Unknown 8085 opcodes

Hi folks, Any 8085 assembler geeks in the house? Official Intel docs don't seem to be helping with this one, I have 8085 and D8741A peripheral controller dumps both containing several opcodes that two disassemblers aren't recognising and any docs I've been looking through for either 8085 instructions or the UPI instruction set don't seem to feature them either. The codes are 0x08, 0x10, 0x18, 0x28, 0x38,0xD9, 0xDD and 0xED. 0x08 nearly always follows a 0x01 LXI B instruction, the others don't seem to have an obvious pattern. I've pondered if 0x10 is INC @R0 because the binary for that is 0001 000x where x is either 0 or 1. By the same reasoning 0xD9 could be XRL A,R1 (opcode 11011xxx) and 0xDD could be XRL A,R5 but can't match the others. Also the surrounding code doesn't mention those registers. Example 8085 code fragment: 3440 1792 09 DAD B 3441 1793 01 01 08 LXI B,0801H 3442 1796 08 UNRECOGNIZED 3443 1797 12 STAX D 3444 1798 0D DCR C 3445 1799 54 MOV D,H 3446 179A 65 MOV H,L 3447 179B 6C MOV L,H 3448 179C 65 MOV H,L 3449 179D 70 MOV M,B 3450 179E 68 MOV L,B 3451 179F 6F MOV L,A 3452 17A0 6E MOV L,M 3453 17A1 65 MOV H,L 3454 17A2 20 RIM 3455 17A3 44 MOV B,H 3456 17A4 65 MOV H,L 3457 17A5 74 MOV M,H 3458 17A6 61 MOV H,C 3459 17A7 69 MOV L,C 3460 17A8 6C MOV L,H 3461 17A9 73 MOV M,E 3462 17AA 01 04 05 LXI B,0504H 3463 17AD 08 UNRECOGNIZED 3464 17AE 17 RAL 3465 17AF 53 MOV D,E 3466 17B0 65 MOV H,L 3467 17B1 6C MOV L,H 3468 17B2 65 MOV H,L 3469 17B3 63 MOV H,E 3470 17B4 74 MOV M,H 3471 17B5 20 RIM
