#98990 - the reason what you dont beleave...
Responding to: ???'s previous message
Dear Erik,


reasons



1. I live in a rural ARea where electronic componants are available available easily. i have to wait for them 15-30 days if got the vendor and if he agreed to supply in small quantity. during this the tempo gets lost. so i have to depend on the chips already in use and available here locally. for example this ADM1232 is used in Public call office call meter so that i can get them.

2. Board making is no easy task here no AIDS available, for example i was looking for press-n-peel papers and unable to get them before one friend of mine sent it from sydney. and they are traveling since 15 days and i'm unable to get them yet.

3. BY freeing ALE i want to use it for RAM powerdown and power switching.
