What do you need?
1) A Solder Station (not the one for electronic school, they use very high temperature). This have variable temperature, from 15W, solder pcb, to 50W, unsolder industrial components (c64 power button and connector). A Solder Iron 15W or 30W will be good too, but for desoldering industrial tip you must have more patience.
2) A good Fan to use during soldering and unsoldering, to prevent vapour's tin inalation. I've made one with a broken computer Fan connected to a 9V PSU.
3) Some good Tin's wire (not the one for electronic school).
4) A little Grab and a Cutter.
5) A Multimeter, analog or electronic (this last one is quite difficult tu use but most accurate).
6) One unsolder Air Pump and one Solder Wick.
7) Some meters of telefon copper's cable. I use it for bridges on vectorboard circuit, but you can use normal electrical cable, for J pins to J pins module interconnections flexibe Ribbon Cable should be used.
..and lot of space on your desk.. not like mine :)
Buy a C64.
Find it on ebay: here in italy prices are too high, but sometimes you can find some Commodore in not so good condition at 10 15 €. I know a guy that can sell you some Sid Chips for less money, if you are interested contact me @ email
Unplug the SID.
Push with a finger on the chip to prevent jumping out and deforming its last 2 foots during this operation.
Prepare to spend some money.
Dowload this PDF CORE SID PSU MIDI Wiring and relative Order List CORE SID and print it.
Now you can exclude all parts you don't need from Core schematic and correct your order list. 
I've excluded jumpers, j5 j6 j7 j11 connectors and 7805 too because i'll use the c64 original PSU. Later we will see how to realize power circuit for Sid and Core.
This is my order list, include parts for Power circuit too: CoreSidList.
P.s. No BankSticks and No mbhp_burner are included for now!
Buying components.
While i was waiting for the kits from SmashTV i bought some parts for 1 Core+Sid to test Sids and arranging parts on vectorboard and my soldering skill too. I bought it in some Electronic Shop here in Rome.. DON'T YOU DO IT! Buy all parts on the Web, is really cheaper. Ex: only these stupid sockets + 1 Crystal 10MHz are about 6,80€.
For all the other parts, in a Shop in Rome, i've paid about 40€ but pay attention! They're without PIC18F452 (i've ordered a sample from microchip for free), 1 Crystal 10MHz, 2 Stryroflex Cap, 2 Midi Sockets, 2 74HC595, 1 6N138 Opto, this two last components here are very hard to find. Considering all the parts that i didn't find, the final price will be so higher!
!! I suggest you to buy 2 or more Vectorboards now, so once you have palced all components over one and you are shure that this will the final circuit relese, you can take the components one by one from it and sold them on new Vectorboard in same position of the first one, without leave all them out !!
Arranging parts on Vectorboard.
To make it easier, i've underlined all Ground in blue, and +5v in red, so the power situation could be more clear. I've also highlighted and grouped the PIC foots to understand where they are go. 
This work, for a first time project, is the most important thing to me for planning the future positioning of the parts.
Assembling Elements.
Good. Now take a food box in polystyrene, or something similar to place the Board over, so you can put the elements on it.
The funniest moment starts now: organizing the Vector Board!
Unsolder Power button and Power connector from c64 motherboard.
I will jump the Assembling Elements for now, because i'm waiting for some other parts. For real, this is not a problem because i've the sockets to use instead of the chips, but if you would place all elements on 1 Vb, you need to unsolder c64 Power parts first.
1) Open your window. You must have some air around you to prevent tin's vapour inalation.
2) Power On your Fan and place it near the c64 motherboard's Power Connector.
3) Power On you Solder Iron and if you have a Station make up near the MAX, 35-40W.
4) Wait until the Iron is Hot. Waiting for this you can see some photos under.
Now you can unsolder all terminals that i've highlighted in red, see photo 05. Position your Iron and you air pump near the solder, in 2-3 second the tin will be liquid. Take off the iron and approach the pump as clos as possible with an 75° angle, not 90°, than push the button that active it. If you use the pump perpendicuar with the PCB (90°) many times the air not enter in the pump, than the solder not came up.
Here there is a photo with some good and bad desolder.
If you make a good desolder, you will see the hole around the pin of the component. Many times unfortunately, a little veil of tin remain inside the hole, because of the force of gravity, the liquid tin go down the hole itself.
Now you can push the terminal with a screwdriver in all direction until the you see that the terminal is lose from the hole.
Vector Board assembling test.
Board Relese 03
After some days of changeing elements position i decide to realize the circuit on one Vectorboard, with power caps of Core and Sid over itself. I've finally found in a shop some small 2200uf caps 16V (first i had some bigger 35V). Very big help was from this links: Core Gif Sid Gif Der Brat 50 of the Big Seppoman, first see than learn!
R6 1.2KOhm of core is lost, don't know when, where, how.. I must buy another one.
I've reserved some space to the right for a Din, not enought but i will arrange.
I've preferred don't leave out connection pins cable from Core to Sid for semplicity (less bridge) and for Din and Dout in the case i will use more Ctrl in the future.
Midi In and Out, c64 Power button and plug will be out of VB, audio plug too.
At last i need to bridge all connections and this will be the next argument. As i had tell, i'll use some copper's telephone cable in 3 colors, Red +5, Blue Ground, White all other Bridges.
The 2 Pins for bridge's Power connection between 5V DC and 9V DC aren't placed yet, i'll do soon, it will provide 14V DC converted to 12V, or 9V by 7812 or 7809 like in Optimized PSU. 7805 of Core module is left out and pin 1 and pin 3 are shorted, because of the 5V DC of c64 PSU.
