Ah thanks. Hmmm been a while since I've heard the term octal. Isn't that also called base8, or 3 bit binary digits?

Just wondering what is the 74HT244? Is this some kind of counter circuit? I'm asking because my local Radio Shack didn't have it.

Ever see the mainboard for Atari 5200? If you put 2 regular notebooks side by side, it's almost that size. About 18" by 24" :-P To get this back on topic, anyone thinking of making a portable DC? I have considered it but it's on the back burner because I'd need to find a way to keep those ...
