decompilation as archiving?

Hand-disassembly is just the start. Vast machineries of automated disassembly/decompilation is used throughout the world in piracy and reverse-engineering activities. These sorts of tools have been in existence for at least 30 years, very likely 40 or 50 years. Related to these machinations are other tools used in reverse-engineering, including emulators, simulators, in-circuit emulators, logic analyzers, etc. All of these tools are also used in retro-computing as defined by many different groups: video gamers, emulation of historically important systems by academics, and everything in between. But what you describe goes way beyond simple archiving, and more into the tools that let you analyze and appreciate the code. If you can combine the code with the original designers, original users, original business documents, etc., then you are really on the road to a complete recreation of not only the code, but the world at the time. As a classic example, 25 years ago you could buy a tool that disassembled your CP/M binaries and turned them into *commented* sources. Not the original source, of course! Tim.

decompilation as archiving?

by legalize＠xmission.com

Has anyone considered decompilation (producing sources from binaries) as a way of archiving system or application software that is defunct? I know lots of people have disassembled ROM listings and created commented ASM listings from the ROM, but what about larger systems where hand-disassembly is impractical? -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Documentation

by dm561＠torfree.net

My recent post re BBM manuals has left me with a bit of a dilemma; I've got several more boxes of various manuals etc. to dispose of and I'm not sure what's the best way. On the one hand, it benefits everyone to have them in Al's hands, who has the means, time and willingness (thanks, Al) to make them available to us all. On the other hand, anyone who actually owns the relevant equipment would probably like to have original documentation. When I put them up on the list, I'm inevitably going to disappoint someone; should I just offer it privately to Al and rely on him, or? Comments? mike

you can do very well copying manuals and such with a mini digital cam, if its allowed.

Anybody have recent issues of Make? Somebody told me tonight that I'm quoted, two or three issues ago, but I have no idea what that's about .... So naturally I am feeling curious! Would appreciate if someone could look. Thanks! - Evan (Koblentz)

cloning CDs with errors?

by julesrichardsonuk＠yahoo.co.uk

Random thought of the day.... I've seen a few CDs around where the manufacturer has deliberately included errors on the disc to make piracy more difficult - which is a noble enough thing to do, but a bit of a pain in the butt when you want to make a legitimate backup copy of a disc :-( Has anyone come across tools (Linux preferred, but I could stomach Windows if I had to!) which can duplicate such discs and produce errors in the output at the same block as the input? (I assume any software on such deliberately-crippled media would check for the presence of known errors at install / run time) cheers Jules
