For the purposes of comparison, I am attaching the uuencoded file devdir.zip, which in turn contains 4 file: devdir.org is the original assembly program devdir.dsm is the output of sourcer, without a hint file devdir.asm is the output of sourcer, with a hint file devdir.def is the hint file. Disassembly is an iterative process. As you gather more and more information about the target, you add that information to the hint file and then disassemble again. Sourcer has limitations, as does any disassembler on machines with multi-unit (in this case, byte) instructions. The pure disassembly is reasonably readable, but there is no guarantee that assembling the disassembled file will result in an identical file, or even in one that works! I have only seen this latter happen when disassembling code from an optimizing compiler. Usually, minor patching of the hints file, or changing some of the options will clear this up. You'll need pkupzip 1.02+. If this is a problem, please contact me via e-mail. kdq begin 664 devdir.zip M4$L#!`H````&`/6$9122:JLI1`(``)T$```*````1$561$E2+D1%1@T"`1(C M%!4V-VB)FML\!082$T3%]I;W@[H-RS;OW+1S09IE&_8LR)X@DS94./0MV;(@ MY]+-R[;,\X]]VR9Z&WTKMVU8.LT?=D[S'WTSO)&6#4.^Y40_T;)VTXY!WV33 MRBT[EH[YSJ.]D[J%6V=]FTWCO[1U&V&)5R>7]6TG_%TP<Z9AQ99E8_U,R]*E M(^QSRYXIWV[@MTF0;\V:8=YTP#>4<G6\YX1_C>4MM0R^EKMF^<OB*==PRC<9 MHSLL2#MR=QUL+4>[B>^Z4+P?)TR<.)0WENEMAOF0;7D%;[=OW98Y'L'5N8?5 M"3,FS"):-XOP308Z'9,FB*8;)(BP'V,ZB8,\O,P8T&%OU.<RIM,SIM,SIM,T MIA/4R1K4B7ED32/4.8WIM$T9TWF-Z?1-&-.YC>FD#2-U73'4&TT5S3I9Q+J& M*Z?]JE-JKJ7@<;0%FW,&=%@BT.&#WH`./R2\G@.=)F*VTN<WJM-%JN-Q5">- MG(W/89TV>J,JCB?R/<8ZEPFSAG4MQG4[#'4*Z**NT#]MFNJTC"THZG9&JGK7 M,-Q9?]NY9_Q$I6\:U*GTI$TQU*D^TC)QI)=HR:2)EAETR'2=UJV9Z621Z9MR MA7;7N&[J2*$SL".Y(X7BP(XDCQ1*!#L2Z&F90V5@ES>P6^DI[)T#N[2!W51/ M86\CV)&T2,LD6@.[Q('=NDAAK_B?@SV"FE@++LFPZ2#=UF5K=JP8ZTC"?,;G MF*_']DZP/JY),:/:;M?.F8[+W"+F;&Y/M>LB2=)%GS9)E`902P,$"@````8` M$)QF%-&`_43.!0``P!0```H```!$159$25(N05--#0(!$B,4%38W:(F:VSP% M!A(31,7VEO=!@FRH$&K0HT6.=\V<+&/.E-&\HN?.GCV"HP>8><($P=6V"BZN M$]$YT:)6B2:50AXL_N`QUT/EE@U+MRQ9'<HODV9+I6'=MLP)PSW(5LO*G9OV MK5L=TD`,->S<N67G1`LJEW@>U&U8MGGR]UR03^'2^;_C->P@D29=XC9@7`<# M36B"/,;PX+O/?@V#KHR_;5FW=!.*S?/E!@FWKEBV:<=L+^O%U>M<[X1CP*KS MSA(DF>0"&$&^W\H]FS`F3)AHGFNR9>V232NG>L.5^W9L0K-AY9B3=)(W71WM ML^U;.]8:+PMIQ9Q):Q;/BSDOPQP;%BW+&=;*R-\)\B3,$]4SC=B7&4.Z)OIT M*L@I86P[:1?]$E?KNZ?9NF['O"E!SE@Z@*3,-\BS9>FL=SM-T"#=1-5BE#<( M<WIL6SCFFBU+&<M3;9BTJN_'L.]*RC=<D&G-F&\Q2%>42ZP&,>>]+?CNMV;- MSJGVMG//X%?$/A?-^(I>_F\C>I(5FS`'T>$LZJ+'XMD*$:91--.@=-ULS8X5 MLQ9@$!-KR;=PB-`@S:9E6R:-;72H4)!`WIADYEG7=58(K_.N15F_!?E#;]<C M5\J0"UE/][$%?@RV@"E3!Y7X&"I1X'+&E*"$XV+"]9UF389VFZX<OI+MW)4P MB5R9<ORXP[REBD:F433\C**),G4,^-(-%WQ&THANWP#KLG'K6+F:QL>T6>0?
