Ok kokoon, i took a multimeter master class with an electonics teacher at my school ! So now i know more about it ! ;D And now . . . here comes the next question : I've been studying the optimized PSU schematic, and i can see that at the 5V output, two positive cables come out from the positive pin and two negative cables from the negative pin. That cables are delivered trough the two first pins of the SID module(s) J2, positive and negative and the same for the J2 of the core(s) module. Ok, so the question is : What is the best way to create a output for such that cable madness ? How do you separate cables to ramificate them ? Or, a better question .. how can you ramificate the cables ? ? Maybe sounds stupid, but i don't know, perhaps i can find special cables and a especial output connector to do this job ? Other thing that i've to ask : Can you deliver that tension trough two cables by the same pin ? Sometimes i think that i don't know to interpret correctly the schematics . . i never seen before two cables coming out from the same pin ! Thanks a lot !

Hi, i'm the guy who created the thread "mounting my fist core module" This message is going to that people who had canibalized a lot of C64 computers and own a lot of C64 PSU's. I need one to continue with my project because my american PSU get fried yesterday. I connect to it an european adaptor and when i'd plugged it to the wall it got fried. So, please this is a calling to the major C64 cannibals who have some PSU to spare. I will pay something for it. Thank you for the help and all the great things that we are doing together. Thanks.

New problem : I don't know how a multimeter works. I need a t00t of using multimeters. I will ask somebody out, and i will post the results then. Thanks to everybody helping !

Can you call multimeter as "tester" as well ? Because you can't measure nothing without feeding it with electricity, right ? I think you mean a tester . . . don't you ? Thanks kokoon.

Ok, i'll test it . . . but the only way to do that is feeding it with the C64 PSU right ? If not, what other way i've got to test the circuit ? I mean . . . how i feed the circuit without a proper PSU ? Thanks kokoon !

Ok, i finally did it ! If it works, i will post a pair of pictures here to make it easyer for electronics n00bs. But i have another question now . . . The C64 PSU it's so heavy ! ! ! It weight it's like 1'5 Kg . . . What is the proper way to feed the MBSID ? How you did it ? Can you build your own light weight 220 to 5Cv - 9Cv transformer ? Thanks as always !

Ok, so i need to receive what i ordered this week, if not . . i need a solution too. Thank you.

Ufffff . . .. ??? I think i can't manage to do this without any kind of instructions . . if somebody help me doing it, i will resume all this progress and make a .html toot, and if the admins want it, i can upload it here. The problem is that i don't know where to put every component over the board ! ! The C64 Power connector have a very fat legs, so i can't plug it in to the breadboard. I am triyng to solder thinner legs to that fat legs of the connector, but, after that . . where i connect the rest ? I need to know where to plug correctly the components to create the PSU ! ! ! I know that i am very n00b but i'm trying to learn and surpass myself every day but i need some help on this... Thank you in advance, uccaps friends.

What you mean with resolute problem ? Are you from Centsible ?

Sorry about the typing, Kokoon ! When i was about to pay at the electronics shop a problem succed with my credit card, and finally i couldn't bought the stuff !! >:( But i'll do it tomorrow and show the results here then. Grrr...

Ok, so i'll do it with that breadboard. I'm going to buy everything i need this evening, i will speak again lartz. Thanks so much cocoon !

Yes, ok ! I talked again to a electronics professor at the college and he explained me how can i do it. The protoboard (or breadboard) helps you testing project circuits before create them definitively on a real board. But , when it is working already, how do you create the final circuit ? Is there a board design for the PSU ? Many thanks for your efforts to teach me, kokoon ! :D

Ok, thank you for the information . . i will try to desolder it just with the solder. UGhhh i can't figure out how to mount the PSU . . . can somebody explain me how can i do it ? Do I need a protoboard ? . . . I don't know how to do this thing ! Thanks.. :-[

Ok, i talked to an electronics professor at my college and now i know what i have to do, but i have 1 question. In this schema, there are two things that you can't buy in a local shop. The C64 LED and the C64 power plug. The LED it's ok, because it's plugged with a connector. But how can i get the powerplug off the main C64 board ? It's soldered and if i don't have a desolder i can't do it, right ? A desolder costs 50 € ! Thanks for answering my questions.

What are you saying ? Ouch ! I'd ordered a SID chip a week ago . . . do they have a phone number ?

I think i don't know how to do that, seriously. . . what can i do man ? I mean, i don't know how to read electrical or electronic maps. I know i can do it, but . . let's see : Is this optimized PSU already inside the commodore 64 ? Or you have to create a new one ? How can i start ? Thanks.

Well, my first core module is ready to be powered and tested, but . . . how can i power it ? .... i'm an electronics n00b and i don't know such as that things. Thanks. .  ??? [ EDIT ] Ok, now it's powered i cutted the head of a laptop power cable, and now the power is running throug the core. But . . i never used a tester before. Could you explain me a little bit what this exactly means and how i have to use the tester to go for it ? IC1:MCLR(1) - IC1:Vss(12) = 5V IC1:Vdd(11) - IC1:Vss(12) = 5V IC1:Vdd(32) - IC1:Vss(31) = 5V IC2(8) - IC2:(5) = 5V I know again that i am a fucking n00b, but . . . thanks. 8)

Ok, sorry for my n00b questions but here's one more : On the core board, the small and medium bridges are soldered on the normal side way, and the large brigde is soldered at the other side ? I will use resistor legs for the small one, and small isolated cable for the medium and the large one. Is that right ? Thank you for the help. ::)

Can you create this as an AU for Logic ? Thank you, this is a great thing.

Ahh ok, so you're logged in here ! What a cool thing ! Ok, so the orange (334) it's a spare, right ? That's cool. Other question i have to ask you, if the bridges/jumpers should be soldered at the bottom side of the board, and if they be soldered with isolated cable. Maybe just the larger one should be soldered with isolated and not the others ? I have to say that your service it's fast and of a good quality, thank you.

Hi to everybody. I am finally mounting my first core module and i have 1 question. The core modules they sent to me, are different to the ones explained at ucapps.de, they have been actualized.

May-be it's an additional by-pass cap needed to help improve the power integrity? If so, why just one is included ? Maybe i don't need two because when the board was updated the way the by.pass caps are going had changed ? Thank you for your help. Other question . . . should i use isolated cable in every jumper/bridge ? Or i can do it just with resistor legs ? Thanks for your help.

So i have to look for a VGA-LDVS converter ? Can you tell me if this stuff is what i am looking for ? Thanks. http://www.spectrah.com/html/prdt_ad1750.htm#5 It have a power adaptor in, so if LDVS it's what the LCS screens have, it means that this is what i am looking for, right ? Thanks. :-X

Can somebody tell me where can i find a cool hardware forum ? I am looking to do things as recycle a laptop LCD screen and transform it in a current VGA connection monitor. But i need people who help doing it, and i can't find nothing related on the net. Thanks. ???

Thank you . . i think i will create a two SID board so . . it was a very good explanation, thanks a lot !

Hi , i want to ask what is the best way to create a SID speaking on power terms. I mean what advantages you got if you build one with 4 SID's instead of one with 2 ? And . . what's the best, use 4 8580 C128, 4 6581, or mixing them ? Thanks. ???
