* Modification Log:
* -----------------
* .01 joh 071092 added argument to calloc()
* .01 joh 071092 stripped the hkv2f specific portion off the comet
* .02 joh 071092 stripped the hkv2f specific portion off the comet
* std addr base specification and left it at base
* addr zero which is most likely wrong.
* .03 joh 071492 use extended (A32) address space
* instead of standard (A24) address space
* for the base address of the waveform memory
* (changed arg to sysBusToLocalAdrs()
* .04 joh 071592 fixed to use correct size when incrementing
* to the waveform memory of the second card
* .05 joh 071592 modified A16 & A32 base addr to match AT8
* address standard
*
