hp700rx machine

  (unnamed machine)  [hp700rx]
  \-- mainbus0
      |-- cpu0  (i960CA, 25 MHz)
      \-- ram0  (2 MB at offset 0x3fe00000)
The hp700rx machine template tries to emulate a HP 700/RX X-terminal, with an i960CA processor.

TODO:
Everything.

Note: this should hopefully/eventually work:

$ ./gxemul -V -e hp700rx C2708A 

but the entry point (according to Intel's b.out format) is 0x3fe05000, which is wrong. Clearly, the HP 700/RX deduces the entry point some other way. For now, one way to load the binary with correct entry point is to use the "raw" file loader and specify addresses explicitly:

$ ./gxemul -V -e hp700rx raw:0x3fe05000:0x2c:0x3fe05094:C2708A
