This is a complex machine with many different systems, and I have done my best to represent it comprehensively. But because of age, the machine as-is. Please bear this in mind when purchasing, there was some previous misunderstanding about this matter.
This machine was well cleaned, but because I didn't do a complete disassembly, I wasn't able to get to all the spots including some of the grill work, nevertheless it is mostly clean, but does have various blemishes expected from age and wear.
The internals appear to be in good condition, and I did not see anything that needed attention or note.
Also:

• I did not service the disk drive. Nevertheless, it passes the performance test and is superficially operating correctly.
• All diagnostics appear to be passing - the errors reported here are expected when the harnesses are not fully connected. As best I can tell, everything "C64" is OK including sound. It is possible one of the joystick ports is not 100%, but I can't say for sure.
• CRT operating, although takes a while to warm up. I also used an external 1702 for this testing (obviously not included)

On the downside:

• The former owner did a haphazard disassembly, and many screws are not present or correct. I have replaced some, enough to hold the case together, but I prefer to not force inappropriate size screws where they do not belong. Be aware of this when handling.
• Likewise, one of the hinge mechanisms and shoulder screws is missing.
• The keyboard is all present, apart from one of the side supports for the space bar. I have fitted a brand new membrane, but not 100% of the keys are working (space and shift for example), so it will need some adjustment. It's possible the wires are loose to the connector as well. I did remove and wash all the keys.
• Note that the bag of parts pictures shows loose keys, these have since been fitted.

Carefully packed for shipping or local pickup welcome.
