I also found that it stayed up marginally longer (ie about 2 seconds
longer in my case) but I think this is probably co-incidence.

On commenting out the line setting the 0x280a memory location, and
leaving the line setting the 0x80a memory location, it failed
immediately; but these difference may just be random effects.
