  The games were developed on the NeXT but a lot of things were missing. Like, key bindings. And the mouse. And sound. Also, there was no dithering on grayscale machines, and most of them _were_ grayscale back then. Also, he was just blatting bitmaps to the screen from a simulated VGA buffer he had, so it was quite slow (blatting bitmaps was NOT fast with Display Postscript). We ended up hooking into something called "Interceptor" which was a very early version of direct VMA (and which he'd done experiments with, and turned us on to). But, make no mistake, Carmack did ALL the heavy lifting here. I in no way want to take credit for Doom or Quake. I just hooked the plumbing up so we NeXTers (and later OS Xers) could enjoy the amazing games he wrote.
