Hello. Run codes for Q387 emulator V2.3 (the earliest version of which I could find on the Internet) will be given in this thread. You just have to put here your "Machine code" and just in case mention the Q387 version you have/want to use. No other personal information is required or contained in your "Machine code" which is a mere representation of your BIOS checksum(s). The emulator itself is available on many places around the net, for example:
http://www.irls.narod.ru/soft/q387.zip
http://www.radiofan.ru/soft/q387.zip
Unlike later versions this early 1991 version of the emulator is not compatible with EMM managers that use CPU's paging unit (in protected mode) to emulate EMS memory because the emulator was designed to be the only VM86 hypervisor in order to hook interrupts with dos extenders. Therefore this version can coexist only with XMS managers like himem.sys
This thread is intended to draw attention of the authors of this very interesting emulator. Maybe they will be willing to share the source code or other interesting info about this marvelous piece of vintage software after so many years. It will be interesting to collect all versions of Q387/Q87. Until now I have found on the net versions 2.3, 3.1, 3.5, 3.6, 3.65, 3.66, 4.02, 4.13
Later on maybe it will be possible to provide "run codes" for later versions of Q387/Q87. Right now only V2.3 is supported. I even suspect that at some point (after certain version) there were separate demo (that was impossible to activate via any run code) and full versions. I hope some of you that had bought this software could shed more light on to this and thus help in reversing newer versions. Yes, patched/cracked demo versions existed in the past but it is much more cleaner to make it run without modifications the way it was intended to run...And it was much more interesting to figure out the registration algorithm considering the fact that mathematicians were among the creators of this NPU emulator.
