Why no portables? or are you just focusing on consoles?

Would Neo Geo CDZ count or no?

Goldstar 3DO to be added as well

Sega Mega Jet (Portable Sega MegaDrive)

Sega CDX

JVC X-Eye

Sega Nomad <-- not just a portable, but a full blown Genesis as well

And the Texas Instructment 99/TI-99

also, MSX and Sharp X68000

Turbo Express <--- portable NEC that played HuCards as well
