Why does the Commodore 1541 disk drive keep spinning? @tynemouthsw

This is a bit of a strange issue that came up during some recent testing by Tynemouth Software.

It only happens if you load the PRG version of Rodman from a 1541 disk drive onto a VIC20 and run it immediately before the disk spins down.

When you do that, the disk activity light goes out, but the drive keeps spinning. The game runs fine, it is just the disk drive that behaves oddly.

Check out the cause and how it is triggered in the post here.
