Help installing SunOS?

So, I'm back to trying to get my 3/180 running again. I'm trying to boot a SunOS 4.1.1 "for Sun3" install tape that I produced from images and directions that on the sun3zoo site. When I try to boot, it seems to read from the tape OK, but then it bus errors: Boot: xt(0,0,0) Size: 507912+123920+79144 bytes Invalid Page Bus Error: Vaddr: 0E0894E4, Paddr: 000014E4, Type 0, Read, FC 5, Size 4 at 0x0000400A. The CPU is a 3/180 with 16MB of ram, an Xylogics pertec tape controller w/ Sun badged Fujitsu M24444 tape attached, and Xylogics SMD disk controller with a Fujitsu Eagle I think (aka Sun 595-1309). Anyone have any ideas what I might be doing wrong, or perhaps a working installer on 9-track tape they could copy for me?
