You can download the Project Files from http://www.gb97816.homepage.t-online.de/
The PCB will not be cheap and some Parts are rare.

P.S. Is that an "I'm going to leak" barrel battery on the new phoenix board?

This is awesome!!! Minor revision on the battery.... but hey what do you want for a wooden nickel?

Now if someone could do something like that for an A500? Come to think of it why would you need an A500 or an A2000? Everything you need is already on the board except maybe a video enhancement card for 24bit video.

Does he take mod requests?

I was joking. Mostly.

It's a shame that PCBs are so expensive - I've had unpleasant surprises trying to get a very simple PCB made, so goodness only knows how much that would be!

[Kristian95]

Does someone here have any idea of what price-range we'd be talking about per pcb if let's say 10 or so were ordered ??
I am sure we can find about that many people interested if the price is right

Not sure what you call "right". The usual price is around 250 Pounds! Only for the mobo, no socketed custom chips.

[Kristian95]

yikes! I was thinking about around 250 us$ for the board... does anyone know some good companies to approach for an offer?

[Zetr0]

@Kristian95

Well you could try this company

http://www.futurlec.com they have a PCB fabrication service, so you might get the basic motherboard pcb quite cheap, then you will have to populate it. that could cost a few quid, BUT i beleive you could get the lot and do it yourself for around £150, mind you if it doesn't work you will only have yourself to fall back on.


however i would be tempted to change some of the things on the board, mainly the memory, (use a 72pin simm for starters) and faster chiprams etc.

[Kristian95]

thanks for the link Zetr0, I'll check it out
I myself am a total beginner at soldering so I'll have to find someone who knows what he/she is doing and persuade the person to help me out (bribe if necessary hehehe)... if I can get the pcb for the 2-300 us$ I'll be fine with the other costs too... after all, I have found out that the A1000 case is about 10 cm too narrow to fit an A1200 motherboard

[DJBase]

You can let produce boards for less than 100€ per piece at a minimum of 10 boards.

[Kristian95]

@DJBase which company is that ?? sounds good!!

[Sune Salminen]

holy s**t what an awesome and crazy project.



There are plenty of other interesting projects on his website too.
I'm digging the tube amp..

Various, mostly in china or taiwan.

@Z:

I think the on-board memory is good enough (albeit expensive): Georg build it with SRAM. Hmm...

Good idea for our accelerator... At least for the EC020 version...

4Mb of SRAM could be not THAT expensive...

Hehehe ok... I'm asking since I know next to nothing about pcb companies and wouldn't know where to start

Easiest way would be to use google and ask for prices.

[Zetr0]

@Kristian

try Futurlec they have a wonderfull service there, ( i have not been let down yet )

they have a PCB manufacturing service, all you do is tell them the number of layers, the width, length and if you want solder masks / silk screen and then you send them an email with the eagle board attached.

I have taken the liberty to find out how much the board would cost to make its not as bad as one initially thinks

Printed Circuit Board Service
	
Step 6: Board Summary

Length: 342.00 mm
Width: 315.00 mm
Area: 107730.00 mm sq
Board Type: Double-Sided
Silk Screen: Yes
Solder Mask: Yes

Printed Circuit Board Quotation
Qty	Description	Each	Total
1	Double-Sided Printed Circuit Boards 	107.73	107.73
1	Silk-Screening for above boards 	12.00	12.00
2	Solder-Mask for above boards 	12.00	24.00
1	Setup and Artwork for above boards 	15.00	15.00
Total (USD)	158.73

obviously the more boards you buy the MUCH cheaper it becomes.

However the above is just half the story, next you have to populate it that will be around another $150USD.

then you gotta build it

oh and dont forget delivery and stock availability as well.

[Kristian95]

I mailed them but forgot the masks / silk part and I also forgot to attach the board schematics *dumb dumb dumb* ups!!
I don't have a proggy to read the board schematics... are the .brd and .sch files from Georg's site the ones I'd need to mail them ??
Btw Zetr0, I'm afraid the board is 4 layers not 2 according to what I heard on Amiga.org

[Kristian95]

I checked out this place: http://www.pcbfabrication.com and the prices are pretty good!
If I figured it out correctly (I am quite sure I did!) the price for 1 board is:

1 board: us$ 360 per board
5 boards: us$ 168 per board
10 boards us$ 106 per board

Does anyone have any experience with this company? Also I'd prefer if someone who knows these things inside out can help check out I did get the right quotation...
Here is what I filled in:

4 layer board
Single board with 1 board per panel
board length: 317 mm
board width: 342 mm
peelable soldermask: both sides
solder mask: 2 sides (blue board)
silkscreen: 2 sides (white)
minimum trace/space: 9-10 mil
minimum hole size: 17-18 mil
electrical test: yes
material: Fr4
board thickness: 1.6 mm
finished copper weight: 35um for top, inside and bottom layers
board finish: hot air solder leveled
stencil: none
blind via hole: no
controlled impedance: no
buried via hole: no
controlled dielectric: no

Please, please let me know if these are all the correct settings... I am only sure about the dimensions and material.

@Kristian95

alas i have not used that service, however I have loaded the board into eagle, and although it is 4 layers, two of the layers (route 2/3) you could re-work with 28AWG wire as theres very little that connects to them.

Infact if i get time (and eagle lets me), i may be able re-work his design for two layers.

if you need tools etc, try here

hope that helps.

to be honest, I believe that it might be worth contacting futurlec to see if they can manufacture this board, as i am sure you can get it manufactured a LOT cheaper than $360USD

[Kristian95]

ah thanks for the advice Zetr0 I'll keep looking into this
