 The current pin name selected will show on the LCD (if connected).
-The pins are identified by : _______ ?
+The pins are identified on the MB SID schematic: [[http://www.ucapps.de/mbhp/mbhp_sid_v3.pdf]]
-To measure the voltage (and test the connection to that pin is good), connect your multimeter's red lead to _____ ? and the black lead to _____ ? and select the pin using the moudulation wheel.
+i.e.
+  * RES# is pin 5 (anti-clockwise from the top left)
+  * CS# is pin 8
+  * A0 is pin 9
+  * A4 is pin 13
+  * D0 is pin 15
+  * D7 is pin 22
+To measure the voltage (and test the connection to that pin is good), connect your multimeter's red lead to the pin and the black lead to ground and select the pin using the modulation wheel.
+For 2 SIDs running from one core (e.g. in MB-6582), both SIDs will be mirrored.

+SID Testtone generator
+This MIOS application generates a simple 1kHz triangle testtone on the SID.
+There is no "MIDI Note On" event required to start the sound, you should hear it immediately after the MIOS bootphase
+In addition, a 1 kHz pulse will be generated on the CS lines to the two SIDs. This feature allows you to test the output amplifier of the
+SID module (unplug SID, connect socket pin #8 with #27)
