Ron,
One comment about parts count. As you are probably aware, CBM has it's
own chip manufacturer..MOS to be exact. I would suspect that before CBM
decided to integrate many chips into one thou….they'd like to make sure that
there would be a payoff (profit) in doing that. That means working out design
bugs fully, having experience in real-world usage (vs lab testing) and total
sales of the product.
I'm sure that at some time, the parts count will come down. I'd
suspect that for now…CBM used off the shelf chips for the most part in an
effort to lower startup costs. If the economies of volumn warrant it…I think
you'll see custom chips future versions of the board.
All that aside, having high parts count doesn't necessairly effect
performance. Moving lots of separate parts into one chip may not speed things
up at all…it'll only improve hardware reliability (less parts to break) and
lower production costs.
Yes, sometimes during the move from multiple parts to a single chip can
speed things up due to design changes or improvements made during the move.
