As I previously wrote I bought from e-bay an "Oric Atmos 48k pour récup".
It didn't work but this was expected. I started to desolder the bigger chips and to test them - all chips are OK!
So I decided to continue the torture (not sure who was the victim me or the motherboard ) and removed everything!
Here is the result:
My first goal is accomplished: to take HiRes pictures of the empty board.
I scanned it with 1200 dpi and now I have both sides in 2x200 MB files (Windows BMP format).
Linear dimensions are preserved, so pictures can be used as template or for reference.
I think it would be helpful to place them somewhere in public (ideas?)
Next I'll re-solder everything back, replacing some ugly looking parts with shiny new components.
Second goal is: to have a "boutique" Oric Atmos (optionally working )
I'll post pictures to show the restoration in progress.

How did you manage to desolder so neatly?

Re: Oric Atmos from scratch
Hello,
You can open an account on mega or put them in a temporary zone (like free...) before people saved them.
They can be stored definitively on oric.org or defence-force i think.

I can host the files on Defence Force, that's not a problem.

Re: Oric Atmos from scratch
surely this could be used as the basis for a modern reproduction of oric MOBO's (perhaps with a switch to disable BASIC or something)?
Re: Oric Atmos from scratch
I uploaded the files to: https://drive.google.com/folderview?id= ... sp=sharing
They should be accessible for everyone (i.e. even without google account). Both files with preview are the JPG's from my fist post,
the other 2 (without preview) are the ~200MB pictures.
Desoldering was made in "old fashion" way - using usual soldering iron and vacuum pump.
Actually the board quality is surprisingly good! I was bit worried about the thin tracks but they endure well the heat.
Else from one moment the task becomes boring but helps for calming down the stress and meditation .

Re: Oric Atmos from scratch
The PCB are quite good quality expect for the soldermask which just crack overtime, but this is a common issue on 80's PCB.iss wrote:I uploaded the files to: https://drive.google.com/folderview?id= ... sp=sharing

Re: Oric Atmos from scratch
Neat job. I have a lot of trouble desoldering neatly. I've just ordered a new soldering iron. Maybe a need a new noozle for my solder sucker?
I find the copper track can lift off. I tried desoldering braid but that made a mess of the board and didn't suck up the solder very well.

Re: Oric Atmos from scratch
I must confess that the idea of making an Oric this way is very, very appealing! What about converting the BMP's to vectors and tracing everything in a viable format ..
Re: Oric Atmos from scratch
I do have a lot of Oric boards sitting around. They have sockets and some chips fitted but could easily be stripped down.
If anyone wants some boards to play with, let me know.
