Linux is an open-source, UNIX-like, operating system. It was created by Linus Torvalds and first released in 1991.

It has a broad range of use-cases starting from embedded systems in control and communication or as simple desktop systems, in compact mobile telecommunication over to typical web and application server or even in larger installations like high performance cluster with thousands of nodes.

Linux has been ported to a great variety of hardware platforms since its initial availability for the x86 architecture.

Linux and the C64/128

Emulators

General

• VICE emulates C64, C128, PET, VC20 and Plus/4
• plus4emu emulates the Plus/4
• yapeSDL: Open source version of yape (Freeware-Plus/4-Emulator for Windows), has not been updated for years
  • the continuously refined Windows version is supposed to work sufficiently on x86/x86_64 Linux systems under Wine

Runtime Environments

• cbmbasic: Reimplementation of BASIC 2.0

Emulator Frontends

• jGameBase is a frontend for Gamebase64. The range of the functionality is the as the windows version.

SID Player

• libsidplay: Programm library to emulate the SID, and based on that:
  • sidplay / sidplay2: Commandline player for SID Files
  • xsidplay / xsidplay2: Graphical-Play for SID-Files
  • audacious: A Mediaplayer camparable to WinAmp, that can play SID files through a standard plugin
  • a sidplay-Plugin for the Multimedia-Framework gstreamer exists, so that SID-files can be used by gstreamer-applications like Totem or Rhythmbox
• libsidplayfp: Overworked program library to emulate the SID, can also work with ReSID/SIDv3-Standard (concerning Stereo-SID- and Digi-Emulation), based on that:
  • sidplayfp: Command line player for SID-Files
  • no plugin for gstreamer available yet!
• jsidplay2: SID-Player based on Java, can play all SID files

Editing Disk-Images

• DiskImagery64 can edit D64-Images, insert single files into the disc images and extract those again etc.
• the Midnight Commander (mc) can edit D64/D71/D81-Images from Version 4.7 on, you need the service program c1541 for that, which is part of VICE
  • for mc 4.6.x you need a Plugin (not available anymore, see the mc-Bugreport)
• the Star Commander can be run under Linux via Dosemu (compiling of the available Borland-Pascal-Sourcecodes with Free Pascal or GNU Pascal must be tested)
• cbmfs
  • FUSE-Driver, that lets you mount D64/D71/D81/D80/D82-Images as Part of the host filesystem
• cbmconvert
  • Conversion between different Commodore emulator formats (D64, T64, P00, TAP, etc.)

Data Transfer

• for a serial connection via null modem cable Telnet, Kermit and X/Y/ZModem (lrzsz) are available
• 1581- (and theoretically as well FD-2000-)Floppy Discs can be mounted with the mount command or can be read with a PC disc drive and converted into a disc image with the command dd.
• the CMD-HD can be plugged into the external Port of a [[[SCSI]]-Card via the external SCSI-interface. Backup of the complete hard disc can be done with dd if=/dev/sdX of=image.dhd (X has to be set accordingly)
• openCBM:
  • serves as a trigger for the 1541/70/71/81-drives, that are connected to the parallel port of the PC with a XM1541/XA1541/XP1541/XP1571-cabel
  • Softwarepacket containing Linux-Kernel-Modules resp. windows driver for hardware recognition and diverse commandline oriented server programs in the userspace that handle the read/write access to the disc in the drive
  • these service programs can be used with a GUI via the VICE Emulator
• cbmlink
  • With RS-232 or the c2n232-Interface you can remote control Commodore-computers and attached floppy disc drives, meaning you can load, safe and start programs, read and write D64 files from/in discs.
• c2n
  • c2n emulates a Datassette with help of the c2n232-Interface, that allows for the file exchange with the Commodore-computer with the normal datasette commands LOAD and SAVE.

Data Converting

BASIC

• VICE contains petcat that converts the BASIC-Token into BASIC-files in readable default text and the other way around text into basic programs. It supports Commodore BASIC 1.0 to 7.0 and Simons' BASIC and a lot of other formats. Non printable and graphic signs are saved in portable form when converting.
• detox64: Conversion of the BASIC-Token in Standard-Text (only BASIC 2.0)

Graphics

• MultiColor: Working on Multicolor-Graphics in Koala- and Amica Paint-Format
• c64koala2ppm: Conversion of Koala-Images to PPM

Cross Development

Assembler

• ACME: 6502/65C02/65816-Cross-Assembler
• 64tass: 6502/65C02/65816-Cross-Assembler
• xa (xa65): 6502-Cross-Assembler
• atasm: 6502-Cross-Assembler
• as64: 6502-Cross-Assembler

C

• cc65: C-Cross-Compiler

Others

For the development of the LUnix-Operating System the Cross-Development-Tools lupo (Preprocessor), luna (Assembler) and lld (Linker) are available. Also a Small-C-Cross-Compiler (scc6502) was implemented.
