A Question about SIMMS for IRIS 4D/25

[Thilaka Sumanaweera]

We have a Personal IRIS 4D/20 (16Mb) and we are going to upgrade it to
4D/25(32Mb). We would like to get 16Mb of additional memory for this.
Will the 30-pin SIMMs which fit in the 4D/20 be compatible with the
4D/25? If not, which pin configuration/reference no. should we use
when ordering?

Thanks in advance,
