Hollow Earth
“though a longtime Mac-user (since Mac OS 8)”
Ah, a new boy! I helped run the introduction of OS7 when I was working in the Mac business. I go back to system 4 and a bit of system 3, but I used System 6 (and for a while, 5) professionally – including when I was a Mac journalist.
All of which shows nothing more than that I’ve got a few more grey hairs than the eternally youthful Mr Ingram 🙂
