KIM-1 SBC

Fun little program running on my KIM-1

In this video I will explain how easy it is to work with you Peripheral Interface Adapter. And how to setup Port A or Port B as an Input or Output Port. Then how to view the Input Port or Store Data into your Output Port. After that we will write some simple code, to have your computer communicating with your project using the PIA adapter.

This is an update to my KIM-1 Piano. In this video I have modified my bread board to include 2 - 8 push down button arrays. I only had to modify my program by EORing all of the Port A inputs. by placing a 49 (EOR) FF at address 020F and 0210. Which I original had placed two NOPs (EA) in place, so that I would not have to number the entire program. As you can see in this video, I built a new bread board to accommodate the 2 - 8 push button arrays and I had to use an alligator clip to wire my bread board, as there was no room for the ribbon cable.

This is a simple program that creates a different sound wave, depending on which key you press. In this video I spend a fair amount of time explaining all of the unique issues that I ran into. In the hopes that I would be able to make everything about this program, perfectly clear. So, it does run a little long, but hopefully I will have made every aspect of this program a little easier to understand.

n this video we will go over the Mini Program C found in The First Book of KIM. In this program we will be introduced to one of the built in subroutines, know as SCANDS, that is used to display our programed values on the 6 - 7 segment displays. This short program has inspired me, to do something more then simply put some static numbers up on the displays, So, first I started by simply incrementing the first two digits on the right from 0 - FF in Hex. After that, I was able to convert this program to count in decimal, from 0 - 99 which took a lot more finessing to accomplish.

In this program I will start incrementing the Minutes first and then go on to build a full Clock program.

In this video we will be covering the second mini program found in The First Book of KIM called Mini Program B In this program we will be filling 10 memory location with all Zeros. and still have time to do the three exercises , as well as a few more valuable methods for trouble shooting any problems that you might run into in the future.

This is an instructional video that you will find in The First Book of KIM

This little project can be found in the KIM-1 Users Manual on Chapter 5. It is a basic Tone Generator. We will briefly go over the circuit and the code that goes with it. This is a fun little project to get you familiar with using the external PA port on the 6530-003 ROM-RAM-I/O Timer to communicate with peripheral devices.

In this video we will demonstrate how to save a program to tape and how to load that program back into our KIM-1

This is a video of the PLL SET program running on an original KIM-1 to resolve a problem with loading a program from tape. You can find this program on page 129 of The First Book of KIM.
