This power supply for the REU 1764 is arrived for repair destroyed, the internal transformer was completely extirpated from the pcb.
Kernel JiffyDos Installation and Keyboard Repair for my friend Damiano (manosoft.it). To repair the keyboard you must clean the contacts very well on the pcb.
Working Commodore SX-64 in cluster ;-D
Today a friend has donated to me some nice things. Thanks Damiano (Manosoft).
Things that have been donated:
Commodore 64 in a good working state to use for spare parts.
This is a Commodore SX-64 Keyboard which i will use as spare parts.
I am very happy to have repaired for my friend four PCB Commodore in one and half hour.
The defects are:
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.
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.
Nano SwinSID Prototype by x1541:
This project is based on the microcontroller ATMEGA88PU from Atmel and the emulation code is written by Swinkels.
The prototype of Nano SwindSID is a scaled down version of the Micro SwinSID, so far so good, and here’s my initial impression.
x1541, a user of the forum64.de has made a very nice work, the pcb has the same size of the original SID chip (6581/8580), the components are arranged very well and the entire space of the pcb was used. I can just say to buy it when the Nano SwinSID kit will be available, your money will be spent well.

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.
Finally i had time to finish the enhancements of my Commodore 64, below a brief description of what you see in the photos.

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.
DualSID KIT by Tomi Malinen:
DualSID is a device which allows you to plug in two different SID models to your Commodore 64.
You can set the second SID‘s address to five different memory locations. For more information and price visit the Tomi Malinen homepage

Autopsy:
Today i picked up a Commodore 64c Family Pack Edition with Powersupply / Datasette & Joystick in good working condition. The plastics of the Commodore 64c and Datasette are little yellowed but does not affect the right use.
