Hxc Floopy Emulator Rev C (USB type).
Is it possible to select by software
- enable / disable HxC (i.e. if disabled HxC has its output always TS)

You need one double toggle switch (according to Wikipedia it is called a DPDT http://en.wikipedia.org/wiki/Switch and it normally looks something like this):
You have to cut pin 19 and 20 of the sound chip and solder a wire to it. Each wire goes to two contacts on the switch. One middle contact of the switch is connected to drive A select, the other to drive B select:

That is all.
Warning: doing it wrong may well kill your sound chip.
