Hi, a question: how do you power your 24C02 EEPROM? Did you implement the required pull-ups? Remark, that some parallel ports give only about 3V when high, and maybe 0,8V (ughh!!) when going low... Check the levels! I hope this helps. Imre On Fri, 23 Jul 1999, Simon Redwood wrote: > I am trying to read information from a 24C02 eeprom through the parallel > port using C.
