Failed upper ROM with Dandinator Mini CPC on a 6128

[andymccall]

Hi,

I'm restoring an Amstrad CPC 6128 and after swapping the memory everything seems to be working however when I run the Amstrad Diagnostics v1.2L that's included with the Dandinator Mini CPC I'm getting a failed upper ROM test.

I don't think it has failed as everything seems to be working great.

Does anyone know why I'd get this failure?

Thanks,

Andy

Maybe you haven't validated all BASIC 1.1 commands. 
You should check the contents of the BASIC ROM and compare it with that in the emulators.
