Projects Under Development

Nostalgy

new 3rd party operating system. Nostalgy Development Journal Reaktix Software Forum>Nostalgy>Introduction

Current features:

• OS loader
• Mathematical system calls
• IM1 poweroff/on
• IM1 [ON]-hotkey menu
• system information screen: displays OS version, calc type, Boot Code version, Battery state
• beginnings of a CLI, but no commands/input currently implemented
• Font:

• 4x5 fized-width font

Styles:

• inverting
• clipping

• Sprite:

• OR-ing
• XOR-ing
• clipping
• masking

Features already implemented, but not yet included:

• Grayscale: built-in 3,or 4-level grayscale support (based on Duck's grayscale programming package)
• Audio

• PlayWAV: built-in WAV playing capabilities
• PlaySound: built-in sound effects

• Media:

• Sprites: scaling

Planned features:

• RAM integrity verification and erasure upon non-integrity detection
• User interface: user-selected

• TIOS Homepage-style command line interface
• graphical user interface

• Linking:

• TIOS: TIOS-compatible routines
• non-TIOS: non-TIOS compatible routines, which allow for faster connections due to data compression before sending, and decompression upon reciving

• Compression/Decompression: built-in on-calc data compression/decompression routines with an assortment of different algorithms.
• Grayscale:

• user-adjustable interrupt speed (based on Duck's grayscale programming package, but the interrupt speed would be more acutely adjustable)

• RAM

• Executable RAM: user RAM programs would begin @ $8200, and thus allows for more executable RAM
• Stack Space: 3KB reserved stack space
• Data Management Table: VAT-like system for file management
• Folder support: the user can create and manage folders both in RAM and ROM
• Registry: System registry to allow for hook chaining
• Multi-tasking(?): allow up to three programs to be running simultaneously on RAM page 1

• ROM

• Apps: Flash space would be allocated in 4K or 8KB sectors, depending on the user's choice. This would be made possible by having all APPS use only relative jumps/calls

• Interrupts

• IM 1 hook: system-supported, chainable
• IM 2: system-supported, chainable routine

• Media:

• Video (like animated gifs?)
• Video-Audio sync-ing (AVIs?)

• Font:

• 4x5 variable-width font

Styles:

• grayscale
• centering
• word-wrap
• bold
• underline

• Keypad-Input

• "normal" keypad
• qwerty-style keypad
• user-remappable

• External Hardware Drivers

• PS/2 Keyboard Driver
• PS/2 Mouse

Projects Left to Simmer

MZip

On-calc data/program compression utility.

Current functional algorithms include:

• Fibonacci encoding/decoding [1]
• Elias gamma encoding/decoding [2]
• Elias delta encoding/decoding [3]

Future algorithms:

• Static Huffman [4]
• Adaptive Huffman [5]
• PuCrunch [6]
• Ion [7]
• Burrows-Wheeler Transformation [8]
• BSTW Algorithm [9]
• LS77 [10] or LZSS [11]

Other Algorithms

• ShellSort [12]
• HeapSort

Abandoned Projects

Harry Potter game

Game where the main character is unknown (the main char is not Harry Potter) and you must decide to fight for the forces of good or to side with Voldemort.

SysHook

hook chaining manager
