Because the Commodore Plus/4 keyboard is so different from modern keyboards, I devised a modern key nomenclature to identify keystroke combinations as shown in the table below:

I’ve spent much time with the Commodore Plus/4, a Commodore computer I didn’t own in the 1980s, and while I’ve worked my way through chapters one through eight of the user’s manual, there are many other things I want to do with this capable 8-Bit, and unloved, Commodore computer and today is one of those things! In this post and companion video, I describe my experience connecting a Commodore Plus/4 computer to the Particles! BBS using a Commodore4Ever provided Wi-Fi modem and Telnet. It’s a lot of fun and I hope you enjoy this experiment and jaunt down 1980/90s telecommunications lane.
This last chapter in the user’s manual takes us on a musical and noise infused journey through Commodore Basic and the Plus/4
VOL commands. The Plus/4 was not capable of the amazing sounds that come from it’s older brother and sister, the Commodore 64 or the 128. Heck, it wasn’t even as capable as the earlier VIC-20; however, with a little effort and creativity, you can put the two channels to use in business applications; the primary market for the Commodore TED series.
In this Commodore Plus/4 retroCombs episode and companion blog post, I cover Chapter 7, Using Graphics and Color, of the Commodore Plus/4 user’s manual. If you are eager to create images on your Commodore Plus/4, this is the chapter for you. Chapter 7 include information to PETSCII, colors, graphics modes, and other commands to create static images an animations. It’s a fun chapter and one that took quite a bit of time to prepare.
In this Commodore Plus/4 retroCombs episode and companion blog post, I cover Chapter 6, Beginning Bplus4/images/screen-window.pngASIC Programming, of the Commodore Plus/4 user’s manual. In this chapter, we begin where everyone should with their Commodore computer; learning the BASIC programming language. In previous chapters we have dabbled with BASIC; however, in this chapter, we dive in and learn the “basic” concepts you need to begin your BASIC programming journey.
In this Commodore Plus/4 retroCombs episode, I cover chapter 5 of the Commodore Plus/4 user’s manual. In this chapter, Number and Calculation, I learn how to use the Plus/4 as a calculator in immediate mode, create a function, and learn more about working with numbers in Commodore BASIC 3.5. I even combine some things we learned in previous chapters to amp up our programs. It is a packed chapter and even though I’m no math teacher;Getting Started_ I, “begin to acquaint you with some of the characteristics and capabilities of the Plus/4, and how to take the first steps toward programming with your computer.” We spend more time learning how to use the keyboard, correcting mistakes, creating simple programs, and then I shope I do the concepts justice. This is one chapter where I find the User’s Manual a bit lacking but adequatew you how to use windows on the Plus/4. No, not the operating system, but another unique feature of the Plus/4’s BASIC.
In this Commodore Plus/4 retroCombs episode, I cover chapter 4 of the Commodore Plus/4 user’s manual. In this chapter, Getting Started I, “begin to acquaint you with some of the characteristics and capabilities of the Plus/4, and how to take the first steps toward programming with your computer.” We spend more time learning how to use the keyboard, correcting mistakes, creating simple programs, and then I show you how to use windows on the Plus/4. No, not the operating system, but another unique feature of the Plus/4’s BASIC.
In this Commodore Plus/4 retroCombs episode, I cover chapter 3 of the Commodore Plus/4 user’s manual. This chapter is dedicated to Using Software and there are several ways to load and save software using; cartridges, datasettes, and diskettes. In this post and the accompanying video, I cover each auxiliary storage device in detail; however, I add a modern spin and instead of the original devices; I use a new 264 diagnostic cartridge, a Tapuino, and a Pi1541.
In this Commodore Plus/4 retroCombs episode, I cover chapter 2 in the user’s manual entitled, Using the Keyboard and the Screen. This chapter is chock full of keyboard instructions to help the user move around the screen, change text highlighting, modify lines of code, and create special characters.
In the next Commodore Plus/4 retroCombs episode, I open the Commodore Plus/4 manual for the first time to look at Chapter 1: Unpacking and Setting Up. Since the previous episode was an Open the Box, unpacking is already complete so this episode focuses on setting up the computer. Watch the video below and then come back to this post to read some additional thoughts, find links to everything mentioned, and learn a few more additional tips.
Today I unveil the first in a new theme of posts, retroCombs. This theme is devoted to my love of retro computing and gaming. I have a couple of retro posts on the blog, but now I have a brand theme to tie them together. The first post to receive the brand is part one of a new series on the Commodore Plus/4 computer.
As I progress through the user’s manual, I enter and execute the sample programs. The link below is to a
.d81.d64 image that below contains every program from each episode. Currently, the image is not complete since we still have several chapters to go.

I use the following file name convention to make it easy to locate specific programs:
Sample Program Name:
02 RCOMBS SCROLLC1P2-5RETROCOMBS.PRG
02C#- where # is the chapter number
RCOMBS SCROLL- my self assigned name for the BASIC program which will be immediately identifiable if you follow along.P#` - where # is the page number where the program is first referenced in the user’s manual
NAME- my self assigned name for the program
In the Commodore Plus/4 YouTube series, I work through each chapter of the Plus/4 user’s manual. I’ve scanned each chapter and provide those below. I will post new chapters with each new video.
