Using ! HP 2100 DOS

tip

If you have not already installed SIMH HP 2100 emulator, see the VirtualHub Setup tutorial on how to do so on Linux and Windows.

Extract the kit you downloaded. Inside you will find several files. Create a folder somewhere to store the files for this VM and move the file named DOS.disc into it.

Now we will create a config file for our VM. Create a text file called hp2100.ini with the following content in the VM folder:

set cpu 2116
set cpu 32k
SET CPU EAU
SET MP ena
set tty sc=11
set clk sc=12
set ptr sc=13
set tbg sc=17
set ptp sc=20
set tty autolf
set console del=177
set dpd dis
SET drc 720K
set drc sc=21
set drc ena
att drc DOS.disc
echo
boot drc
d s 1
go until "CO=CONTINUATION"
reply "CO\r"
go until ":DATE,XXXXXXXXXX,H,M"
go until "@"
reply ":DATE,10JULY1969\r"
go until "@"
go until "\r"
reply ":JOB\r"
go

Now open a terminal and move to the VM folder. Run the following command to start the emulator:

hp2100

After the emulator starts, type :LIST,X,1 and press enter. It will list all the files available on the disk.

That's it! We used ! HP 2100 DOS. We can create a shell script to make it easy to launch the VM.

Linux

Create a file called HP-2100-DOS.sh with the following content:

#!/bin/bash
hp2100

Now make the file executable:

chmod +x HP-2100-DOS.sh

Now you can start the VM using the shell script. For example, on KDE you can right-click the file and choose Run in Konsole or on GNOME, where you can right-click the file and choose Run as executable. The VM will start.

See the manuals section on the main ! HP 2100 DOS page to learn how to use it.

Windows

Create a file called HP-2100-DOS.bat with the following content:

hp2100

Now you can start the VM by double-clicking the shell script. See the manuals section on the main ! HP 2100 DOS page to learn how to use it.
