Heath h-8

Ok guys, another project (yes, I really do have this many)... :) I have a Heath H-8. Seems to work. Thanks to the help of a guy who runs the only H-8 dedicated web-site I can find, I now believe that the thing has an "H-17" hard-sectored floppy interface, as well as a 4 port serial interface. Now, keying in programs from the front-panel is cool and everything, but I'm thinking of putting a console on it, and a disk drive, so that I can run HDOS, and maybe have some external storage. ;) So, how rare are the peripherals? In the absence of a heath floppy drive, what else might I use(and how...)? Anyone know where I can get one? I have a Lier-Siegler ADM-5 terminal, which I may want to plug into it (It's the closest thing to authentic I've got... :), but on the other hand, again, how rare are the Heath terminals? Assuming I ever get all of these things, the last question would be: Would anybody be willing to make a copy of HDOS? Otherwise is there a possibility I can download it from somewhere and actually get it on a disk properly? Another interesting question is this: My H-8 has a strange wire-wrapped breadboard, on top of what appears to be a normal 8080 CPU card. The breadboard contains a Z80 cpu, and plugs into the CPU socket of the 8080 CPU card. Any guesses about this? Might this mean I can run CP/M with some toying around? (Did CP/M ever run on these?)
