RE: Peculiarities in HP supplied S/SX and G/GX ROM dumps
For example, for the GX-R ROM dump on http://www.hpcalc.org, starting at address 0x0100h, in nibbles, at least the next 64 nibbles should be zero, but they're not. eg. :

Code:
$ xxd -c 1 -l 32 -s +128 ./gxrom-r.bin
00000080: e8  .
00000081: 00  .
00000082: f2  .
00000083: 6f  o
00000084: 40  @
00000085: 00  .
00000086: 69  i
00000087: 0c  .
00000088: 88  .
00000089: 33  3
0000008a: 00  .
0000008b: 3a  :
0000008c: 24  $
0000008d: 11  .
0000008e: 10  .
