Browsing patents today and found the iconic #Commodore 1520 plotter from 1983 has a design patent, awarded to Ira Velinksy (who also did the Plus/4). I arranged the illustrations into a page and of course I plotted it ☺️ 11”x17” with 0.25mm pen on vintage HP 7550+.

"Invaders" is a Commodore 64 Space Shooter game made in Basic for the BASIC 10 Liner Contest 2023. Hope that You will enjoy this one :)

Following @mos_8502's suggestion, I got a tiny MAX3232 breakout board with capacitors already built in and I made my tiny adapter to bring RS232 levels between the Orao and the ImageWriter II printer close enough that they can speak to each other. Power is delivered via USB.

Now I just need to make a nice case for it.

Bacchus/FLT drops another great video on #c64 democoding.

He clearly explains how interrupts work, how to do a scrolltext, and how to move sprites around.

I put together a guide for c64 assembly coding to help others know where to start..

Hopefully useful to someone out there..

Hey Makers! I will say this again.

It's okay if you don't finish a project.

Did you learn something along the way?
Did you have fun?
Did you enjoy yourself?

Hopefully you got *something* out of it.

The journey *can* be the reward...

You can lose interest, you can get stuck, you can put things aside.

Don't feel bad about it.

Get rid of any bad feelings you have about unfinished projects, because we've all got 'em.

And that's okay.

Crazy!

Another piece in the puzzle arrived from @Protovision today.
It's the ARMSID replacement for the MOS6581 and MOS8580 SID chip.
This specimen is of the ARM2SID variety for dual SID configurations.

Progress on my democoding skillz seems to be moving in a forwardly direction...

Just repaired this #Plus4 keyboard, and wow was that a pain! The ribbon needed repairs which took a hour or two, and it was a challenge to keep all the springs and contacts in to reassemble... But they all pass!🥳

I made a video of my learning C64 demo coding and interrupt handling
