I did a lot of hardware debugging before recognizing that all of my available 72-pin SIMMs were not compatible to the KISS68030 board, so I decided to collect information about which ICs work and which do not.

If you have a KISS68030 with another brand of memory not listed, I would like to hear from you (same if you know about other memories that are not working).
