Complete the nanocode for HQ that emulates at least CGA 80x25 text mode.
Basically done, as of SVN revision 693.
Understand what process has to be performed and write the code to do it. Note that HQ is single-threaded, so in the middle of doing translations, it needs to have explicit subroutine calls sprinkled about that will look at request fifos from PCI and process them. I've also described this in detail before.
