NEO-ZMC2

and in one package.

Can address up to 4MiB of M1 ROM.

Found in second revision MVS boards (for the PRO-CT0 logic only), and AES cartridges.

NEO-ZMC part:
 * SDA0,SDA1,SDA8~SDA15: Z80 address bus
 * MA11~MA21: M ROM address outputs

PRO-CT0 part, inputs: Outputs:
 * 12M: 12MHz clock, outputs next pixel on falling edge.
 * C0~C31: C ROM data bus (2*16 bits). Gives all the pixel data needed for a 8 pixel line.
 * H: When high, reverse bit order of pixels shifted out (used for sprites horizontal flipping)
 * EVEN: Swap A/B pixels.
 * LOAD: Latch C ROM data on rising edge of 12M.
 * DOTA: High when pixel A is opaque (color > 0)
 * DOTB: High when pixel B is opaque (color > 0)
 * GAD0~GAD3: Pixel A color index
 * GBD0~GBD3: Pixel B color index
