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

this one is a bit full on, but there are some nice features (although it's not a lot of LED/switches) -> http://www.bigmech.com/misc/c64mods
i especially like the SID feedback thingy. |

Anybody know how to solder a data activity LED to the C2N port? :)
I have this cassette copier from Datel which blinks whenever something happen on the port. It's very exciting to watch while cracking tape loaders. ;)
In the 1980s my brother had soldered a speaker inside the datasette, so that you could find unused space by listening to those wonderful data sounds... The schematics probably came from the great 64er magazine. |

An activity led should be doable, i guess a Load-it shows "activity" or mainly signal strength.
Why not post some piccys on the datel copier, perhaps the circuitry can be seen on that one.
Wonder if i dont recall seeing or hearing smth about some custom leds, but due to the phases(?) it needs a small circuit. Not sure, someone with knowledge please enlight..
I also recall an article in the 64er...

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 ;-)

A switchless Jiffy/Dolphin DOS mod - Normal C64 kernal
An IRQ led viewer
A PLA led viewer
...more to come... |

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! |
