If you have problems finding specific parts, try searching on Mouser, Digikey, or Jameco.
Look kere for a Digikey parts list.
Here's some info on using an LM311 in place of the CA3140E.
Since Digikey no longer stocks the ICL7660 inverter, your next best bet is to get them from Mouser. The Mouser part numbers that will work are:
o 570-ICL7660CPA (Direct Replacement)
o 513-NJU7660D (Generic Replacement)
Mouser also stocks the CA3140, their part number is 570-CA3140AE.
