picture xm5ylx.jpg shows Revision 2 board which needs many jumpers 
and traces cut for SCSI to be used. If not skilled with a solder 
iron, should have a technician do the work or emax can be destroyed.

Same picture shows IC 49 with IP344, this would need to be IP356, 
which is hard to get- must be gotten from a dead emax in most cases. 
Binary is not available to make a new one....
IC13 is showing in ix813q.jpg. It is IP349- this would need to be 
IP355, which is also hard to get. Same problem from above- binary not 
available to make a IP355 chip.

Blank slot in m90ztq.jpg is where SCSI 5380 chip goes, but two chips 
above must be correct or just adding this chip is no good.

See Emax SCSI retrofit guide at emulator archive.

So in a nutshell-

a) You do not have IP355 and IP356 so, no SCSI.
b) Your board would have to be modified if you are able to acquire 
IP355 and IP356. Technically skilled persons only should attempt the 
modification.
c) You would also need to get SCSI 5380 chip

Regards,
Ted
