Not sure how I can get the value of my-self at the time of the exception?

Well, for a first pass, let's take a look at them before the FCode runs. After the above line, say

my-self .
my-parent .
my-space .

my-self and my-parent should be similar pointers into the forth dictionary, where the framework has allocated data for the instances of the video card node and the pci node (respectively).

my-space should be the high-order bits of the PCI address space, probably 0x1000 since this is device 2.
