Who would be interested in a blank pcb for Georg Braun's new A1000 system (GB A1000)

Unless you happen to like the Retro look, liked the original case design of the A1000 and don't want to wait 6 months to 3 years for someone to redesign the mobo to fit in the case size of your choice.

We have the A1000 design NOW, we have the files to reproduce it, the parts (although not so easy to come by) are available, so the project is viable if you already have the case, or I can have a new one produced at a reasonable cost.

Anything else is a different project and it is encouraging that there are still people interested in doing new projects based on the 20 year old Amiga technology.  Hobbies are fun.

I'm curious now what would you estimate the price of a newly made A1000 case to be ??

RoHS *Shudder* - Well, that is at least with respect to the solder. Bah. Awful stuff. It’s bad enough to flow onto the pins of a TIP120 in mid air, never mind soldering SMD's or through-hole via multiple PCB levels.

Ok, so which of the possibilities that I listed would you recommend??

Don't know yet, and I won't make a guess as I have no idea what the setup costs will be, but the guy is a friend of mine, so it will be less than if I had to take it to someone I don't know.

great project

If the board could be sold completely populated I would pay for one.

@Kristian95:
I've never had any professional PCB's made, so I’m afraid that I can't help you there (Sorry if I diverted the thread a wee bit).
I was just mentioning my own personal experiences with the shenanigans of RoHS related restrictions (Solder anyway) for the benefit of anyone who decides to populate such a *large* board.

Put it this way, we're stockpiling leaded solder over here, just so we've got some reserves for the future years :-D

@whiteb

"Yes, MOST of it looks through hole, but remember, this is Through hole on a MULTI layer board. You have to make sure that you solder *ALL* layers."

don't worry, the layers are already interconnected thanks to metallized throgh hole ...  it would be a bit hard otherwise! ;-)

Count me in. It' be a fun hobby computer to work on...

[techie]

If the price was right I'd go for a new A1000 case  :-)

I would be interested in the Motherboard too if it came populated with all the connectors but as that seems out of scope for this project I'll stick with the new A1000 case  :-)

I have a fully working GB A1000. It´s a great machine and it´s very fast. Great work from Georg.
It is the fastest 030 Turboboard, fastram results with memspeed tool:

read: 32MB/s
write: 48MB/s
copy: 24MB/s

[Kristian95]

since this thread has become a bit intertwined with all sorts on other things than "yes I am interested" replies, please pm me regarding your interest (and the maximum price you are willing to pay for the unpopulated pcb). This is only for an unpopulated pcb, so if you are only interested in it if it is populated, don't pm me unless you have found someone to do the soldering for you

Cool, could you per chance tell me what (if any) of the parameters, I mentioned for the pcb, should be changed prior to production of the pcbs??

[skurk]

I'm in for one too, if the price is $106 per board.  I did some research, and the best price I could come up with was $200+S&H in China.  $106 is awesome.

You'll ship it as a "gift", right? ;-)

[Kristian95]

Ok I have now gotten a few things sorted out by contacting Georg
The following parameters should be correct:

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: 7-8 mil
minimum hole size: 11-12 mil
electrical test: yes
material: Fr4
board thickness: 1.6 mm
finished copper weight: 35um for top, inside and bottom layers
board finish: Gold plated (electroplating) or ENIG (electroless nickel gold)
stencil: none
blind via hole: no
controlled impedance: no
buried via hole: no
controlled dielectric: no

With these parameters the automatic quote from the site is:

Gold Plated (Electroplating):
1 board: $ 648,51
5 boards: $ 196 per pcb
10 boards: $ 124 per pcb

ENIG (Electroless Nickel Gold):
1 board: $ 586,88
5 boards: $ 175 per pcb
10 boards: $ 110 per pcb

I have also sent the blue prints for the board to get a "final" quotation from them, but I think these should be pretty close to what we can expect.

Again, please PM me if you are interested and let me know the maximum price you are willing to pay. The more pcb's we order, the cheaper it'll end up being for all of us

Did you build it yourself?  Did you have to beef up the A1000 PSU?  If you built it yourself, do you have a complete parts list (that I probably missed in this thread)?

[Retro_71]

I would love to have one BUT since my soldering skills arnt that great i cant see myself getting one as much as i really want to... New case and new MB that wouldl be great.... but a dream atm.
