I plan to use it to port the Netware emulator from > Linux some day (may be not very soon). looks like a very nice piece of work. I was wondering if someone has been working on pcemu to add more features. Here are some projects I had started working on but did not complete. They are listed in order of importance. 1) 286 emulation (at least real mode). I have included some 286 instructions, but other are still missing. The problem arises because a lot of compilers produce 80286 code by default, even though there is no special requirement for that, and the poor emulator dies when it finds them... MAIN USE: various programs. 2) PCemu in an xterm. Many programs are text only, and it would be very nice to be able to run them in a text window, e.g. an xterm or so. I spent some time hacknig the x11 module and now my development copy is able to produce textual output in the xterm from which the pcemu has been started. Input is a bit more critical because the simulator wants make/break events from the keyboard, whereas the tty cannot supply such events. Also, some special keys (function keys etc) are not directly available. Anyways, my code is almost working, if someone wants to take it over just let me know. MAIN USE: our library has several databases on CD, with a DOS, text-only browser. They have a multiuser licence (and in some cases a site licence), and the way it currently works is exporting via NFS the database, enabling clients on demand. This does not work over a dial-up connection (well, I did it once, and it is not _that_ bad, at least for some programs). Being able to run PCemu in an xterm would make things much faster. 3) cga/ega/vga emulation. It should not be that hard for someone with a little bit of X11 knowledge. Not very important, but some programs still like to produce some graphic output.
