C64 Modding: LEDs / Switches

Hello All,

Not sure if this has been discussed here before, but can anyone provide circuit diagrams or connection diagrams for hardware mods like LEDs and/or switches.

Some stuff i can think of is displaying ZP$01 / VIC bank / drive reset / c64 reset / pause processor / data activity led for drive or serial channel / change(or ground) color bits...

I used to have few of these circuit/connection diagrams but they are lost somewhere.
Some of the stuff above is really easy to do, but is there a collected documentation of the stuff anywhere, feels unnecessary to invent the wheel again ?

Regards
Jani

Interesting! The device is called "Datel Clonemaster." It is shaped like a "Y", and the idea is that you connect two datasettes to it, while the other side sits in the C2N port. Then you can supposedly make 1:1 copies of original games.

It's equipped with a LED, a resistor and a chip named "SP8812 DM74LSO4N". Hmm, some hardware guru might be able to shed light on this. :)

Sorry to revive this old thread, but here is a link of some mods I did to a recently aquired C64 mobo ;-)

nice! Where are you located in Greece. Just got back from Pireus for job reasons and I was wondering if there was any retro activity going on there. By the way I found an Aneroussis joystick in great conditions set by the side of a trash container: I was so happy!

Thanks to all ;-)

@ ready.
Did you find a "Tomahawk" joystick...in a trash bin?? Oh! This was for sure your lucky day!!!
They are heavy duty joysticks, made from arcade parts in a metal frame...practically invulnerable...

I am wondering who the despicable criminal of such a crime is! ;-)

< Off Topic Mode On >
There is lot of retro activity in Greece.
It could be better, but due to the prolonged financial crisis, every cent worths, so we all limited our retro purchases to an absolutely zero....
We have 3-4 major sites about retro computing / gaming and we know quite well each other.
I am located to North Greece (Chalkidiki area - Polygyros).
Here are some usefull links:

The site that I am an editor (and admin)...

(Here is a link to Algo's interview ;-) http://www.iamretro.gr/introducing-algorithm/ )

A very friendly site, from my pals in Athens...

Our local "RetroClub", we gather every Wednesday ... ;-)

"ComputeRevolution", an exhibition special dedicated to computer revolution and evolution. Most of the exhibits are part of our collections ;-)

the joystick I found is this type:

it was in a cardboard box with several VHS and 3.5 floppies, on the side of a trash container. I had the feeling it is very sturdy.
I could actually feel the crisis in Pireous: on the streets there were people from now and then pushing supermarket carts collecting things from the trash. And I really had the impression that these people have not spent their whole life like that. They had a different look from typical people who had lived their whole life on the sidewalk. So I guess they used to have a normal life, which dramatically changed for the worse at some point not too far back in time.

Oh ! Another great one ! I also have one of these "PACMAN" joysticks !
You can treat it as hard as you please...trust me on this ;-)

About your crisis description now...
I totally agree, I witness such pictures everywhere.Sad but true...it turns me furious against our politicians.
I've lost two of my best friends who passed away recently. Both at my age 46-47...Heart failure...too much stress and frustration...People are dying here !

I do not want to make any further comments on this...let's create with our trusty 64s, shall we ? :)
