Sun 3/110 memory issue

Howdy, I finally got down to FL for long planned rescue of some Sun VME stuff... (BTW, I'll be posting some VME boards available in the next day or so, FYI...) and in the rescue I got a Sun 3/110 CPU board (Hurrah!... what I've been looking for a long time ) and even a 4/110 CPU board which I think I'll build out too. However, I've got a memory issue with the 3/110... I get the following output on the console with diag enabled: PROM Checksum Test DVMA Reg Test Context Reg Test Segment Map Wr/Rd Test Segment Map Address Test Page Map Test Memory Path Data Test Err 2: Addr 0x00000400, Exp 0x00000001, Obs 0x00010001, Xor 0x00010000 Can anybody tell me how to determine what bank this is on the 3/110 board, so I can replace the chip? They all look socketed and I've got a drawer full of RAM that I can swap out, if I can figure out the chip... BTW, when I jumper J3100 it cycles in both diag and normal, even with another memory board in... does anybody know if the 3/110 would boot with it's on-board memory disabled? Thanks.
