Project Nixdorf M20 – cleaning the iron 2024

And right now, with a full power, it is going an excellent summer. And I continue to restore old computer. With a name Nixdorf M20. I suggest, that it is a computer level of 286.

So, in a middle of June I transport all the parts to the country house. Case is plastic, and I transport it too to the country house. And, I continue to clean the metal parts from a rust. So, it happened like this, that case itself and small parts are covered with rather big rust. And to restore a computer. First of all, I need to clean it from the rust.

I start to do this, already, in 2023 year. I try different methods. And, only in summer find some proper way to do it. I use a special instrument for cleaning from a rust.

And, in this summer, already, things starts to go better and faster. And, I start to have ideas, that I can do this. To clean from a rust. And this is most big moment.

And, I can, even to say, that metal case is, already, clean from rust about one side. And, I can to remove more concrete rust in the metal. So, more detail work about some fragments with most intense rust. But it is not a lot of this kind. And go to other side. And, I am doing all of these right now. Also, I clean from rust all the details of the computer itself. It is about metal holders. Connectors. And, I need to wash from a rust plastic case.  And I do this too.

Main thing, that all the things are going. And I have some things to say about. Rust is going away with a special tool. And it is rubbed off. With a rag, and metal brush. This tool - it is a special sourness. Which is need to cover a metal. And depending on mark of this tool. Later, you need to wait about 20-30 min. And, then to rub. You can to put in a water some rag. And to rub too. It is about a technique. It depends on certain rust spot. More concrete into metal rust – metal brush. More big layer of rust – too. And what is more easy - you can easily to do with a little rag. After this special thing.

And this way you need to do a several attempts. Everything is going good. It is even more joy! It is so nice, when there is something that you can do good!

And, by the way, it is still have some moments. So, mainly, metal case is in normal state. And rust eats some places absolutely to the hole. At some parts there are holes out of rust. That’s why, mainly, it is normal. About 90s percent. It is a places, where rust eat all the metal - it is hole, or very light surface of metal. And it is fragile and can tear apart or break apart even because of touch. There is such a moment.

Plastic part of the case – it is everything normal about this. It is just good to rub out of rust, which is inside plastic. Process is going on. It is good to rub and rub, as I can to say!

About the details. It is more harder. Some metal construction parts, grille, connectors are in a hard condition. They are covered with intense rust surface. I, partially, rub them. But, I need to more rub. Some details are very uncomfortable to rub. Or some place a metal part is tearing apart, even this can to happen. Some bracings.

It is some danger about a hard drive and power adapter. Hard drive has a heavy cover of rust. Power adapter too. I can rub it. And will they work – it is a question. Hard drive makes less sense to me. It is in better condition. And I can change it. There is some way. And power adapter. In some places he tears apart during cleaning. And, it still has a heavy rust. So, it is still not the final collapse of construction. And inside it is ok state. But, as my brother told me, we need to see it next.

And most big question it is power adapter. I do not know what to change it with. And there are some possibilities, that I will need to do it. And brother told me, that metal can be increased. But, first it is good to clean the rust as good as I can. And it is rather real process! And I am doing it, from time to time, at the country house! At the excellent summer weather or more refreshing evening time. And, I take on a gas mask! To have defense from a metal dust!

It will be very interesting to continue to restore this interesting computer. And for now – I need to continue to clean from a rust. Process takes its time, I do attempts. I cover metal with tool from a rust. I wait up to 30 min. Then start to rub for some time. And next I do repeat, again and again. So, it takes normal time.

Anyway, it is so nice to be at the country house at summer. And to have such a project. Something like some programmers has their pet project. Pet it is goes after some house animal. As I get it. Such a project for interest. So, I have mine one! And I am right now program with Basic. And I have such retro computer old one as a project! And summer - it is just fine!
