Emax

I am still having intermittent failures with my SCSI setup and have a general question about termination.  At this point I am convinced that the ZILOG chip just was not advanced enough in it's day to be compatible with devices that SAY they are backwards compatible.  The data sheet says the chip does 3mb where we all know SCSI-1 should have been 5mb.  If a major standard like that was compromised, I can't imagine what other shortcuts they took.

If the EMAX II models that originally were HD models had an internal drive mounted by the factory AND still had the external SCSI port, how exactly did they get around proper termination?  Did they come with a 25 pin terminator that acted like a cap to the port that you had to keep track of as an accessory?

I am considering installing a mini toggle SPST switch that sticks through one of the slots in the back to turn on TRMPWR on the ACARD adapter to terminate the ZIP drive I am trying to install for when I want to connect an external device as well.

Any help or suggestions?
