Oh yes, I forgot about the 8-bit latches. They are very useful in the old days.

How nice if they are in M$ instead of US$. Then I would have order half a dozen to play with.
the 8*8 matrix matrix looks better in lower case and is not that hard to interface.
I have bought this from eBay:

Or use 2x 74HC595 serial to parallel shift registers and bit bang the patterns into the SR using SPI interface. This would required only clock, data, /OE and /RESET from the PIC. For each additional digit just add 2 more '595
Simple enough eh! Multiplexing not needed.
