Amiga 500 - 512k Ram Expansion problem
Hi,
I have this 512k RAM expansion board in the trapdoor that sometimes works, sometimes it makes the Amiga screen turn red, yellow, grey, etc. Are these memory expansions repairable? So far I've tested the tracks for continuity and they all seem fine. the board is an AMRAM-NC-Issue 2 with no battery. TIA |

Sometimes the connectors go loose in these, so they only work when you hold them in at an angle.

I see, I'll try moving the board a little. Thanks!

There might also be micro-cracks in the solder. Reheating the tin on every contact should fix it
