Repackaging the SIMM ROM types in DIPs is no doubt achievable but you need a lot of motivation to try it. Trag knows about repackaging soldered ROMs as SIMMs from his work on the IIci SIMM for an SE/30.
The above is true for values of repackaging which are equal to desoldering the ROMs from a IIci, reading the code out to disk, and writing the code into different Flash chips which were then soldered onto Gamba's board.

I mention this because it was not a case of removing the ROM chips from the IIci board and then soldering the same chips to a SIMM. One might interpret repackaging that way.

As it turns out, the ROM downloading utility which one uses to get a ROM file for the various emulators delivers a ROM file which is identical to what I got from reading the actual ROM chips after removing them from the IIci.

So I could have saved some trouble, but we didn't know that for certain ahead of time.
