Hi Josh, yep the ribbon cable may be the culprit.
They have the wires very close and in precise
parallel so capacitance may be too high with 18"
of cable.

Get a knife and split between the wires, so you have
5 strands, then spread them apart and try that.

I do ICSP with the Picstart+, which is less critical
as i think it's a bit slower baudrate than some other
setups.
I still use 5 loose wires, bunched with 2 cable ties
so they "splay" and no wires are close for any real
length of wire. :o)
