Don't know if this will help at all. Not sure if the UC07 and UC17 share the same firmware and VAX host resident FRD code. On the QBus UC07 version (firmware version G143R) there is a short stub located at 80h which jumps to the main code at 280h. (If you have a VCB02 instead of a serial console you start at 82h which then jumps to 282h and does something slightly different). I dumped the memory for this code from the VAX and entered it into SIMH to use SIMH as an VAX unassembler and this is what it looks like. If the UC17 host resident VAX code is the same, any clues here as to what might be causing a halt on the 11/730? sim> e -m 80-87 80: BRB 85 82: BRW 282 85: BRW 280 sim> e -m 280-3d3 280: BRB 298 282: BISB2 #1,27F 286: MOVL #80000003,@#2008800C 291: MTPR #800,#4 298: MOVL #80000002,@#20088008 2A3: NOP 2A4: MTPR #1F,#12 2A7: MOVAL 400,R1 2AE: MOVL #200,R2 2B5: MOVL #0,(R1)+ 2B8: SOBGTR R2,2B5 2BB: MOVL #20001468,R5 2C2: CLRW (R5) 2C4: BITW #800,2(R5) 2CA: BEQL 2C4 2CC: MOVW #3003,2(R5) 2D2: CMPW #100,2(R5) 2D8: BNEQ 2D2 2DA: MOVW #4600,2(R5) 2E0: CMPW #400,2(R5) 2E6: BNEQ 2E0 2E8: MOVW #400,2(R5) 2EE: TSTB 27F 2F1: BEQL 30E 2F3: MOVL #1,R0 2F6: JSB @#20040008 2FC: CMPB #18,R0 2FF: BNEQ 304 301: BRW 362 304: EXTZV #0,#7,R0,R0 309: MOVL R0,R2 30C: BRB 338 30E: MFPR #20,R1 311: BBC #7,R1,362 315: MFPR #21,R2 318: EXTZV #0,#7,R2,R2 31D: CMPB R2,#13 320: BNEQ 338 322: MFPR #20,R0 325: BBC #7,R0,322 329: MFPR #21,R0 32C: EXTZV #0,#7,R0,R0 331: CMPB R0,#11 334: BNEQ 322 336: BRB 362 338: BISW2 #200,R2 33D: MOVW R2,2(R5) 341: MOVW 2(R5),R2 345: BITW #200,R2 34A: BEQL 341 34C: BICL2 #200,R2 353: MOVW R2,2(R5) 357: MOVW 2(R5),R2 35B: BITW #200,R2 360: BNEQ 357 362: MOVW 2(R5),R2 366: BITW #100,R2 36B: BEQL 2EE 36D: MOVW R2,2(R5) 371: MOVW 2(R5),R2 375: BITW #100,R2 37A: BNEQ 371 37C: BICW2 #100,R2 381: MOVW R2,2(R5) 385: EXTZV #0,#7,R2,R2 38A: BEQL 3C4 38C: TSTB 27F 390: BEQL 3B3 392: MOVB R2,3CF 399: MOVAL 3C7,R0 3A0: JSB @#2004000C 3A6: MOVW 2(R5),R2 3AA: BITW #100,R2 3AF: BEQL 3A6 3B1: BRB 36D 3B3: MFPR #22,R1 3B6: BBC #7,R1,3B3 3BA: MTPR R2,#23 3BD: MFPR #22,R1 3C0: BBC #7,R1,3BD 3C4: BRW 2EE
