If someone is willing to send me their original chip, I will gladly read it and make the hex code file available to those in need who have access to a programmer (aka eprom burner).  For those who don't, I will burn a new chip for the cost of the chip and usps charges, which is approx. $10-12 for the blank chip, and $5 for usps priority mail. Those not in a rush can have it sent 1st class mail for around $2 or so.
