The data can either be a value on it’s own, or it can point to another variable memory location that contains a value.

Each address contains either a command or data.

These emulators will help you to understand that computers are simply a list of memory addresses. In today’s world, computers tend to use a lot of “smoke and mirrors” to make things easier for the programmer. Together, these emulators give you a good understanding of how computers actually do work. After that you compile whatever sections you wish to use. In short, to get the Z80pack working, you simply download and extract it. With all of these different emulators available, you will get a feel for how computing was in the 70’s and early 80’s.
#IMSAI 8080 EMULATOR SIMULATOR#
The Z80 Simulator compiles in much the same way as the others. You can actually spin the model around to see every side of the IMSAI 8080. The IMSAI simulator works in much the same way.Īs you can see, the IMSAI simulator has a 3d mode if you wish to use it. Once you get the hang of one of the packages, you’ll be able to compile the others without the need to follow many instructions.
#IMSAI 8080 EMULATOR HOW TO#
I quickly realized that I had to click the word “ON” and not the power switch itself.Īgain, TechTinkering has a good article on how to compile this code. In this case, I had a hard time getting the Altair 8800 to power on.
#IMSAI 8080 EMULATOR CODE#
In order to use these, you will want to compile the frontpanel code which is in a separate folder. The Z80 Pack also contains simulators for the Altair 8800 and IMSAI 8080. However, if you start cpmsim using the “work” script in the previous link, be sure you understand where your “i” drive is located. This is a good game to set up just to ensure your CP/M is working under Linux. Lawrence Woodman wrote some good articles at TechTinkering, and you can follow his instructions at this link.Īnother good article is by Kenneth Boone on how to run Zork1 under CP/M. After that, you can build the files to make the cp/m emulator work. Basically, you simply go into the srcsim, and srctools directory within the cpmsim folder. While in your linux terminal, you will need to build the source code. After that you’ll have a good start on setting up each type of emulator. I’ll post some good links below in each section to get you started.Īfter you extract the z80 pack, simply rename it to “z80Pack”, and move it to your home directory. There are already good instructions on the internet for compiling the source of the Z80 pack. Once you download the emulator in Linux, you can extract it using tar xzvf (filename). Download the Z80 PackĬurrently, you can download the Z80 Pack from. However, if you had a terminal, it was definitely a luxury at the time. Originally, without a physical terminal, you program the Altair and IMSAI via front panel switches.
