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:

• New VGA controller with new modes and VIC-II sync.
• Tripple buffering mode added for properly displaying IFLI pictures.
• Scale-2x video scaling algorithm added.
• Scanline emulation added.
• In cartridge mode real CIAs registers and interrupts are used (allows use of a modem).
• In cartridge mode real VIC-II registers and interrupts are used (allows use of a lightpen).
• Fixed I/O assignments for FPGA (lower power use).
• Lowlevel SD-card functions now use multiple block reads if possible, which increases linear reading speed by about 40 to 50% (most noticeable on large files, such as REU images)
• BUGFIX: fixed error handling and timeouts of the IEC routines, which makes all related operations more robust.
• BUGFIX: added missing timeouts to SD-card functions.
• Joystick port 1 now also works for navigating the menus.
• BUGFIX: on some C64s pressing shift would result in phantom keypresses (F1/F2) under some conditions.
• NEW: various new VGA modes and other options for the new VGA controller (see manual)
• Improved loading speed of file inside T64 images.
• Improved keyboard handling to make the browser a bit snappier.
• BUGFIX: the size of the character ROM saved by the ROM saver was incorrect.
• BUGFIX: .wav player stops at the end of the file and does not continue playing garbage.
• BUGFIX: files bigger than 2k are displayed correctly by the .txt viewer.
• BUGFIX: when copying files out of a t64 image the resulting file was missing the last two bytes and/or the last block was missing completely.
• BUGFIX: filecopy from/to a IEC device did incorrectly abort after 1 block.
• BUGFIX: filecopy filename character set conversion was broken.
• BUGFIX: AR/RR ROM was not correctly disabled when autostarting programs from the filebrowser with AR/RR enabled as default cartridge.
• NEW: added DOS wedge command (see manual)
• NEW: added load and save commands (see manual)

from Wikipedia:

The Commodore PET (Personal Electronic Transactor) was a home/personal computer produced from 1977 by Commodore International. A top-seller in the Canadian and United States educational markets, it was Commodore’s first full-featured computer, and formed the basis for their entire 8-bit product line.

The PET 2001 was announced at the Winter CES in January 1977 and the first 100 units were shipped later that year in October. However, the PET was back-ordered for months and to ease deliveries, early in 1978 Commodore decided to cancel the 4 kB version.

Although the machine was fairly successful, there were frequent complaints about the tiny calculator-like keyboard, often referred to as a “chiclet keyboard” because the keys resembled the gum candy. This was addressed in upgraded “dash N” and “dash B” versions of the 2001, which put the cassette tape recorder outside the case, and included a much larger keyboard with a full stroke motion. Internally a newer motherboard was used, along with an upgrade from static RAM to dynamic RAM and 8, 16, or 32 KB, known as the 2001-N-8, 2001-N-16 or 2001-N-32, respectively.

Sales of the newer machines were strong, and Commodore then introduced the models to Europe. The result was the CBM 3000 series (‘CBM’ standing for Commodore Business Machines), which included the 3008, 3016 and 3032 models. Like the 2001-N-8, the 3008 was quickly dropped.

The final version of what could be thought of as the “classic” PET was the PET 4000 series. This was essentially the later model 2000 series, but with a larger black-and-green monitor and a newer version of Commodore’s BASIC programming language.

Commodore tried to update the PET line with a new redesign called the CBM-II series (also known as the B series). These were not as successful and were ultimately abandoned. However, due to demand, the original PET machines were revived and the CBM-II case style was retained. These were known as the SK’s (due to the separated keyboard). They also had a swivel monitor. Originally, standard 8032 boards were retrofitted into these cases. Later the SK models got a new mainboard that already included the 64 kB extension directly on the board and were sold as 8296 or, with a built-in 8250 dual disk drive, as 8296-D.

This is a new ZoomFloppy package v2.0 that include a new release of OpenCBM and the ZoomFloppy Firmware v0.7.

Here are the changes in the v2.0 version:

• Many improvements and bugfixes.
• Add support for IEEE-488 drives. Implemented by Thomas Winkler.
• Add experimental support for 1571 serial nibbling via the SRQ protocol. Now you don’t need a parallel cable with a 1571. Implemented by Arnd Menge.
• Add support for low-level drive analysis with a 1541 index-hole sensor. This works only on drives with a parallel port and nibtools.
• Bugfix: cbmcopy -r or cbmread now no longer hangs at the end of a transfer.
• Bugfix: don’t reset the bus twice if previous command was interrupted and this command is “cbmctrl reset”.
• Bugfix: increase reset time to 100 ms to be sure all drives are reset.
• Linux build fix for more modern kernels.

This printer was surely an inexpensive ploy on consumers. Out of the box, you got a slow dot-matrix printer that did not have true decenders, and did not have the standard tractor-feed mechanism for using the printer paper of its day.

For an additional price, you could get: a ROM with true-decenders and the tractor-feed mechanism.

The MPS 1270 was the first ink jet printer Commodore released, as part of its MPS series. The MPS 1270A had both a Centronics port and a serial bus port. This allowed it to be used by a Commodore computer ( C64 , C128 , etc.) as well as a PC or Amiga.

Note:

• HP 51604A Ink Cartridge are compatible with this printer.
• The power connector have the TIP Negative and the outer Positive (9v 1A)

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.

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.

The support of the IEEE-488 protocol (thanks to Tommy Winkler) is officially part of OpenCBM distibution.

You can find newest source code for ZoomFloppy in the Opencbm GIT repository.

• CBMCOPY.
• D64COPY for 4040 (thanks to TNT) and 2031.
• D82COPY for 8050, 8250 and SFD-1001.
