It's EEPROM without the ability to erase each byte individually. There are no differences in the two chips' instruction sets, and the F84 is completely compatible with code written for the C84. Code that uses the F84's extra RAM, of course, won't work on the C84. > and just for a conversation topic... Digi key is great aren't they? Well... They're ok, but their minimum order amount ($25, I think) can sometimes be an obstacle. Mouser (800 346-6873, or http://www.mouser.com ) has just as large a selection and no minimum order amount. -Andy === Andrew Warren - fastfwd@ix.netcom.com === Fast Forward Engineering - Vista, California === http://www.geocities.com/SiliconValley/2499
