8x8 LED Board Driver

Hi Paul
I want to thank you for allowing me to join your forum. The content and mode of discussion seems very positive and constructive.
You mentioned that you had found a pin for pin replacement for the STP16C596 chips used in your 8x8 LED Display Board. Can you tell me what that new chip is? I have also noticed that the 596 chips are fast becoming extinct. Another question that I have based on the constant references to memory limitations of the various RAM and EEPROM portions of the microcontrollers like 14k flash, 1k RAM, and 512 bits EEPROM for the Atmega 168 chip - Is it possible to add any sort of external memory chips or possibly double or triple-up on the microcontrollers themselves to extend the memory? This is probably a really dumb question but I had to ask.
Thanks.
