SID Known is a command line tool (M$ Windows) which you can use to identify SID tunes from SID and PRG files.

This tool can be used if e.g. you want to know which SID tune is used in a specific C64 demo or C64 game, or you have a SID tune found or ripped and you want to know if it is already in your SID collection.

CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 or VIC20 if you’re feeling brave and have the right kit.

CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.

It was also a good opportunity for a face lift and to add some new features, such as:

• Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
• Tabbed MDI.
• Syntax highlighting.

What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.

C64 Studio is a .NET based IDE written by Georg Rottensteiner.

This app supports project based C64 assembly. The internal assembler is using the ACME syntax.

In connection with Vice the IDE allows you to debug through your code and watch variables/memory locations, registers and memory.

Any other emulator can be set up as well if it’s startable via runtime arguments. C64 Studio allows you to compile to raw binary, .prg, .t64 or cartridge format (.bin and .crt for 8k and 16k).

Additionally to this C64 Studio comes with a charset and sprite editor.

Version history:

21.06.2011 – 1.3a:

• Fixed weird exception when using Umlauts at the line end.
• Added tab configuration.
• Added undo/redo to toolbar/menu.
• Autocreate project if new document is created without project.

19.06.2011 – 1.3:

• Added image export for sprites.
• Fixed wrong modified state in sprite editor (selecting single/multi-color chars would set the project as modified)
• Added import/export of all sprites as image.
• Added import/export of all characters as image.
• Added pseudo pc macro.
• Added project configurations with predefines.
• Added element dependencies.
• Enabled sprite/charset files as part of projects.

Turbo Chameleon 64 is an extremely user-friendly cartridge that can be used without opening the computer. It is just plugged to the expansion port of the C64.

The Turbo Chameleon 64 cartridge can also be operated as a stand-alone unit (since it’s basically an FPGA computer like the C-One or the Minimig in a C64 cartridge case), replacing the computer, the floppy drive and the heavy power supply.

When used as a stand-alone unit, a USB power adapter or active USB hub can be used as a power source.

Changelog:

Differences from Beta-5b to Beta-6:

• Fixed RAM mirrors for 1541 drive emulation.

• Implemented disk-change with button.
• Input latch emulation in VIA emulation.
• Implemented SDR register in CIA.
• Implemented real IEC bus disable bit.
• VIC-II timing fixed for mode bits (MCM, BMM and ECM)

Differences from Beta-6 to Beta-6b:

• 1541 emulation: fixed IEC timing. All known speedloader problems are gone now.
• 1541 emulation: VIA6522 timer fixes.
• 1541 emulation: VIA6522 register r/w fixes.
• New cartridge emulations.

Differences from Beta-6b to Beta-6c:

• Auto speed option for turbo feature. Slows down on IEC bus accesses.
• PS/2 Page up/Page down alias for F1, F7. Easier navigation in the File-Browser.

The ZXpand interface is a brand new interface for the Sinclair ZX81, and Timex-Sinclair TS/1000 Home Computers.

The ZXpand interface offers 32K of expanded memory (which is configurable to support various hi-resolution graphics modes), instant file access to .p files stored on SD memory cards and more.

The Sinclair ZX81 ZXpand interface will also allow you to connect an Atari style 9 pin joystick port to play either specially written or specially adapted games.

The ZXpand provides the following facilities:

• SD Memory Card reader – for instant loading from / saving to .p files (used by ZX81 emulators)
• 32K of configurable RAM memory, which can then be set up to use the various hi-resolution graphics schemes for the Sinclair ZX81.
• New keywords are added to the system ROM to allow you to load and save programs, produce a catalogue of files on the memory
  card, configure the ZXpand Interface, and delete files.
• You can still load programs from cassette as well as using the interface, to allow you to copy files onto the SD memory card.
• Sub-directories are supported on the memory card.
• The new ROM can be switched off once a program is loaded, in order to allow access to LPRINT, LLIST and COPY commands.
• There is a built in reset button to reset the ZX81 without having to pull the power lead.

The 1541 Ultimate-II is a peripheral developed for the Commodore 64 (C64) by Gideon Zweijtzer.

It’s a C64 compatible cartridge that carries an Action Replay, The Final Cartridge III, Super Snapshot, Retro Replay or TurboAss with Codenet support (whatever the user prefers) and a fully compatible FPGA-emulated Commodore 1541 floppy drive that is fed from a built-in Mini SD card slot with C64-compatible files (e.g. .D64 diskimages or .PRG single program files).

The difference between 1541 Ultimate-II and other SD-based & .D64 mounting cartridges (like the MMC64, Super Snapshot 2007, or MMC Replay, SD2IEC) is that the 6502 microprocessor that powers the 1541 floppy and the 1541′s mechanical behavior (even sound) is fully emulated, making it theoretically compatible with almost anything.

File selection and management is done via a third button on the cartridge that brings up a new menu on screen.

Note: This is my first printer.

from c64-wiki.com:

The Commodore MPS 801 was a Matrix-Printer (Stylus-Printer) from Commodore released in the year 1984. MPS stands for Matrix Printer System, an invention from Commodore.

The Commodore MPS-801 was one of the first Printers offered by Commodore for its home computers. The printer used fan-fold paper via a paper tractor. The print resolution was a 6×7 Matrix at 10 chars/inch. The printing speed was about 50 chars per second.

Because of its 7-pin print head, character descenders couldn’t be created with the MPS 801. This was later made possible through some software tricks. The printer only supports unidirectional printing (i.e. it is only printing when the print head moves from left to right). On the way back to the left, the print head was inactive, which made the printer very slow, compared to later models. The interface to the computer was a serial IEEE-488, the serial bus for the C64.

The printer was not developed and produced by Commodore. The MPS-801 was produced by the Japanese company Seikosha, a subsidiary of the clock manufacturer Seiko (the same model there was named Seikosha GP 500 VC). At that time, Seikosha was one of the largest printer manufacturers in the world and was also manufacturing printers for Atari, such as the Atari 1029 printer.

Apart from the complete ASCII-charset the 801 could also print all Commodore graphic characters and reverse characters were possible. In addition to text and special glyphs the printer was capable of printing graphics.

For manual paper-handling there was a mechanical handwheel on the right side of the printer. Additionally a membrane key was provided for incremental linefeed.

The HxC Floppy Drive Emulator is a software and hardware system created by jfdn aka Jeff.

The aim of this project is to replace the floppy disk drive by an electronic device emulating the floppy disk drive (list of supported Computer/Hardware).

There are two differents emulators:

• A USB version which allows to connect the floppy disk drive interface of the computer to a PC via a USB cable.
• A SDCARD version which allows to emulate floppy disks which images are stored in a SDCARD.

Release notes for the HxCFloppyEmulator software v1.6.9.0:

• New files Support : Kurzweil KRZ file support.
• New files Support : EDE EDM (Ensoniq Mirage) file image support.
• A new “About” window ;).

Two Commodore 64 added to my collection. The external case was bit dirty, it took me a couple of hours for a good cleaning but now the two C64 are like new.
