I did do a small amount of web surfing and learned a little bit but was not successful in finding any "mother lode" of information. Thanks a bunch to those who responded. I did learn that the chips are manufactured by Symbios Logic (SL) under contract to NCR. The SL WWW pages have a fair amount of high-quality information, specifications not just marketing info. AMD also has a line of chips that it manufactures that they claim are compatible. The SL chip varieties are as follows: 53c810 - FAST SCSI-2, no BIOS 53c815 - FAST SCSI-2, BIOS 53c820 - FAST WIDE SCSI-2, no BIOS 53c825 - FAST WIDE SCSI-2, BIOS 53C860 - Fast-20 version of 810 53C875 - Fast-20 version of 815 SL claims that the 860 and 875 are backwards compatible to the 810 and 815. This may or may not translate to being usable with FreeBSD, caveat emptor. Here are the host adaptors I was able to find. I suspect there are many more. If anybody knows of additional adaptors or can fill in the blanks below, I'd appreciate hearing about it by e-mail.
