 Maybe that's the whole point, hmmm? The PCs have dedicated crt controllers...the Mac didn't. These were highly programmable, had diverse textual and graphical modes.

 Absolutely. And that's the beauty of it (it wasn't all that hard to distinguish actually. A marvel on such early equipment though).

 It's an original IBM CGA 5153. Not sure what you mean by 2K or 4K.

 Ummm, what decade are we talking about here? You're comparing a 1981 display to a post 2000 digital camera? Get real.

 Not sure if that's a reference to the Lisa, but the Mac did 512 x 342. The IBM MDA card displayed 720 x 348 on any compatible monochrome monitor, any color (paper white displays weren't commonly used with IBM stuph). And granted, no graphics until the Hercules card came out.

 True, but for $2500, the price of the original 128k Mac IIRC, you could get a PC or compatible with double the resolution, with 8 or 16 colors.
