... ... Mine is pretty close to that. I converted the data you gave to a binary file (8K, based at 0x20040000), and after a few moments with the disassembler, here's what I get. (The .space pseudo-directives are space that exists in my 8K file but which you didn't give values for. The end of the disassembly is three .bytes because it's only part of an instruction.) Note the syntax is more Unix than DEC. If you prefer the DEC way, change $ into # and * into @, and probably throw in a few other tweaks I've forgotten. (It's been a very long time since I used MACRO-11.) # coresize = 0x2000 # corebase = 0x20040000 20040000: .space 68 20040044: .ptr 0x200418ad 20040048: .ptr 0x2004c359 2004004c: .ptr 0x20041881 20040050: .ptr 0x2004539c 20040054: .ptr 0x20041887 20040058: .ptr 0x2004e4a0 2004005c: .ptr 0x20041890 20040060: .ascii "****************************************" 20040088: .ascii "************************" 200400a0: .space 6157 200418ad: entry mask: r5 r4 r3 r2 200418af: pushl $000000ef 200418b5: calls $1,0x20045120 200418ba: movab 0x200418c8,r2 200418bf: clrl r0 200418c1: movzbl *$2004000c,r1 200418c8: cmpb r0,r1 200418cb: beql 0x200418d0 200418cd: brw 0x200419fe 200418d0: movab 0x200418df,r2 200418d5: movzbl $1,r0 200418d8: movzbl *$2004000d,r1 200418df: cmpb r0,r1 200418e2: beql 0x200418e7 200418e4: brw 0x200419fe 200418e7: movab 0x200418f6,r2 200418ec: movzbl $2,r0 200418ef: movzbl *$2004000e,r1 200418f6: cmpb r0,r1 200418f9: beql 0x200418fe 200418fb: brw 0x200419fe 200418fe: movab 0x2004190d,r2 20041903: movzbl $3,r0 20041906: .byte 9a 20041907: .byte 9f 20041908: .byte 0f 20041909: .space 1783 /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
