Sonderdisk - Public Domain

Special disks are a series of commercial programs which were distributed by Maxon Computer GmbH at a price of less than 100 Deutschmarks. Unlike the Special-Line-Disks of the Heim Verlag, the special disks were never published on CD. Whoever owns such a disk should archive it immediately. A database with descriptions and screenshots of the programs was published with the public domain database of Maxon.

  • Ordne HDB
    After frequent writing and deleting on hard disk, the related parts of a file (cluster) are often widely scattered, which leads to considerable delays. The program completely rearranges the structure so that all clusters of a file are directly adjacent to each other. Further functions: rescue or regenerate deleted files, restructuring of directory entries, FAT analysis, occupy defective sectors, show folder structure, change names (disk/folder) and others. ORDNE HDB supports the drivers AHDI, CHDH, ICD, Eickmann-HDplus and Vortex.

  • Chip-Copy
    Extremely flexible file utility as program and accessory. With Chipcopy you can copy, move or delete files and complete folders at any time according to numerous selection criteria. By logical connection of several filters you can create optimal selection criteria and thus e.g. quickly make backup copies of all texts of the last week and the corresponding text program. Each filter consists of several wildcards and can additionally be limited to the time period of creation. CHIPCOPY can copy and format complete disks and print directories according to the same selection criteria.

  • Fatspeed II
    FATSPEED II accelerates hard disks under TOS 1.0 and TOS 1.2 by up to 1000%, making each disk as fast as with TOS 1.4. With the old TOS versions, time is wasted when writing to disk mainly by organizing the FAT, less by writing itself. Especially with full disks (which disk is already empty?) write accesses became a real test of patience. FATSPEED II optimizes this and achieves amazing write times. A restore for backup files takes not 2 hours but 20 minutes, saving the desktop info 2 instead of 7 seconds, a full folder one instead of ten minutes (only useful for TOS 1.0 or TOS 1.2).

  • Textractor
    Have you ever looked for a file whose name you can't remember? But you know words from the content and that's where Textractor comes in. Textractor searches for keywords within texts, letters or source code on your hard disk or disk, also as an Accessory, because mostly during a text editing a text has to be searched for. Textractor extracts a list and immediately shows the name of the file with the found keywords, including context. At the push of a button, the entire file is loaded and displayed (ASCII or Wordplus format). You can choose to jump to the terms found in the entire file, or you can view only the text group around your keywords to condense the information. Individual partitions, up to three file filters, a maximum of three path specifications and date specifications can be used to limit each search. Textractor also offers... - allows the use of synonym lists (e.g. printer=printer=plotter) - saving and loading of complete searches and/or settings - every character can be converted via an ASCII filter table

  • Little Boot
    You know the situation - you use several programs that either do not understand each other or simply need to run in a different environment. Changing the names of the autostart programs, accessories, desktop infos and Assign SYSs manually is extremely impractical. LittleBoot makes this a breeze. Certain settings can be defined as a set and activated with a click. LittleBoot is activated in the auto folder and runs (nevertheless) in an attractive GEM environment. Optionally, a welcome screen is displayed or a password is requested when starting the computer.

  • Needles & Pins
    Font editor for download fonts. Almost all matrix printers offer to load and print with self defined fonts. Needles and Pins now allows the comfortable creation of these fonts and helps your printer to create new typefaces. Works for example with WordPlus, Edison, Tempus or Harlekin. Download fonts are printed with maximum speed. A given font can be automatically sent to the printer when the computer is started.

