I am a computer veteran from the 1980s who tested Microsoft Window beta version before it went public. Today, I am building devices using Raspberry Pi computers and have created a prototype rover using RPi3A models that can be reviewed at the link below.

The other device I am currently creating is a Desktop PC using RPi4B and running Arch Linux ARM 4.19. So far, it has been the best Desktop OS with sufficient tools to replace my Intel laptop running Windows 7.
