#105126 - card design enclosed
Responding to: ???'s previous message

can we see it too...? :)

Valentin



Please use this link to see the card design.

http://www.8052.com/users/Suresh/card%20ckt.pdf

my doubts are;

1)How the base address of the card is set using the DIP switch arrangement shown in the design. I just want to know the logic behind it. i.e., how the base address could be set, by switching the DIP switch 'ON' or 'OFF' .

2)what is the initial state of the address lines and data lines(high or low) in the ISA slot.

your relplies could be very helpful to me
