Transitional Technology SCSI controller

I have an S-Box Q-bus SCSI controller made by Transitional Technology, 
it is missing two socketed chips; the PROM and what I think is a static 
RAM chip, both 28 pins.  Does anyone have the HEX file of the PROM?  
Does anyone know what the RAM chip is?  I curious to take a shot and see 
if this thing works.

The board doesn't have jumpers, is it hardwired to some CSR? Thanks.
