Free unix spectrum emulator software for linux

libspectrum is a library designed to make the input and output of some ZX Spectrum emulator files slightly easier.

libspectrum is intended to be usable on Unix variants, Mac OS X and Win32. Currently, it is mainly (only?) used by Fuse, but other Spectrum emulator and utility authors are encouraged to use it.

Which formats does it support?

read/write: .z80, .szx, .sna
read only: .zxs, .sp., .snp, +D snapshots

Tape images:

read/write: .tzx, .tap

Compressed files: reading of gzipped and bzipped files is transparently supported.

Wide Area Link Emulator enables you to set and test various parameters of a WAN access link (also known as a bottleneck link) before testing on a fully-functional network.

Any ISP has a high bandwidth LAN (of the order of tens of Mbps, e.g. Ethernet) and a WAN access link with relatively low speeds (of the order of a few Kbps to a few Mbps). To be able to evaluate the ISPs performance, actual tests will have to be conducted on a live, fully functional network. This would imply enabling certain features in communication equipment which could be detrimental to the proper functioning of a commissioned network. To address such a problem of being able to characterize/quantify the network operation in terms of its performance with respect to various parameters, a test-bed emulating the ISPs connectivity to the Internet would be an ideal solution.

An important factor in setting up such a test-bed, is emulating the WAN Access Link. Using complex hardware is costly. Such a link can however be easily implemented by emulating the scenario on popular physical technology such as Ethernet. By changing the TCP/IP stack on a Personal Computer, the rate at which packets are injected into the network can be controlled and other necessary features can easily be added.

WALE was implemented in 2 phases and the first version can emulated bandwidths up to 8Mbps and uses FIFO queues with drop-tail.

WALE v2 can emulate bandwidths of up to 80Mbps(a 10-fold improvement over version 1) due to the stripped down version of Micro-second resolution timer being used in the Linux kernel. WALE also implements differentiated services are recommended by IETF. A hash-based packet classifier is used to classify packets into one of 3 queues (Expedited Forwarding, Assured Forwarding and Best Effort). A simple priority scheduling has been implemented between the queues.

Version 2 has been implemented in the Generic Device Layer of the Linux Kernel. The kernel version is 2.2.19. WALE2 kernel patch can be downloaded here. An ncurses based front end has been implemented for setting and viewing various parameters of the bottleneck link.

Unix I-Ching Generator project is an I Ching generator for the Unix command line.
It accepts questions and generates responses that can be looked up in the I Ching (a Chinese divination book).
It is designed around "spiritual algorithms", that is, algorithms that make some sort of sense spiritually, not just programatically.
This is software that automates the casting of I-Ching hexagrams. It does not provide the interpretations or readings of those hexagrams.
It merely outputs a mandella of two hexagrams and then informs you of the numerical identity of each hexagram.
Enhancements:
- Moved global options to header file. (ARJ)
- Changed unigram::cast() so that it relied on globals. (ARJ)
- Fixed spelling errors. (ARJ)

Jagacy 3270 Emulator is a feature-rich 3270 terminal emulator. It supports SSL, TN3270E, and over thirty languages. The project does not contain the screen-scraping library, and is a cost effective solution for a stand-alone Java 3270 terminal emulator.
The emulator can be configured to help create screen-scraping applications. Developers can also develop their own custom terminal emulators (with automated logon and logoff). Jagacy 3270 screen-scraping is faster, easier to use, and more intuitive than HLLAPI. It excels in creating applications reliably and quickly.
Main features:
- 100% pure Java.
- Feature rich 3270 terminal emulator.
- SSL support.
- Extended TN3270 (TN3270E) support.
- 17 different terminal types (including 132 columns).
- Internationalization support. Over 30 different languages supported.
- Configurable using properties, if desired. No changes necessary when host name or screens change.
- Easily create a custom 3270 terminal emulator.
- Small footprint (less than 150K). Runs efficiently within the Eclipse and NetBeans IDEs.
- Can display the 3270 session in a window while an application is running.
- Includes a full-featured 3270 terminal emulator tailored to developing and debugging applications.
Enhancements:
- Add features/limitations/changes here

This is a collection of scripts which is used to manage the creation of Slackware packages. This framework is designed to make it easy to add packages to the collection and to easily tweak package parameters for testing and deployment.
The framework currently has a lot of parameters, and also has basic frameworks for CPAN packages. It is possible to add more frameworks and tweaks for other package networks as well, such as the PHP and Python archives, and these are in the works currently.
Enhancements:
- This marks the start of the new style of build scripts. These are much more modular, and have a consistent set of shell functions and variables which work in their defaults for most situations, and can be redefined by a package file to do special setup or other functions
- which some packages may require.

CUPS provides a portable printing layer for Unix(r)-based operating systems. Common UNIX Printing System has been developed to promote a standard printing solution for all Unix vendors and users.

CUPS provides the System V and Berkeley command line interfaces, and uses the Internet Printing Protocol ("IPP") as the basis for managing print jobs and queues. The Line Printer Daemon (LPD) Server Message Block (SMB), and AppSocket (a.k.a. JetDirect) protocols are also supported with reduced functionality.

CUPS adds network printer browsing and PostScript Printer Description ("PPD") based printing options to support real world printing under UNIX. It includes an image file RIP that supports printing of image files to non-PostScript printers.

A customized version of GNU Ghostscript 7.05 for CUPS called ESP Ghostscript is available separately to support printing of PostScript files within the CUPS driver framework. Sample drivers for Dymo, EPSON, HP, and OKIDATA printers are included that use these filters.

Unix::Mknod is a Perl extension for mknod, major, minor, and makedev.

SYNOPSIS

use Unix::Mknod qw(:all);
use File::stat;
use Fcntl qw(:mode);

$st=stat(/dev/null);
$major=major($st->rdev);
$minor=minor($st->rdev);

mknod(/tmp/special, S_IFCHR|0600, makedev($major,$minor+1));

This module allows access to the device routines major()/minor()/makedev() that may or may not be macros in .h files.

It also allows access to the mknod system call.
