I'm trying to figure out how many people would be interested in buying a blank pcb for the Eagle system developed by Georg Braun (http://www.gb97816.homepage.t-online.de/)
We'll need to have an idea of the number of people interested before it is possible to get accurate price offers for the board.

I have posted an identical thread at EAB... please only show your interest in one thread

EDIT: I have contacted a company (recommended by Zetr0 at EAB)... we'll see what they have to say . I myself hope for a price in the range of 2-300 us$

I'm sure whatever manufacturer will let you know a price per board for certain levels of volume.

Depending on price, I am interested.
I may have to buy the English Guru Book first if it gets released.

Depending on price, I may be interested.
Also, you may want to get at least 3 quotes on the blank pcbs.

What's a blank PCB? Do you have to provide your own IC sockets and solder yourself? Is there a ready source for all of the parts required (aside for the Amiga custom chips?)

[Kristian95]

A blank pcb is the mainboard minus all chips and components. If you look at the page of the creator of the board you can download a list of components needed (along a more info on the whole thing) it's in German but all non Amiga custom chips he found in German electronics stores (stores and parts numbers are in the excel file) so I'd say the parts should be available pretty much everywhere. As for the custom chips, you'd need to find someone who has them in stock or source them from a (broken) Amiga (preferably 500+ or 3000).

@jkonstan:

I'll see what I can do getting quotes, alas I am new to all this so I don't really know any stores / suppliers, so if you can recommend any I'll ask them
I'm sort of the "getting things going" guy

[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.

$106 per board is, well, where do I Paypal tonight??!!

I'm super hyped, haven't soldered anything this big together ever, would love the challenge, plus I have the 3000 laying around-and here's the kicker: It would be cheaper to make this board than to buy the 16MB fast RAM for the 3000, almost!!

Who is the treasurer on this thing? I've even got an A1000 lying around that would be perfect for this :-)

As an aside, 030 cpu chips are cheap and plentiful at the local recycling place, just find an old Mac that has 'em. Or there's always eBay.

[countzero]

if it's 106$ per board I'm in too... but you should find a place which will provide and program other programmable chips, the PALs/GALs and there's a lattice chip in there too I guess ...

[Jeff]

I'm in if the price comes in around $100.00. Someone should contact Georg first about the latest revision board files. There have been some recent changes.

Good Luck!

Not interested in a blank to be honest, but a fully populated one, even more if its in ATX form.

[jkonstan]

I had some MiniMig1.1 pcbs fabbed by PCBEX. http://www.pcbex.com/
PCBEX has pretty good prices on prototype PCBs.

Also, you will need to check to if there is a PCB stackup for the A1000 replacement PCB.

I've written comment for Georg in the thread at A1k.org (I speak some German), hopefully he'll help us out
Also, I hope someone can verify that I put the correct parameters... the minimum distance one for instance, if that is to be smaller the pcb will be up to 3 times more expensive....

In ATX form??? What is the point of getting an A3000 like spec Amiga mobo that was developed to fit in the original A1000 case and redesign it to fit in an ATX case? If you are going to redesign it to fit the ATX case, you might as well also redesign it to use an 060 and/or G3/G4!

I don't get it?
