The overall firmware is 32KB in size.

So - you either load this as four 8KB EPROM images, or two 16KB EPROM
images (depending on whether you're using 2764 or 27128 EPROM devices.)

The .zip file has the images provided for either case (e.g., 4 images if
using four 8KB EPROMs, or 2 images if using two 16KB EPROMs)

This is the main/full firmware for the polaris (i.e., this is the
processor firmware).
