DotXT

An IBM PC emulator written in C# with dotnet 9.0. It runs on Linux and probably on other C#/.NET platforms as well.

Please no "pull requests" (via github or other way), but tips/hints/suggestions are welcome.

compiling the emulator

• On Linux dotnet build -c Release After a while you'll find a programfile called "bin/Release/net9.0/dotxt".

• On Windows dotnet build -c Release After a while you'll find a programfile called "bin\Release\net9.0\dotxt.exe".

If you like, you can copy that dotxt(.exe) file into the demo directory.

running it

dotxt -R roms/GLABIOS.ROM,f000:e000 -X harddisks/demo.vhd -p cga,vnc,5900 -R roms/ide_xt.rom,d000:0000 -R roms/GLaTICK_0.8.5_AT.ROM,d000:2000 -S -O rtc

Note that you need to use a VNC-viewer to connect to the emulator. E.g. "vncviewer localhost:0" (for example https://www.tightvnc.com/ should work).

The example above runs DotXT with:

• GLABIOS installed (-R roms/GLABIOS.ROM,f000:e000)
• an XT-IDE harddisk (-X harddisks/demo.vhd -R roms/ide_xt.rom,d000:0000)
• a CGA-adapter exported via VNC at port 5900 (-p cga,vnc,5900)
• an RTC (-O rtc -R roms/GLaTICK_0.8.5_AT.ROM,d000:2000)
• and throttles the speed to emulate a 4.77 MHz PC (-S).

If you would like MIDI-support, add "-O midi" to the command line. Adlib support uses "-O alib". Listen to it via RTSP (e.g. on linux: gst-launch-1.0 rtspsrc location=rtsp://localhost:5540 \! decodebin \! audioconvert \! audioresample \! autoaudiosink). Run dotxt -h to get a list fo commandline parameters. In the console ("==>" on your screen), you can enter e.g. "help" to get a list of commands. For example for changing the floppy drive image for an other.

==> you need to enter "go" (+ enter) to start the emulation!
