2.80 had a problem displaying MCBs in memory dumps.

What problem you got ? you could try my dosbox build, I use it for IDA 6.6 https://mega.nz/#!YAcRCRaC!rmh_sleyg...VCCvDHTIgSzxQ8

I remembered in my old days, when I discovered the happiness of reverse
engineering DOS programs, I was a big fan of Sourcer, the "commented disassembler". IDA wasn't yet born!

The last version is available here:

Best regards

The debugger which I first used is Turbo Debug (Borland)

Debug.com and the Norton Guide with the list of interrupts IBM PC/AT. All in 5 1/4 diskette
GOD!!! I'm very old X-)

Sorry for the offtopic!

You should use dosbox or qemu for debugging or reversing. The main reason - these programs can emulate _every_ instruction and both opensource, so you can modify them to accompany your research.

E.g. you can add some unique feature: breakpoint on register value (break, when ax=3), breakpoint on memory value, breakpoint on register access, etc. This helps reversing a lot.

This is what i have in my DOSEXE tools folder:

If anyone needs something i can reup the complete collection to somewhere

Good old W32Dasm can never let you down !

Unfortunately, W32dasm (very good in its time,btw) only is for Windows programs, for msdos exes, you need IDA, or if running in DOS Sourcer (best disassembler for DOS)

Some user asked me for a updated version of DOSEXE pack, so i uploaded:

if you are familiar with IDA you should give it a try with the DOSBox plugin ;)

also give a try to Olly

Olly for DOS? :))

SoftICE
Turbo Debugger
debug.com
TRW

Pardon me bumping this old good thread, but
@an0rma1 - any chance to reup your great ancient DOS collection?
thx in advance
