Sorry I' ve been a lurker so long after subscribing. I had a problem in my e-mail configuration and, coupled with some congress travels, missed most list messages until I noticed today. Regarding the disassembler, has anyone tried the one derMouse included in his emulator in TUHS? I have also found another PDP11 disassembler (for RT11) at http://ftp.dbit.com/pub/pdp11/rt11/ For the bold, there seems to be another PDP11 disassembler in BBC basic at http://mdfs.net/Software/PDP11/ this one comes with an assembler AND SOME UnixIO.mac library which leads me to suppose it may work on a.out files. It may probably be used under a CP/M emulator with BBC Basic. Finally, what about IDA, the interactive disassembler? It once claimed to support PDP11 and old versions may be around (the 4.9 is free but I ain't sure it still supports PDP11). Any of those should help build a current one for the a.out format. BTW, and just for fun, I just found out about pdpxasm, which says is a "PDP-11 cross-assembler, cross-linker, and cross-disassembler run under DOS, by Strobe Data Inc." and is also freely downloadable. Might be fun to see what its cross-disassembler produces. j -- These opinions are mine and only mine. Hey man, I saw them first! José R.
