I have found a Commodore 64 / 1541 Floppy Drive and a C16 Datassette in the trash.
The Floppy Drive was very dirty but in good working state, while the Commodore 64 was faulty (black screen with tiny raster effect). I have replaced the video chip (MOS 6569) and is back to run better than never.
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.

This is a very old project published in a Dutch magazine to capture the state of the IRQ for Commodore 64 (vic-20) with a LED. After many years i have decided to make it.
On the photo you can see the project and the right connections on the cartridge port.
Components:
How it work?
When the CPU generates an IRQ the green LED lights up, otherwise is red, if the irq is turned on and off quickly the led is orange.

On the Photo you can see the AVR ISP homebrew Adapter for programming the firmware.
Firmware update (10012011):
Hardware tip:
To increase audio quality and volume level replace R4 (2k2) resistor with 1K. This will boost volume by about 50%

Commodore 64 it’s back… and better than ever! The new C64 is a modern functional PC as close to the original in design as humanly possible.
It houses a modern mini-ITX PC motherboard featuring a Dual Core 525 Atom processor and the latest Nvidia Ion2 graphics chipset. It comes in the original taupe brown/beige color, with other colors to follow.

Finally i had time to finish the enhancements of my Commodore 64, below a brief description of what you see in the photos.
Enhancements description:
ZoomFloppy is an USB device for connecting Commodore disk drives to your PC.
The ZoomFloppy is an improvement based on XU1541 from Till Harbaum. Nate Lawson and Jim Brain teamed up to produce a professional product.
This controller will support IEC drives, IEEE-488 drives and a user-port connection for parallel speeder drives.

The team from dienstagstreff.de has demonstrated a Commodore C64 on the “Hobby und Elektronik 2010” in Stuttgart.
Demonstrating a C64 is not so special but this time the C64 was under water! They submersed a C64 circuit-board in water, connected it to a power supply and a monitor and the C64 work without problems for 1 hour.

Autopsy:
Today i picked up two Commodore 64, both are in poor condition and Broken.
The first one with the chip SID 6581 can play a garbled sound and the closing hooks broken, the other one with the chip PLA 906114, 7406, CIA 6526 dead. I made some cleaning and repaired the problems.

Wood, the Portuguese developer who ported the Speccie game ‘Uwol: Quest for Money’ to the C64 is almost done with his conversion of the rather obscure title, Nanako in Classic Japanese Monster Castle.
In this game you control Nanako, the game consists of 25 levels, you have to climb one level to another level in the castle and offcourse, there are some baddies.
Let me spare you the details of the background story, but Nanako … looks like a very original platform game.
