Since the dawn of computers, we’ve tried different ways to store data. These days, you grab data over the network, but you probably remember using optical disks, floppies, or, more recently, flash drives to load something into your computer. Old computers had to use a variety of methods, such as magnetic tape. But many early […]
The solenoid and punch side of the machine. {Credit: Simon Boak) Although [Simon Boak] had no use for an automatic paper tape punch, this was one of those intrusive project thoughts that had to be put to rest. With not a lot of DIY projects to look at, the first step was to prototype a […]
If you were one of the earliest of early adopters in the home computing revolution, you might have had to settle for paper tape mass storage. It was slow, it was bulky, but it was what you had, and that gave it a certain charm that’s hard to resist. And that charm is what [Joshua […]
Though it is many decades since paper tape was commonly used as a data input or storage medium, it still holds a fascination for many who work with computers. Over the years we’ve featured more than one paper tape related project, and the latest to come out way is [ColemanJW2]’s 8-bit ASCII paper tape generator. […]
Building a paper tape reader by itself isn’t super complicated: you need a source of light, some photoreceptors behind the tape to register the presence of holes and some way to pull the tape through the reader at a reasonable rate. This latter part can get somewhat tricky, as Usagi Electric‘s [David Lovett] discovered while adding […]
After previously working out a suitable approach to create a period-correct paper tape reader for his tube-based, MC14500B processor-inspired computer, [David Lovett] over at the Usagi Electric farm is back with a video on how he made a working tape reader. The assembled paper tape reader as seen from the front with tape inserted. (Credit: […]
Over at the [Usagi Electric] farm, [David Lovett]’s custom 1-bit, vacuum tube-based computer (UEVTC for short) has been coming along well the past years, matching and exceeding the Motorola MC14500B 1-bit industrial control unit (ICU) that it is heavily inspired by. What is still missing, however, is a faster way to get data into the […]
The recent Cyphercon badge featured a very clever integrated paper tape reader, and had the hidden feature of a party mode in which all its lights would flash. When [Gigawatts] discovered this after the conference had ended, it was too late to find the tape to activate it. The solution? Build a tape emulator with […]
