The Monsputer is a Z80 computer developped with old chips (and some new) collected over the years. It has about 2M memory, clocks at 4.0MHz, has serial ports, 1 parallelport, 1 CAN bus, 2 SPI, 1 I2C, a RTC and other features. It supports interrupts mode 2 but not DMA.
...Win NT/2K/XP/7/8/10/11, Linux/i386/AMD64/ARM, FreeBSD and MacOS X kernel driver and development library to control serial CBM devices, such as the Commodore 1541 disk drive, connected to the PC's parallelport via a XM1541 or XA1541 cable. Fast disk copier included. Successor of cbm4linux. Also supports the XU1541 and the XUM1541 USB devices (a.k.a. "ZoomFloppy").
WxPic allows, with a PC and an adapter (programmer), to program a PIC micro-controller, by loading a HEX file, reviewing and/or editing the configuration or memory and writing and/or verifying the device flash memory.

This C++ and Qt based project provides an easy way to control the step motor boards PAO-3M and SMK-4M-4A from Grummes Elektronik GmbH from within your own application. Interfacing is done using the LPT parallelport.
Software for controlling vending machines. Allows users to preload credits to their user accounts
and use them to buy various goods from one or more vending machines connected to
computer via parallelport relay interface.
hardware log monitor that will display log behaviour via various hardware (parallelport, USB devices, ...). You can specify pattern(regexp) in log(s) on which hardware will turn on. It has also some unique ways of visualization of log files.
The libtlc54x helps you to communicate with the Texas Instruments TLC548/549 A/D-Converter via serial or parallelport. With the library you need only three steps to open the device, read the data and close the device.
Parapin makes it easy to write code under Linux that controls individual pins on a PC parallelport. This kind of control is very useful for electronics projects that use the parallelport as a generic digital I/O interface (instead of as a printer port)
Uma API de C++ multi-plataforma que fornece fácil acesso à porta paralela. Com ela o desenvolvedor não se preocupa com inversões de bits e como o sistema lida com a porta. English: A C++ API for using the PC parallelport written in BR Portuguese
Input/output (IO) C library exposing a common API for real mode and permission-restricted access to parallelport under Windows, Linux and MS-DOS operative systems. It also allows pin-by-pin port access.
Cylon is a project to send various patterns to a simple LED display connected to the parallelport of a standard PC. The low-level drivers currently support Linux, but I have ported it to FreeBSD and Cygwin.
Currently-under-development library of OS-independent objects to provide complex parallelport control, high-resolution timers and other similar facilities needed when using PC I/O ports to control external digital electronics.
geniusvp2 is a SANE (http://www.sane-project.org/) backend for the GeniusŽ ColorPage-Vivid Pro II flatbed scanner. Currently, only the parallelport version is supported.
FIPP 4L is to provide a linux kernel driver and C library, which allow programming the Fischertechnik (R) parallelport interface (product ID 30520) in an easy way.
A nice tool for low-level managing of the parallelport and for experimenting with it.
It uses GTK+ 2 for the GUI and runs on Linux and Windows (with mingw32).
Simple GTK2 application allowing users to manually toggle devices attached to a parallelport device on or off (through the D0->D8 data lines), or run an automatic sequence based on a simple language contained in this program. Good for driving relays, etc
Eppnics: Electronic parallelport network interfaced control system. Eppnics allows you to control electronic circuits connected to a parallelport via a TCP/IP connection.
This program allows the user's laptop to act as a trip computer displaying fuel economy, speed, and other information about a car which is connected through a hardware device to the parallelport.
Linux/i386 kernel driver and development library to control serial CBM devices, such as the Commodore 1541 disk drive, connected to the PC's parallelport via a XM1541 or XA1541 cable. A fast disk copier included.
UniPIC is a GTK programmer software for PIC programmers based on Brian Lane\'s software that supports at least PIC16C84 and PIC16F84. It works with the parallelport and by default with microPIC Trainer.
