Commodore 64 Computer Cleaned, And 10, Hours W/ SID, Box, Cables

Tested for over 10 hours (640 iterations) with the Diagnostic Rev. 586220 and full diagnostic harness, without any errors. This Commodore 64 has been cleaned, repaired, and tested. Any malfunctioning parts have been replaced. The keyboard back was removed and all contacts cleaned. The case and keyboard are in excellent condition but do have some minor yellowing (see photos) There are no broken hinges, tabs, or screw mounts. (See Photos) The serial number is P5764409. It has mot...herboard assembly number 250425 with 8-pin video output. It has all the original MOS chips including an original SID. All the original shielding is in place, and it has the later revision metal heat sink shield that works much better to keep all the original chips from overheating. I cleaned the heat sink and chips and added new heat sink compound during reassembly. The computer comes with an original serial number matching box. The box is in fair shape. The graphics and color have some fading and some frayed corners and edges, but considering its cardboard and over 30 years old, it looks surprisingly good. The original foam protection and internal accessory box are also present and in good shape. The serial number tag is very faded and almost impossible to photograph, but I can confirm it's the correct box for this computer. I often buy this just to find out that the box and computer do not match.  Also, included is a basic S-Video cable. I make the video cables myself and the cable is around 5' long. S-video output is about the best quality output you can get from these computers, but if you would prefer a Composite (RCA) cable instead, send me a message after the auction and I can swap the S-Video cable for a Composite cable at no additional charge. I am also including a repaired power supply for free as a courtesy. Since the transformer and AC rails in the original PSU almost never fail, I open the PSU and bypass the failing DC voltage regulator with a new 5v buck converter connected to the diode bridge from the transformer. The buck converter is much more efficient and cooler than the old linear voltage regulator. This buck converter is rated up to 3amp max for short bursts and is stable at 1.5amp, which matches the original output rating. This power supply was used during the  testing of this computer with no issues. I have not had any problems with these, but you use the power supply at your own risk without any guarantee. It is probably safer than most of the original power supplies at this point, but you can also find many quality professionally made new power supplies for sale online. If you do not want the power supply, please let me know. The sticker on this power supply is starting to peel and the plastic on the bottom cracked during disassembly. I've glued the bottom back on and the power supply performs well it's just not the most attractive brick.  The auction does not include the diagnostic software I only included the screenshot of it to show that I have used the full Diagnostic Rev. 586220 with harness to test the computer. I also use Trilogic 64 Doctor to verify that the keyboard and game controllers work.Since I'm listing this with free shipping I will use either USPS or UPS, whichever is cheaper, for shipping. Please feel free to message me if you have any questions.
