DJGPP is a complete 32-bit C/C++ development system for Intel 80386 (and higher) PCs running DOS. It includes ports of many GNU development utilities. The development tools require a 80386 or newer computer to run, as do the programs they produce. In most cases, the programs it produces can be sold commercially without license or royalties.

This file, jargon.txt, was maintained on MIT-AI for many years, before being published by Guy Steele and others as the Hacker's Dictionary. Many years after the original book went out of print, Eric Raymond picked it up, updated it and republished it as the New Hacker's Dictionary. Unfortunately, in the process, he essentially destroyed what held it together, in various ways: first, by changing its emphasis from Lisp-based to UNIX-based (blithely ignoring the distinctly anti-UNIX aspects of the LISP culture celebrated in the original); second, by watering down what was otherwise the fairly undiluted record of a single cultural group through this kind of mixing; and third, by adding in all sorts of terms which are "jargon" only in the sense that they're technical. This page, however, is pretty much the original, snarfed from MIT-AI around 1988. -- jpd.

Greaseweazle allows versatile floppy drive control over USB. Read and write your vintage floppy disks from your PC/Linux/Mac computer. This USB device lets you to connect an old floppy disk drive to your modern computer to read/write floppy disks from any system with Shugart standard drives (Amiga, Atarí, Commodore, Amstrad, Sinclair, PC, CNC machines, musical instruments, industrial equipment, and more.)

By extracting the raw flux transitions from a drive, any disk format can be captured and analyzed. The Greaseweazle also supports writing to floppy disks, from a range of image file formats including those commonly used for online preservation (ADF, IPF, DSK, IMG, HFE, …).

Greaseweazle V4 is the latest version, updated for mass production and with the following features:

Reads and writes 3″, 3.5″, 5.25″, 8″ disks (with suitable drive and cable)
Buffered outputs, for communicating with older 5.25″ and 8″ disk drives
Integrated power connector for directly powering most 3.5″ disk drives
Write-enable jumper can be removed for safer preservation of precious vintage disks
Supports floppy-modded 5.25″ drives
Supports Disk-Change detection as used by Rob Smith’s integration into the WinUAE Amiga emulator
3 user-definable outputs (eg. 8″ interface REDWC signal)
100% factory tested, and tested again by me before shipping
