C64 C - new look with old board

Ever wondered how to identify the inside of a C64 by just looking at it from the outside?
I can highly recommend Ilesj's article to start with because it gives you nice examples with photos and explains the differences well.

I recently get my hands on a C64 C, it looks nice from outside, has just slight yellowing. Keys are stiff, on/off switch isn't lose so I was sure it will just simply work when turned on.

Oh yeah, it did! Nice red LED, old-style keys, C64 C is written on the back. I quickly loaded my favorite test track (Jammer - Club Style) to hear how the SID sings.

I immediately realized it's a 6581 because of the filtered sounds and the fact the track is kinda broken. I also made a guess that it's a 6581 R4.

Hint: read my previous articles about comparing different SID revisions, search for "C64 SID shootout" in this blog. Cheers.

Opened the case, removed the shiny alu-cover aaaaaand...!

It's an "old" board, Assy No. 250466. Youngest of the old boards. And have a closer look on the SID:

It's a 6581 R4AR aka. R4 Advanced Resonance. My guess was close enough, right?

Back from holidays with a new post

After a very exciting but also exhausting summer time the Kompjut0r blog returns with new posts. I had the chance to take a photo of my current collection and would like to share it. I'm not going to fight for "The Biggest Obsolete Computer Collection" title, it's just a bit of bragging about my stuff because I'm proud of it.

Most of them are in good condition just need cleaning inside and out, but still need to test a few of the C64's since they are newcomers and I never switched them on.

ps: I'm looking for a bigger flat and a huge shelf to store all this stuff
