Here’s a little tip for 1541 Ultimate I owners.
The 1541 Ultimate has a nice audio output feature which gives you the real sounds of a 1541 drive as the virtual drive is accessed.
The Ultimate-II came along and some firmware revisions actually offer two 1541 drives. In order to support audio for both drives, the stereo audio is split between the left and right channels.
For Ultimate-I devices with an updated firmware, there is no possibility of a second drive, yet the default settings for the device have “drive A” only going to one channel.
I found my volume increased when I assigned drive A to both channels in the firmware settings.
Not a big deal, but there it is.