  • Schlagdame
    The counterpart to DAME. Here the one who loses all the stones wins. A very interesting variation. The pieces are selected by mouse, the moves are logged and analyzed. Different playing strengths, move suggestions, training mode, as well as loading and saving a game. Different board sizes.
Sonderdisk 083
  • DPE
    DPE is used to display measurement series.The program, which is fully integrated into GEM, allows various display modes, logarithmic scale, automatic scaling, range selection by mouse, regression (Lin, Pot, Exp, Log), display of error bars, as well as the additional display of a function f(x). The editor is used for manual input of the measured values, respectively for changing the imported data, which is especially comfortable due to the block functions (Cut, Copy, Paste). DPE supports the import of measured values via measuring instruments connected to the serial interface (RS 232) and is therefore well equipped for use in laboratories of all kinds. Of course, data can also be entered manually or read from an ASCII file...A calculator with the functions "LN, SIN, COS, TAN, COT, SQR, EXP, INT, ABS, FAK, SGN, DEG, RAD, RND,..." and the constants "PI, NA, k, Vm, e, me, u, h, G" is also helpful. GDOS is necessary for this.

  • Delite
    With Delite there is finally a real GEM shell available for GFA-BASIC developers. A menu bar, which offers the most important file and setting functions, is available as well as an own desktop with icons for GFA sources, RSC files, finished compilates, text files. Even the obligatory trash can has its place. Of course, all installed accessories (as you would expect from a GEM program) can be used without any restrictions: Every GFA-BASIC project can be placed as an icon on the desktop and loaded into the interpreter with a double kick. For each GFA source an individual setting of parameters, compiler/linker options and environment variables can be defined and automatically saved. This ensures that you will always find the Delite desktop with all your projects as you left it. The compile and link process can be started by pressing a key. Finished compilations appear automatically as icons on the desktop and can be started directly. With an appropriate resource construction set, the popular GEM resources can also be loaded and edited directly with a double click. Switching between the GEM interpreter and RCS is thus reduced to just a few mouse clicks, without tedious searching for the appropriate files. Also ASCII text can be loaded comfortably by double-click into an external text editor, or be transferred to a "View" program (e.g. GUCK). If you program smaller and larger projects (especially GEM programs) in GFA-BASIC, Delite is the ideal development environment.

  • Karteye
    Manages data of all kinds. Featuring macro functions, mask editor, mailing lists and numerous data masks
Sonderdisk 087
  • EMU-65x02
    Fast emulator and development system for the processors 6502, 65C02 and 65SC02. The processors can be emulated within a GEM window. The EMU 65x02 is perfectly suited for programming the 65x02. A program can be developed, assembled and generated as finished code e.g. for an EPROM of a single chip card. But before you burn an EPROM, you better try out the program. No problem for the 65x02 emulator. The assembled program runs on the ST/TT in a virtual screen (25*80 GEM window). A debugger makes it possible to trace the program, to stop it at a certain address or at a breakpoint, to trigger single stepping and IRQs, or NMIs. There the state of the CPU can be displayed and changed. A help system gives information about assembler directives and operating system functions, which are available to the assembler in the ST (screen clear, read/set cursor position, keyboard query, character output, register display, string output, ...). 65x02 runs as GEM program or as an accessory.

  • DarkStar
    Animated screensaver. A screen saver is used to protect the screen (oh what?!). But screen savers that darken the image are obsolete, so now there is DARKSTAR. After an adjustable time, it offers either a flight through space with animated stars or calculated characters whose shapes are constantly varying. DARKSTAR is multitasking capable, i.e. it lets GEM programs continue to run when the image is switched to dark. DARKSTAR runs in all original resolutions.

  • DSP-Kit 1.09
    Since the release of the FALCON series, digital signal processing has been on everyone's lips. Although the DSP-Kit is not (yet) based on the FALCON-DSP, it allows a wide range of simulations of digital signal processing systems - even on "normal" ST/TT's. An ingenious graphical representation of signal processing components and their signal flow circuitry allows (besides more abstract topics like control engineering) also the audible (!) reproduction of sounds (e.g. sound synthesis) on the monitor speaker, a D/A converter on the parallel port (building instructions included), or the DMA sound unit of the STE/TT. Filters of first and second order, characteristic curves, rectifier, sample & hold, signal and spectral display (FFT) incl. optional distortion calculation, delay, integrator, differentiator, subsystems and many more are available. Everything is fully GEM compliant (with WINX max. 31 windows) and very easy to use. The ideal tool (or even the ideal playground) for communications and control engineers who want to "try it out" themselves.
