Good luck! Meanwhile, I'll try to get that blown

Best method for replacing chips is to cut the pins of the
broken
part and then take out the single pins with a desoldering pump.
Works good even on multilayers with a good soldering iron.
I suspect replacing the 74123 with a 74LS123 will
change the timing? -
Depends on the purpose of the gate. If it is not used to
generate
timing it should be no problem to replace it with a LS type. (IMHO)
