Sorry for the long time not reporting....

The Robot arm and the interface are powered by a ridiculous 7V non stabilised power supply that I don't own nor like. I have found that I can use 9V stabilised instead. So I could use a Enterprise or Spectrum PSU, but I don't want to mix connectors. I also want a powerful one for this project, so I have ordered a Chinese 5Amp PSU.

I have the parallel cable fixed and ready, but I have to inspect better the robot, if it is well mounted.

When I have collected all, first I will test the files found by Werner, he said that they were CP/M(ISDOS) commands.  

Then I will start doing Basic+Machine-Code tests.

At last I have received the Chinese PSU, so it is time to move.

I have checked the robot arm thoroughly. Now I can say that all is correctly mounted and complete, not so easy as it seems, hundred of little parts, and the instruction book poorly detailed on some steps.

But I can also say that it has never worked. All the effort and caution put on the assembly by the owner was not hold on the wiring phase. As a result, some of the leads are shorter than needed, directed through the wrong hole, or connected on  the incorrect motor, sensor or switch.

Then, I have had a nice afternoon fixing the jungle of leads, at the end not so difficult, but I can understand the frustration of accomplishing the task without some knowledge.

Next, I have tried to feed the 4 motors with the PSU, first to one side and then to the other inverting the polarity, perfect.

One minor problem has appeared when I have feed correctly the robot arm with the PSU trough the FischerTechnick interface: one of the motor driver chips on the interface is stuck and one of the motors is always turning. This is unusual because I still have not connected the EP to the set.

I have checked the components near the motor driver chip and I have found a burned diode. I have de-soldered the component and this is a picture of the zone:

I don't have components at my house, so more on Monday.

I hope the IC is not damaged too, it might be difficult to get a new one.

I was interested to see what that IC does, but I could not find any information.

But then I discovered the part number is TLE4201S1, not TLE420ISI as it looks (ie. one-sss-one at the end.)

So now that I have found it, I might as well post the datasheet here in case you do not have it. On page 554 (:lol: it starts at page 551 :lol:) there is an example circuit with four diodes...

It is a motor driver. I think it is not damaged. I am going to substitute all 16 diodes, because almost all have bad aspect.

Good news!

It seems that the interface works, but I have to  investigate more.

I have loaded the Teach.com app(from the Werner files) on IS-DOS, and this screen appears:

[ Guests cannot view attachments ]

I can understand more or less because the menu is mid English mid German. So I have pressed T, and this is what has happened!

I have switched off all after this attempt, because I still don't know if the rotation of the motors is on the correct gender, or if the numerous switches and sensors are correctly wired. But I think it is a very good start.

Edit: the program has a lot of sub-menus. I will try to translate it to English with an Hex editor.

Sadly, only one Driver chip works, so I have localised and order some of them in China.

It is cool!
Anyway, English and German? The word "modus" seems Latin. (Just a joke.)

The Chinese chips will slowly arriving, so meanwhile I will try Turbo Pascal on IS-DOS, luckily we have the corrupted .PAS source and a .BAK.

Yes, curiously the German language maintains the verb as the last word on a sentence, just like the goodly spoken English.

They've kept the menu initials in English, apparently.

It is (from top to bottom)

"Teach", "Run", "Save", "Load", "Home", "End"

Yes, probably they have translated from English.

Maybe we all together can make a better translation, I have put here the German text:

Just one correction:

Replace "Zange" and "Greifzange" with "Greifer"

And propose to change "R", "S", "L" with "Gelerntes Programm ausführen"/"abspeichern"/"laden"

Thanks, but.... I intend to translate it all to English. I can maintain a fixed German version in case somebody more wants to play with the FischerTechnik interface.

My final objective is to do the Basic+MC version, that will be more usable than this program.

So I have pressed T, and this is what has happened!
It is simply amazing! Something that we have never seen, now over decades and over many country borders starts working again! :smt038
