The original Macintosh keyboard didn't have an escape key.[1] Or function keys. Or cursor keys. Or a numeric pad, though you could buy one as an accessory. You're supposed to use the mouse.
I used (and refurbished) a bunch of those. But I switched to the Mac full time because of UNIX, not when it ran cooperative multitasking hacks atop a 680x0 CPU.
Yes, but in this enlightened era, we run Unix and recognize the importance of the CLI. Maybe not the best, but it's sure as heck better than the original MacOS.
