Yeah...me too. The way the 2600 is set up, you'll get a total of 31 possible
values, assuming that the transistors are well matched. This is one value
short of 5 bits. Note that these values aren't quite linear. I forget which
way the curve goes, but I do remember seeing it on my o'scope a couple of
years ago...
Glenn,
Every once in a while you mention the DPC chip in Pitfall II. Did you ever
manage to snag docs for that beastie? If so, or if someone is willing to
document *in detail* the way it works (Bradford??) I'd like to try my hand
at recreating it. First in discrete logic, but finally in VLSI...a direct
implementation in silicon. I don't know that it would be useful, but it
might be fun to try.
Also, does anyone know of a source for this chip? Who made it? Who sells it?
What's the official part number? Etc...
-Chris
