Resurrecting an A2000... the hard way...

[norby]

I've always like the A2000, an A500 with endless expandability....

At some point I aquired a A2000 system with a 6.x board. The board was pretty broken and had been repaired more than once. For a long time I had entertained the idea of remaking the PCB. The broken board seemed like the perfect candidate...

The schematics for the board was done in eagle over the course of 7-8 months. Desoldering the board was also a challenge until I got a new heat gun .

Laying out the board was done by measuring the now completely desoldered board.

Two weeks ago the looks from eagle was something like this:



This was sent to a board house and today this arrived in the mail:





Looking forward to see if this will actually work.

That's quite cool, any plans to have more boards made for others or release the files for others to have boards made themselves?

 

[TheCorfiot]

Very impressed.. I want to build one

 

[cercamon]

Impressive job. Congratulations. And double kudos if the board actually works. That's a new homebrew revolution start for retrocomputing.

If it works, I will be happy to provide boards. I would like to use any (possible) profit generated from this to fund similar projects.

I'm already entertaining the idea of a rev. 7 board, with 2MB Chip RAM (similar to rev 8 A500). Also incorporating all erratas from rev 6.x.

What kind of sorcery is this???
You did an amazing job.

 

[velourfog]

Well done, sir!

 

[gseb]

Cool !

You are the second to do this. A pity, one could have spent time on another cool project.

Hier the first one I knew about this, he's right now populated his motherboard....

Excellent idea, keep up the good work. I have a broken A2000 hopefully I will bring it back to life.

Funny,
I have done exactly the same

Not exactly... yours is red!
Anyway, the two ones are great projects!

gseb pointed me towards your project over at a1k

I wasn't aware of until today... maybe we should compare notes ;-)

My german is a bit limited, but it seems you are discussing somthing about a A2630 ? This was kinda next on my list ... maybe we should join forces?

Yes plaese. I started the A2630 rework last Year. An original Board is disassembled, measured and the redrawring ist in process

Send me am PM

 

[norby]

PM sent

 

[Tuxbar81]

Perhaps a future collaboration! Excellent! ;-)

It's an amazing job.

That is one way of doing it, which I considered for a while, but it seems these DRAM chips are scarce...

Instead I decided to use the existing 4x256K DRAM chips, since I have the luxury of just redoing the PCB



More or less stolen from the A500+ Rev8 and A501+

Now you have the finished PCB design.
It would be easy to change the form factor to ATX and use a PC case

simply awesome , i too have a desire to remanufacture some Amiga boards...
