My new A4000

[gary2000]

I have no experience using that, but I did plan on using solder wick.

[shaf]

solder wick will work to clean off the Chipquik alloy then swab the board with 99% Isopropyl Alcohol to clean off any sticky residue and let dry for an hour.

[mechy]

Chipquick is basically bismuth,its got a low melting point so heat is not a issue, also it doesn't like to "cling' to the chip so much so cleaning is not an issue.

What's the best way to clean off afterwards?  Solder wick?

Glad you found the IDE trouble and it was a easy fix 
As for the chipquick,big blobs can cling to a hot iron, solder wick for clean up.

Congratulations.

All cleaned up and ready to go into a case, if I find one...

Dang dude, that is sexy. I can imagine the thrill you got when that insert disk screen came up for the first time. Our wives will never understand.

I've got a Acill re-spin and a Chucky 3660 waiting for more parts and, like you, have been building my skills and tools for some time now in anticipation of this project. It seems like sourcing is the most challenging, and expensive, part of these things. Anyone who balks at the prices some of the guys selling new-build A4000 and 3640/60 boards has no clue how much it costs to put these together with all the parts. In these volumes we're sourcing, stuff gets quite expensive.

I assume you saw that idcomp.de is carrying both male and female DB23 PCB through-hole sockets, yeah?

[kirk_m]

Yes, I ordered a set from iComp and installed it last week.  Bought another one to build the a1200 clone while I was at it.

And, agreed, building this cost entirely too much money.  The PCB was $100 alone, passive components were right at $200, the SIMM sockets were $25, the card edge connectors cost $12.  The ports cost about $25 mainly due to the 23 pinned ones.  Then there’s the custom chips... those cost over $170 to obtain.  The CIA chips cost another $60, the delay line, VideoDAC, and the chip RAM cost another $30.  The CPU slot connector was $25, and the onboard CPU I soldered in last week cost me $25.  I added the FPU, which set me back another $20.   GOOD quality solder and flux aren’t cheap either, and if you have to buy any equipment, well, that’s a few hundred more.

@ kirk_m
job well done and remember practice makes perfect!
personally I'm glad I replaced my A4000's battery years ago before it caused any damage and also re-capped it so she's humming along awesome as always! btw, is there any improvement to the original on these new MB's or is it just a new replica?

[Acill]

I cant even begin to tell you all how proud of this guy I am! Well done my friend!!

[kreciu]

This is absolutely amazing.

Can you imagine we are in times that we have new A1200 cases, you keycaps, new motherboards and even new CPU cards and other stuff. I wonder who and when will start selling "100%" new A1200 (with OS3.1.4). Nice . Price ~$2000 .

Ps. I got my  A1200 "mobo", it will take me ~10 years to learn how to and do it... but at least it is nice hobby and looks quite pro .

Thanks for all the soldering tutelage over the last year or so, Acill.

So, 2 weeks ago, I soldered in the onboard 030 CPU in QFP package, then added in the 68882 FPU into the existing socket.  This weekend, I built the replica daughterboard, a free design made my Arananet (Edu Arana), and shared on Github.  I made one mistake an accidentally ordered a DIP-14 IC instead of an SOIC-14 (I didn't pay attention to the package type for this one chip, for some reason, but the other two needed ICs I ordered correctly), so, I had to place another damned order with Mouser to get that last part and a few other items needed for another project.

Well...there is already someone selling the A4000 clone, built up by him...on amibay for over 2K euros.  No CPU card or daughterboard included.

They are pretty much clones of the old ones.   The A1200 clone, the ReAmiga 1200, has improvements, like SVIDEO out and use of a DB-15 VGA connector, built in RATTE monitor switch support and built in kickstart switch.
