DEC LN01 used an 8086 and 8089 for the RIP (raster image processor).
The 8089 did the parallel IO to the host (Dataproducts interface)
and the band buffer to video serializer (7+ Mbits/sec). The band buffer
depending on mode was either a 16bit wide scanline segement of binary
data or the 8089 would use the band as raw data and translate it for
font lay down. Both chips were working hard at 12ppm.
