Yes, this can be done with a PIC. You can start with a PIC16F84 which is EEPROM. > Question is what do I really need to buy?? most of what I do is > strictly R&D/one of a kind stuff.

Any help would be greatly > appreciated and I promise no more Books to the list. NONE at all. The development software MPLAB is free. You can download it at the Microchip website (http://www.microchip.com). It includes a simulator and an assembler. You must learn the assembly language (only 30+ instructions). For the programmer, you can DIY it (do it yourself). Check http://www.gbar.dtu.dk/~c888600/newpic3.htm for the diagram and the software. This is a serial port programmer and requires no external power to operate (power is taken from RS232). regards, Reggie
