- Computus Interruptus, Part 1Or, The Joy Of Using Interrupts On Your Computer “All right”, comes the chorus, “what’s an interrupt, and why should I care?” I’ll admit, it’s possible to lead a normal, happy life even if you’ve never heard of an interrupt. But in that case, you’ll have missed something that’s at least lots of fun and,…
- Computus Interruptus, Part 2How Does The Demonstrator Work? Pretty well! Seriously, let’s first look at what the demonstrator sets up in memory, and then we’ll see how it all works together. Understanding this description will require a bit of knowledge of machine code, but only a bit. The demonstrator has been written to be understood by as wide…
- Computus Interruptus, Part 3If you try to relocate the machine code to the same 16K memory block as the display file (16-32K), you will notice that the quality of the picture degrades badly when it’s running. The servicing of interrupt mode 2 confuses the hardware that generates the display, when both are trying to operate with the same…
- Computus Interruptus, Part 4The interrupt driven print-screen program we’ve been playing with is just about “all used up” as a learning tool. Its main advantage was that it was very short, and could be easily entered. Unfortunately, it required a T/S 2040 printer to operate. Now we’ll learn some new things by working with an interrupt driven sprite…
- Computus Interruptus, Part 5Non-Maskable Interrupts You’ll need an “NMI Switch”, RAM in the DOCK bank and the ability to copy the T/S 2068 HOME ROM to the RAM. Basically, the NMI works as follows. When the NMI line at the rear connector is brought momentarily to ground, the computer stops what its doing and starts executing code at…
- Computus Interruptus, Part 6Now, it’s time to fire up your T/S 2068. Type in and RUN the listing below. This must be done with the original Timex ROMs in control. When the program runs, it will SAVE to tape a “TS2068 Enulator” program. The program will take a fairly long time to run before the SAVE message appears,…
- Computus Interruptus, Part 7Now we’ll cover a couple of tricks we can do because the maskable interrupt is synchronized with the computer’s video output. Since we’re looking at interrupts and video, we should first take a quick look at how a video image is formed. A monochrome television or monitor can only produce a single tiny spot on…
- Computus Interruptus, Part 8Now we’ll return to the interrupt driven sprite program. When you type RANDOMIZE USR 64776 to start the program, the little sprite will bounce happily around the screen, and will keep bouncing, even while you type in your own BASIC programs and run them. While you run a BEEP command or do I/O to the…

Yes, the illustration on page 251 of the user’s manual that comes with the T/S 2068 does explain it. Still, most everyone reacts with the question, “Why?” This configuration was made to dovetail with the Z80…
