I am vary old 
and am trying to understand this technology. I am vary much a geek thou.
I have always been fascinated by the interface between two processors. So I built a serial cable and started looking around inside my seagate drive. (I used to do the same kind of thing on the vic20) The seagate 7200-12 only allows dumping of memory 1 block at a time. No big deal, I wrote a program that interfaces with realterm to keep downloading and saveing these blocks to a text file. I let it run all-night and accumulated quite a bit of data. Then this morning I used a hex editor to view the output. I was shocked to (not) see there were no ascii characters! Why not? What am I missing? I just figured it would display some of the hex as ascii data. I will gladly share the program I wrote for even a little information.
Thank You!
