I have cleaned the edge connnector again using IPA just in case but it turns out my 16k memopak works fine.Moggy wrote:Could be a dirty edge connector or the xpand not fully seated.
I say this because the first spand I bought I fitted into a Memotech case which had the Velcro that Memotech supplied fitted to the pack and the rear of the zeddy. This meant that the spand stood off from the case slightly and during boot up I got speckles and artefacts.
Removal of the Velcro meant the spand pushed fully home and problem solved.
I think it is seated fully - it won't go in any further.
I have also removed it from the memopak case as I have just got the ay board fitted.
