DOS 1.25 on SIMH 8086 emulator

[10nitro]

I'm trying to get MS-DOS 1.25 (from here)to run in an emulator, right now the one provided on the same page (the Linux binary link). The build I received is V3.8-1 build 1254 (scp created Feb 9 2009 at 18:10:22 with gcc 4.2.4)

I put the emulator in the same directory as the extracted MS-DOS files, set it to executable, then try to run it with

./altairz80l msdos125

It looks very much like I am successfully running MS-DOS 1.25, but the output looks like I've been running "cat /dev/urandom" for an hour. (and so does the text when I type)

Any ideas on what's wrong?

[edit:] I attached the output I get at first. At this point it appears to be at a prompt, as pressing any key triggers a response.

Did DOS even run on the Z80? I thought you needed a 8088 or 8086 for that

Maybe you can manage with freedos or dosbox, perhaps?
Did you think of those solutions?

It's called the Altair Z80 simulator, but it emulates several processors (according the page I got it from, 8080 CPU, Z80 CPU and 8086 CPU). I'm using the hardware configuration file provided with the DOS download.If I were to just type "./altairz80l", then it would drop into a "sim>" prompt to enter hardware configuration commands. Or I can run it with a configuration file that has all the necessary commands in it.
I recieved 4 files with the MS-DOS download, 2 disk images (msblank.imd/msdoscr.imd), a pre-boot program ("SCP 8086 Monitor 1.5", mon.com), and a hardware config file (msdos125).
The The first command in msdos125 is "set cpu 8086". And the 8086 emulator defiantly works, because I have gotten 86-DOS 1.00 (which MS bought and renamed MS-DOS) to run fine.

As a note, this and all of the SIMH emulators are available in the Ubuntu package "simh", but are outdated (the z80 in the package is V3.7-0, the one I just downloaded is V3.8-1), and does not appear to handle the config file:

Altair 8800 (Z80) simulator V3.7-0
msdos125> set cpu 8086
Non-existent parameter

I am aware of these, but I'm not doing this for practical reasons, I just want to emulate every version of MS-DOS I can.

I need to dive into these, look s like a fun exercise. Might take a while though. But it loooks like a story of my life...
