There AltairZ80 Simh emulator can run a wide variety of configurations, so it gets a bit confusing. To work with images compatible with a real Altair floppy and with the Altair Clone, here's what I'd recommend:
1) Download the emulator executable (altairz80.exe) at
http://www.schorn.ch/cpm/zip/altairz80.zip.
2) Download the Burcon CP/M 2.2 software at
http://www.schorn.ch/cpm/zip/burcon.zip3) Optionally, you can also download additional Altair software at
http://www.schorn.ch/cpm/zip/altsw.zipUnzip each zip file into their own folders. Copy the altairz80.exe file from the altairz80 folder into the burcon folder you created and also into the altsw folder you created.
Start inside the burcon folder. Double click altairz80 to run the emulator. At the sim> prompt, type "do cpm" and press return. Burcon CP/M will boot. The CP/M program "R.COM" is used to read a file from the PC into the CP/M file system. The program "W.COM" is used to write a file from CP/M to the PC. The files read and written must be in the burcon folder (i.e., the same folder from which altairz80 was executed).
You can copy any of the disk images from the Altair Clone directories into the burcon folder and work with them as well. Either name the disk image "cpm.dsk" or you can edit the file "cpm" (you may want to change the name to "cpm.txt" so it is easier to bring up the text editor) and put in the disk image file name where you see "attach dsk0 cpm.dsk" line. Note you can also add additional disks (up to four total) with additional "attach" lines using "dsk1" "dsk2" etc. Note that the simh boot command becomes "do cpm.txt" if you add the ".txt" file extension to the command file.
In order to get "R.COM" and "W.COM programs onto a new disk, first save these programs to the PC from the original burcon CP/M disk using W.COM to write R.COM and W.COM to the PC. Then boot the new disk image onto which you want to load these programs. Once CP/M is running and you have the A> prompt, type ctrl-E to exit to the simh console. At the sim> prompt type "load r.com 100" and press return. This puts the R.COM program into 8080 memory at 0100h. Then type "g" and return to return to CP/M. Press return once or twice to be sure you have the A> prompt. Type "SAVE 16 R.COM" to save the read program from memory into a file. Now use R.COM to load W.COM and you're all set.
Note that the CP/M versions in the altsw folder are customized for the emulator and may not be ideal versions of CP/M for the Altair Clone or for a real Altair floppy.
