Hi folks.

I grew up with an Apple //e clone that I used from 1985 to 1994! Unfortunatelly I got rid of it back then. As I am getting old and nostalgia is hitting hard, I decided to rebuild my childhood system.

I got the very same clone and I am now adding everything I had on my old one. I got a 512k RAMWorks, which has been tested in 2 original //e and one identical //e clone to use in mine, it is working.

However my system won't even see the card! I have tested the continuity on all aux pins to the board and from the pins to the card. Everything seems OK.

My guess is that some IC, which controls the aux slot is faulty…

Anyone could point me to instructions on how to test that?

Any ideas of what can be wrong??

Thank you very much for any insight you guys can give me!
