Pictures of my Commodore C64s

Commodore 64 number 417895

I bought my Commodore 64 sometime in 1988, after a friend bought one. Before that, I had only had brief experiences with Commodore machines with a VIC-20 that my father borrowed home from work at one instant, and machines belonging to a few friends of mine, the computers that I mainly had worked with were Sinclair ZX81 and Luxor ABC80.

This one has serial number 417895 and was manufactured in West Germany, and is marked with "1. März 1988" (March 1st, 1988) on the inner bottom of the plastic case.

I have added JiffyDOS to my machine, but other than that, it is unmodified. The labels that are attached around the F keys lists the shortcuts provided by The Final Cartridge III and JiffyDOS, respectively.

Commodore 64 number 9739

I took care of this computer after my father passed away in 2013. I do not know where he got it from, but I guess he got it from an acquaintance to fix, since it was broken. It has serial number 009739 and is manufactured in West Germany. I had not tested it until I took it out in 2025 and connected it, when I was greeted by the following error message:

I thought that there perhaps was not that much to do, and was considering removing the SID chip, but then the machine has Swedish characters, which my other Commodore 64 does not. I managed to run a diagnostics software from a cartridge, and it indicated that it was just a memory error, and encouraged by other enthusiasts on Mastodon I ordered some memory chips on eBay, and while waiting for that, also a cartridge module that as capable of running a more advanced memory test:

This memory test pointed me towards the same memory module as the first, and it was also the only one that was not the same brand as the others on the motherboard, which indicates that the chips had already been switched once. We replaced the chip, and after that the machine works as expected. So now I have two Commodore 64s, a later module with the small motherboard and an 8580 SID, and an older model with the large motherboard, Swedish characters and a 6581 SID.

It is an official Swedish Commodore 64, even if the modification consists of EPROMs (325017-02 och 325018-02 are Commodore's article numbers) and the keyboard has stickers with the Swedish characters:
