[sebhc] h17 and h8d disk images

[Barry Watzman]

Unreal.  Steve Parker, Jim Tittsler, Barry Watzman.

It's like old times.

Now if we can find Gregg Chandler, Bill Zurney, Mike Hakeem, Ron Kasik,
Babu.  Oh, wait, this is the 8-bit group.  Better get "what's a Z-80" Neil
Beneditz and Tom Yeager; and I think that Jack Crenshaw is floating around
somewhere as well.

Who'd I leave out?

Yes, I mentioned it here a couple of months back.  It was
indeed 4200h.

What I can't remember for sure is if it would work with the
H8-5.  I'm pretty sure it did... but I think you'd have to
try it to find out.
