Which EEPROM? How is it being accessed hardware-wise? I've got a small program somewhere around plus circuit scheme on how to read/write ``industry-standard'' serial EEPROMs (93C46, 93C56) via the printer port. It requires either a voltage transverter from 3 Vdc (TTL high level) to 5 Vdc or an external +5 V source, and some 74LS00 or similar acting as a line driver. -- J"org Wunsch Unix support engineer joerg_wunsch@interface-business.de http://www.interface-business.de/~j
