The car won't stall and the worse that would happen is that 
your alternator if in good shape would cause a voltage spike to 
go through your system, which rarely occurs.  I to have the 
degree in electronics and am currently a tech with Baxter 
International.  Almost all electronic IC's that were/are 
manufactured after '80' are protected from such voltage spikes 
even static discharges of over 32,000 volts, and most 
electronic designs take this into consideration including your 
autos comp.  Either way though the negative cable removal 
was only suggested to keep someone from doing a spot weld 
job on there car but removal of the positive cable would avoid 
the above voltage peak if it were to occur.
