I remember the heated debates on SCSI vs PCI in 1990s personal computers ... and today I learned that the _real_ PCI is a Panel Call Indicator. And I now know how it sounds!

I've also found out about the Evan Doorbell tapes.

The perfect way to start the week!

That's why the world needs Mastodon.

Thank you, Connections Museum. So glad to have discovered you.
