Adram 540 problem

[David Wright]

So I pull out an old rev 5 Amiga 500 to test.
Everything seems to work good, shows only 512k chipram and no other.

I forgot there is the Adram 540 installed but doesn't show the ram. I take it all apart and it has a cable running from the adram to the Gary socket. I checked all the connections, tried to reseat chips but still no ram showing.

Is there any way to tell if the board is any good other than obviously trying to use it in trap door?

I am just assuming this was configured correctly from the original owner. I did run the disk memory checking routine, it saw nothing but the original onboard ram.

I do know about the auto config but some ram would still show.

I will take apart again and look further.

Thinking the connector in the trap door may be an issue.
