Hey everyone,
I bought two of the Nano SwinSIDs to evaluate. I'll bring them to the
TPUG meeting next week. But, I thought you would be interested in
reading about its capabilities (especially Rob). See the note about
selectable filter emulation!

Hi Leif,
there are some instructions in the discussion thread at forum64, but
it's in German anyways.
There are two jumpers:
- set board: this one switches resistor R3 on or off. The setting
depends on the type of C64 mainboard the NanoSwinSID gets installed
to. Some mainboards have an 1k resistor already installed, others
don't. The rule is, older mainboards which had an 6581 installed need
the jumper open, while newer motherboards which had an 8580 installed,
need the jumper closed. With a wrong setting you can't damage
anything, the setting influences sound volume and quality only. If you
want to be sure, look up if the resistor is installed on the
mainboard. It's R6 on older mainboards and R8 on newer ones. If it is
installed, the jumper on the SwinSID has to be open.
- set filter:
This selects the type of filter emulation of the SwinSID. If it is
open, it behaves like a 8580, if it is closed, it sounds more like a
6581. This jumper is evaluated in real time so you can change the
setting within a tune :)
