Introduction to How Numbering Systems Work When working with any PLC such as ControlLogix (or any digital computer), it’s important to understand how numbering systems work. The numbering system we are all used to is base-10 (Decimal). Mainly, that’s because we have 10 fingers. In the decimal numbering system, there Read More »
Introduction to Programming PAL-1 With RC2014 In this section, we’ll set up communication for Programming the PAL-1 With an RC2014. Obviously, you can use a modern computer to program your PAL-1, or even it’s keypad. However, programming a vintage computer with another vintage processor gives you more of a vintage Read More »
Introduction to Using an LCD on RC2014 In this post, we’ll discuss Using an LCD on RC2014. Basically, in my setup I have a Zed PRO with a Prototyping module. If you don’t have a prototyping module, you can simply us a 74HCT688, and 74HCT32 to decode your port address. Read More »
Intoduction to the Prototyping Module for RC2014 The Prototyping Module for the RC2014 allows you to easily create projects to interface with your Z80 Projects that use the RC2014 bus. The Prototyping module does a lot of the work for you. It will decode the port address, and provide you Read More »
Introduction to the COSMAC Elf from PCBWay Building the COSMAC Elf from PCBWay is a quick, and inexpensive way to learn the COSMAC 1802. This is another project by Mr. Lunde. You can order the boards at this link. You will likely want to get the main processor (CPU) board, Read More »
Introduction to the RTC Module for RC2014 The RTC Module for RC2014 allows your system to keep time. This module allows you to take advantage of the timestamp feature in Z80DOS, and ZPM. You can purchase this module on Tindie’s website. The module I am using arrived as a kit, Read More »
Introduction to Tags and Datatypes It’s very important to understand Tags and Datatypes in the ControlLogix processor. The ControlLogix memory is made of of two main areas. Tags store data, and Tasks (logic) manipulate data. In contrast, the datatype is the way data is structured within a tag. When Read More »
How I’m Lowering the RC2014 Baud Rate My approach to Lowering the RC2014 Baud Rate is very simple. I simply looked at the original clock circuit, and built another frequency divider. In this post, we’ll discuss how easy that is to do. You already have the ability to set your Read More »
Introduction to using RS232 on the RC2014 In this section, we’ll be using RS232 on the RC2014. In this case, I just purchased a generic module for this. There are several reasons we might want to use RS232. In my case, I wanted to communicate to a BASIC module on Read More »
Introduction to the VT-132 Terminal Emulator for RC2014 The VT-132 Terminal Emulator for RC2014 allows you to connect a keyboard and monitor directly to your RC2014. This mostly eliminates the need to rely on a modern computer with a terminal emulator. The board comes as a kit from The High Read More »
