At the very least, I believe that you can boot from disk by starting at
location 040000.

I used to wander up to the local Heathkit store every weekend to play with
the H8, H11a (LSI-11 based machine running a variant of RT-11), and the
H89 - essentially a Z80 processor board and a 5.25" disk drive built into
an H19 terminal - I'd actually really love to have one of those, if anyone
has one they don't want ... :-)

Anyway, I was such a frequent visitor to that store that the manager gave
me a couple of advertising posters for the machines - one was a poster
that said "H8 POWER", above an illustration of the bootstrap address, as
it would appear on the H8 display in red 7-segment LEDs; I'm almost
positive that the display read "040000 Pc" .... The poster is still
hanging on my old bedroom wall at my mother's house, unfortunately I can't
get to it to look just at the moment ....
