Guys:

I do not remember all the specs of the PCI bus right now (though I designed
one and it did work the first time; and it was way longer than the spec
allowed :-) well, I did not have much choice.
But: there is a book; I already wrote here about it at some point, "PCI bus
system architecture" (or close); by "Mindshare corporation". The new edition
with new specs is sold on "Amazon".
Plus the official specs that you can buy for $20.00.

It has it all.

 Hi! Can you mentions how many devices are on this PCI bus and whether this
PCI is being implemented for motherboard or using chips with PCI compliant
interface on a single board?

Subject: [SI-LIST] : PCI length calculations

Hello All,

I have a question regarding PCI length calculations for a 32 bit 33 MHz
PCI
Bus.
How do you arrive at the maximum length for a PCI 33 MHz bus?
I have done some calculations to arrive at the routed length required.
But the length is much lesser than the PCI length specified for 33MHz(
which
assumes say 12 inches as maximum)
Can anyone explain how to arrive at PCI lengths

Looking forward to your replies and suggestions

Regards
Suchitha
?
