Ultimate 64 usage and configuration
Install the ARM2SID in the primary (lower, SID-1) socket and SID2 in the
secondary (upper, SID-2) socket in your Ultimate 64. Connect ARM2SID and
SID2 with the provided special cable harness for Ultimate 64. The small
connector with all pins populated belongs to ARM2SID and the connector
with only 5 pins populated to SID2. The one longer wire connects to left pin
on SID A[5..9] dual pin header in Ultimate 64.
Take care for the proper ARM2SID and SID2 orientation! Wrong orientation
could damage your computer!
The SID A[5..9] brings an addition address line to the ARM2SID to recognize
more different addresses where internal SIDs/SFX could be positioned. It is
controlled by Ext DualSID Range Split setting of Ultimate 64 configuration.
There are some setting common for all ARM2SID modes and then you have
to configure Ultimate 64 and ARM2SID with its configuration utility for
required mode of operation:
•
Standard 2 SID stereo
•
3 SIDs
•
SID + SFX Sound Expander