Explain of PSU
First of all, i want utilize the c64 PSU. Second, i will realize the Optimized PSU from TK. In this case C64 PSU provide 5V DC, perfect for Core and Sid, and 9V AC, that rectified to 9V DC and linked with 5V DC we will have 14V DC, than converted to 12V DC for MOS6581 or 9V DC for MOS8589R5 later.
The two powers must be connected like this: 5V to Core J2 and Sid J2, 14V to Sid J1.
Since 5V must be connected to Core J2 (and not J1) like optimized PDF explain, we will asume that all caps and rectifier between J2 and J1 of Core can left out, BUT TK have suggested me not leave out, so i've leave it on my Psu dsign.
J1 and J2 of Core and Sid are obiviusly not palced because i've palced all Caps and Voltage Regulatos one near one, so i'll sold them without need of J pins connections.
PIC18F452-I/P
Finally i've recived free samples from Microchip, 3 PIC18F452-I/P and 3 PIC18F4620-I/P for future MBSID V2. You can order 3 items per type, and don't forget to order BankStiks too, 24LC256 or 24LC512 I/P as always.
Wire wire wire..
If you don't want to use a Cad software for Pcb like Eagle or others, and assume that you have just placed all components (we will learn 'how to' soon), you can use a simple image editor using different colors for different Wires. Green for Solder, Red +5, Blue Ground, White for Top bridges, BlueSky for Bottom bridges etc. Here there is an example maked with Photoshop, is not so accurate and many connection can be do in different way and better, but this is just the first test i've do. Enjoy it.
Note that Power Wires, blue and red, can be Bridge on Top or Bottom, and can be just Solder too, i will decide laiter if there will some obstacle.
Wire example:
This is an example on how i use Telephon Copper's Cable for bridges. This circuit is a phono Riaa amplifier.
Arranging parts on Vectorboard Step 2.
I'll try to expalin 'how to' how much simple as i can.
1) You must study where all parts are connected on the PDFs and understand wich one you can put colse to the chips, Sid and Pic.
2) Put on the Vectorboard the Core and Sid sockets not too close, for now is not important we will adgiust the distance later, and Pins Cable Connectors.
3) Once you have understand where Capacitors, Resistor and Transistor must connected with the chips terminals and between themself too, you can start positioning. You must do many tests if this is the first time you build a circuit.
4) Start first with the Core and when you think that all parts are qiute in the right place, continue with the Sid.
I can tell you just some suggestions, first because i'm not an expert, second because there are many ways to do the same circuit.
Suggestions:
1) Put the Pin Cable Connectos (Jx) as direct as you can to the respective Pic Terminals, so you can solder it without bridges, you can't do this always obiviusly because of the space.
2) You can put Core J11 J12 and Sid J2 where you like because they have pin in common with Pic and Chip on both side, i prefer close down the sockets itself.
3) The Optocoupler is connectet to just 1 Pic Terminal, RX Pin #26, so you can put where you like, near the Midi In e Out too.
4) If you haven't plane to use J5 AIN (Analog Input) you can place the Eprom Socket (or Pin connectors) near the Pic, with the head oriented to the left (see photos), so you can sold it directly to the Pic Terminal #6, and with a Bottom Bridge to the terminal #28. In this position the +5V and Ground for the Eprom are just oriented external.
5) The Oscillator for the Pic can be put Close to the Pic too if you have leave out J6 J7, and Resistors R9 R10 can directly connected to Pic.
6) P1 and P2 Trimpot for Lcd Luminance and Contrast can be organized in many ways. Sice they have 1 Terminal in common, +5V, and P2 must connected to J15 Vd, +5V too, i've placed this Terminals in same line directly soldered to J15 Vd. Than Pin #2 of P2 can directly soldered to J15 V0, and Pin #2 and #3 of P1 are connected together, than soldered to R4, than to T1b, and T1c directly to J15 B-. (..hard to expalane)
DIN
I've buy the other parts to implement a Din (Digital Input) for upgrade my Sid with Lcd Buttons and 1 Encoder.
This is just first Din test, i'm not so happy of this solution, i will change something..
Murphie's Low
When you think that all is in the right place.. you realize that more space at Sid J2 is needed!
If you see at Sid J2, i must connect 4 Bridges at the Pin Rc and Sc to the IC2 and IC3 74HC595. So i need at least 2 free hole for Top (white) and Bottom (bluesky) bridges.
To do this, i've change the Psu Capacitors/VRegulator system. I've excanged 12V (or 9V) with the 5V, that is shorter. In this way i can place at the Top of Vectorboard the Din and move Sid 1 hole in Up direction. I've place all Sid parts 1 hole to the left too.
Now the problem is that Trimpots are very close to Sid Filter's Cap so i've palceed in the free space near the Top of them.
Pay attention to the Trimpots connection schematic. If you see at the Tk or SmashTv PCB the connections are different. In that PCB P1 term3 and term2 (that are shorted, solder together) are connected to P2 term1 (+5V) and not to R4, than P1 term1 is solder to R4 instead. In the schematic PDF is the opposite, P1 term2 and term3 are connected to R4, and P1 term1 is connected to P2 term1, (+5V). Don't panik, "from the electrical point of view, the behaviour is identical. Sometimes
such changes are just made for an easier layout" TK's wisdom.
Final Board Rlese .05
I think this is the last and better solution for now.
Please note that the DIN circuit is not right in one resistor position and socket direction.
