Based on a photo comparison, I believe I am the new owner of the DPT SCSI board, which is in my 50MHz build. I also possess the same (but different) model Adaptec card for floppy controller. Did you ever get to a point where you were able to run any meaningful benchmarks? I'm finding that the two boards are very similar in linear transfers (~9MB/s), but the cache makes a huge difference in access times for random transfers. The DPT board is a serious piece of kit. With the DM4000 array add-on board I can only guess it will do RAID with the correct configuration utility. I have not tried this yet, but would be fascinated to see the performance of interleaved drives.
