If I recall correctly the book also describes tha basics of coding
your own fast drive access routines (fast loader, etc.) which is mighty
handy.

Somewhat Classic Computer related was my acquisition of a Color
QuickCam for my Mac, I know it isn't even near 10 years old but it is
worthy to mention for its almost instant imaging capabilities... The
thing has a range of 1" to infinity (you can zoom in on the numbers
printed on tops of chips and have them readable!) So now I have to
clear the piles of papers away from a corner so I can use the cam to do
shots of some of my equipment (like a better picture of the P-500, etc.)
To give you an idea of the detail I am extolling, check out this pic I
put on-line for you to see for yourself:

The pictue is of a 12/24 edge connector (.156" spacing), a Commodore
monitor connector and the top of a 6510 microprocessor DIP chip. (best I
could do in a couple minutes of scrounging.
Note this is 'medium size' and the resolution can go up to 640x400.
The real bummer to it is I don't think I can get it to work on my
Commodores,also it's leash (interface cable) is 6'long... :/
