Here we go again.. another attempt at building a SuperSID Monitor and data logger on a Raspberry Pi computer.
Current running on a netbook with Windows 7, the netbook is old, often forgets is drive and crashes, and most importantly, the data being logged by the provided supersidv1.2.2 software seems to have a decreasing averaging issue. After a few days the Power Spectral Density (db/Hz) seems to go down to zero and then into negative numbers.

This graph was captured just after a restart. All of the Y axis values look good, ie well above zero!
So.. the SuperSID on a raspberry Pi project begins again!
We have a Raspberry Pi 3B, a 16GB microsd card, a USB External 7.1 Channel Sound Card

We went to https://www.raspberrypi.org/software/operating-systems/#raspberry-pi-os-32-bit and downloaded Raspberry Pi OS with desktop Release date: January 11th 2021 Kernel version: 5.4 Size: 1,171MB.
It was extract to a 4GB .img image file.
We then flashed it to the 16GB microsd card using balena etcher … thattook about 10 minutes.
That was installed into the raspberry pi along with an HDMI video cable, an ethernet network cable and the USB audio adapter, and started up.
After configuring a new password, configuring location and language and keyboard, it started an OS update. That took about 20 minutes, and rebooted.
We then went into the builtin apps to the raspberrypi config menu and enabled SSH and VNC.
We were able to SSH in remotely using a windows program called putty, and also from another linux server.
Great. Remote access up and running!
Now lets try remote graphical desktop access. We fired up a windows VNC viewer (ultraVNC v1.2.2.4) but that failed with a “no supported authentication methods” error.

**UPDATE***
Got it! Apparently all VNC is not alike. To access the Raspberry Pi Raspbian Buster VNC server, one MUST use the RealVNC client/viewer… NOT ultravnc which has been my default.
Awesome! Now we have full graphical desktop remote access to a linux install!

**UPDATE** After a few more hours of installing libraries, dependencies and packages, and trying to troubleshoot, we concluded that using Raspbian buster 20210111 with the PulseAudio sound server, would *NOT* work with the existing python code, which was designed around the older ALSA sound system.
