Does anyone of the cracks know what these plastic bits are for on the keyboard? 🤦

Today I'd like to complete the red #C64 refurbishment. I already carefully rinsed the case with water. The CPU, SID, and VIC got heatsinks. I bought new screws, so the mainboard is properly fixed to the bottom shell again. Now it's time to clean the keyboard. #retro #retrocomputing

repair plot twist: I FRICKING FITTED THE NEW LOGIC CHIPS IN REVERSE… Deep breaths. 🤦‍♂️🤦‍♂️🤦‍♂️ (On an amusing side note, nobody noticed when I repeatedly posted pictures of the area…)

I’ve been using lots of flux, that’s why it looks a bit messier than it is still. I’m going to clean up properly after some more testing.

repair progress. Added a number of additional bodge wires, triple checked all connections in the battery area, fitted new (nicer) RAM sockets.

(I‘m also going to clean up the flux residue. In this state, it looks even worse than it actually is… 😅)

Moar bodge wires. I think I have all the connections on the ICs fixed up now, still some smaller components to check and rewire. Phew. The adventure is going to continue tomorrow.

Replacing electrolytic capacitorps now, then I’m going to slowly put replacement components in and wire the connections back up that were eaten by Varta. Wish me luck! 🤞

Current status: trying to edit video while construction work is going on in the apartment next to me. I think they are removing floor tiles or something. Feels like they are drilling straight into my forehead. And I can’t hear the audio in my edit at all. 😩

Good Morning, Everyone!

Today's retro pick is the "PET 64" also known as "Educator 64-1" or "CBM 64".

It's basically a Commodore 64 in a PET case.

Rumor has it that the NY state education department demanded a more heavy, solid case for the educational Commodore 64s used in schools as these seemed to "disappear" due to their compact size and light weight. Also, by recycling PET cases, Commodore could present an educational version of the C64 at almost neutral cost.

The Kernal has been modified to display a monochrome, black and white screen as well as displaying all sprites in the color black. This can temporarily be undone by using the following Poke:

POKE646,PEEK(646)OR128

Otherwise the mainboard used is an ASSY 326298, Revision A

Later models of this system used a color monitor but production ceased in spring 1983.

Happy to see all the unboxing pictures of the in the last couple of days. It’s a beautiful machine! One thing though: what’s with that label? Kind of ruins the look in my opinion. Should really be a flat metallic sticker like on the original Commodores. What do you think?
