Open firmware trouble on StarMax 3000/180

Hello-

This is my first time on this list so if I'm in the wrong 
place for these questions just let me know and I'll kindly 
leave.

I am "trying" to turn up netBSD on my StarMax 3000/180.

I tried to follow the Getting to the Open Firmware Prompt 
(Harder method using MacOS)

Basically I used Bootvars under macOS.

I unchecked the AutoBoot and checked All variables

Then I put kbd in for the input-device and for the output 
device I put /ATY,264VT@11

I clicked Write and then rebooted.  Now I get no video 
sync.  I assume Open firmware comes up right away?

I see something about swaping ide cables, but shouldn't I 
at least get a prompt?

since I took ttya off out of the bootvars its probably not 
coming out of the serial port is it. ????

Any suggestions?  Have I fatally messed up my machine?

Thanks in advance

Ben Wehrspann
