If you have already built the EEP-0.1 burner, you can make the following
modifications to make the EEP-0.2 burner:

- remove the connection from 74HCT157 pin 1 (SEL) to the upper
  74HCT259 pin 11 (Y6)
- remove the 1K resistor that is connected from pin 1 of ZIF-socket to Vcc
- add a new connection from pin 1 (SEL) of the 74HCT157 to pin 9 of
  of the DB-25 parallel port
- add a new connection from pin 10 of the upper 74HCT259 to the unused
  pin of J1
- add a 180 ohms resistor from pin 11 of the upper 74HCT259 to
  pin 1 of the ZIF-socket
