Do any of you know if chip programmers (the EMP-30 specifically) work okay

My *guess* is that you probably would not have much luck with a
parallel port which is behind any sort of USB interface. You might
have to read some fine print to determine whether the ports on a
notebook port expander / docking station are behind a USB interface or
a more native PCI bus.
If you try an ExpressCard (replacement for CardBus) parallel port card
you also need to make sure it is a native PCIe parallel port and not a
USB-parallel port. The ExpressCard form factor has both PCIe and USB
interfaces and it is not always clear which interface an ExpressCard
device uses.
I have a BP Micro programmer with an parallel port interface. I am
curious if it would work attached to a PCIe parallel port chip such as
the Oxford/PLX OXPCIe840
http://www.plxtech.com/products/uart/oxpcie840 That chip could be
used on either PCIe add-in cards or ExpressCard cards. If I can find
a cheap card using that chip I should give it a try.
