Amiga 3000T Zip/Simm adapter

[amiga1260]

I friend of my bought an Amiga 3000T Zip/Simm adapter made by DJBase.

He tries every single SIMM modules and combinations, but he only see the half of his memory. Does someone know a SIMM modules that works well on this adapter.

He also has tried to set the jumper, but doesn't work.

The A3000T has  a 030/25 MHz and a Buster 9.

I have one of these, and I can use the full 16 MB. As statet in the manual you have to use two double sided 8 MB modules. I have a spare set of modules if needed, but any double sided 8 MB modules should work. Maybe it's a problem with the connection, or one of the memory slots?
