Does anybody know of a way to combine a PIC with a really large chunk of serial memory, much more than 8 kilobytes? Do you know what serial memory chips are available, and practical? EEPROM or FLASH would do, it's got to be non-volatile memory. Arvi Karhumaki EMail: arvi@vistacom.fi Support Technician Phone: +358-9-6226 2325 Vista Communication Instruments
