Those slots may not be for a CPU or EPROM. It may be some kind of expansion
for DRAM or something for cache, especially if it is a SCSI HBA. I remember
various cards over the years having empty slots on them where you could add
RAM/DRAM and other chips to boost the cache size or memory available (like
for a video card.)
Alternately, those slots could be for a CPU or EPROM that could turn that
SCSI card into some kind of hardware RAID card (highly unlikely given the
age of the card, though.)

This board seems to be in good shape, but unfortunately two square
sockets (for microprocessor I think)
Do you have a photo of the board? If it uses a fairly generic SCSI chipset
it might be possible to narrow it down from a photo of the board. Maybe a
chip collector "collected" it's CPU and/or EPROM(s)?
