coz they melt after being used for a drive test of 8 hours ....
brings back find memories... nashville tennessee... sprint pcs as the customer. Drive test in a minivan... 4 cell phones strapped to the back of the headrest and wired to the laptop (rubberbands holding phones)... laptop, gps receiver with external antenna on roof attached both together to the laptop. Basically scooting around drive testing the network for an update...
....and yes, multi plug adaptors FRY, MELT and SMOKE (even the good ones) when you hook mad things up to them like we did. From then on we only rented minivans with MULTIPLE 12V plugs we could wire from.
Ah the good ole nortel days when the stock was 85 (now 3.85 ).
