Many laser printers last for years, so businesses often keep older laser printers around even after upgrading other hardware. Many older laser printers use a parallel port interface rather than the ...

If your small business is typical, you want to get the longest lifespan possible from your tech investment, and therefore you may have an older dot-matrix or laser printer with a parallel port that ...

Any peripheral component can be controlled by the 25-pin parallel port by assigning a high & low or ON & OFF state to each pin. During the design of the project, a Super Nintendo Entertainment System ...

I have a PC-based DSO that connects via parallel port that I'd like to get working via USB (preferable) or at least ExpressCard. I picked up a USB-parallel adapter from MicroCenter thinking it would ...

High-resolution temperature sensing at low cost is possible using only one chip attached to the PC's parallel port (Figure 1). The Dallas Semiconductor (www.dalsemi.com) DS1722 digital thermometer ...

In the olden days, plugging something into your computer—a mouse, a printer, a hard drive—required a zoo of cables. Maybe you needed a PS/2 connector or a serial port, the Apple Desktop Bus, or a DIN ...

It is a great shame that back in the days when a typical home computer had easy low-level hardware access that is absent from today’s machines, the cost of taking advantage of it was so high.

The circuit shown in Figure 1 steals energy from a PC's parallel port or from any limited-energy source. To use the available energy, such power-conversion applications usually require very high ...

For PCI bus interfacing, the OX16PC1952 brings together a PCI interface, two high performance serial channels, and a parallel port in one compact, 128-pin TQFP package. This integrated bridge device ...

While doing my usual surfing routine today, I came across an interesting read over at CNET. Some creative artists have made their mark in the oddest of places, a microchip. Some of the designs are ...

So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc needs ...

FM synthesis is the sound of the 1980s, it’s the sound of shopping malls and Macintosh Plus. It’s the sound of the Motorola DynaTAC, busts of Helios, and the sound of vaporwaveサ閲ユ. The chips most ...
