This expansion unit for the Video Genie provided a high-resolution monochrome graphics overlay of 384x192 pixels. The high-res layer xor'ed with the text layer and overlapped it exactly - each text character mapped to a 6x12 block of pixels. The software interface was via four I/O ports and was therefore not particularly fast.
