RCA 1802
→Graphics: I think 256x216 with 8 fully independent colours qualifies as more than just "somewhat" higher resolution than a typical 64x32 in monochrome or with heavily attribute clashed 8-fore/4-background colours... like, just in terms of pixel resolution, it's *twenty-seven* times better. Specwise and in screengrabs it's reminiscent of the ZX Spectrum or early MSX, just with a few extra lines of vertical rez and no clashing.

RCA 1802
→External links: The "original 1802" datasheet is anything but, showing the specs of a later subfamily with 21+ years of further development, bearing different code suffixes; the "current 1802A" one is also mislabelled, as it is neither current (at time of writing, it's 11 years old), nor is it for the 1802A. Sort it out, people.

RCA 1802
→References: I can never remember if it's Noteslist or Notelist, and the preview doesn't show it properly in either case, so... eyes shut and click the button

RCA CDP1861
→Specifications: This is rather more the truth of the situation. The Pixie was cheap because it was actually an extremely simple device; a dozen or so vanilla gates and the bare minimum of something that could essentially pass for ROM with an integrated timer-cum-program-counter.

RCA CDP1861
→Specifications: It's about as rudimentary a color generator as the pixie is a pixel generator. Eight foreground colours limited in assignation to each 8x1 strip of (logical) pixels, and four mostly-different (only black is shared) background colours with half the horizontal resolution (...ie, no more than 4x32 blocks on a typical 64x32 pixel screen)...

COSMAC VIP
Whew. Bit of a chunky edit, so strap in. First up: Standard NTSC color frequency is NOT 3.52...whatever...MHz that was written here. It's 315MHz divided by 88, ie 3.58...etc, as can be easily discovered with five seconds searching this very encyclopaedia. Ditto the COSMAC clock - there's enough sources in WP itself pointing to it, eg. link to Pixie spec sheets that recommend a 1.76064M clock (with H/V freqs), though a curious 1.764M and a "halved NTSC" were also *acceptable*. So on and so forth.
