Jó hír!

Great! we will see two (almost) original game releases on the horizon this year...

If they where programmed on an Ep.... we can say they are originals, can't we?

Yes, probably they have translated from English.

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

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.

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

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:


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.

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.

Not so sad, it seems that the man has his head still on, and it is a very good new.

What is very sad is the behaviour of the great corporations with theirs staffs, treating them like shit when they don't need them anymore.

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.

But....... On SymbiOS the thing changes, there is a HTML viewer that on a future will allow hiper-links, when some SF3 characteristics(WIFI) were being integrated on SymbiOS, but this is a task of Prodatron.

No sorry. The Mouse driver is very basic, it returns you a coordinate if a click is done, so is the task of the program to know what is on the coordinate.

I was unable to integrate the mouse on the Editor due my low assembler skills and to the characteristics of the hack(it is a hack that runs on an interrupt), but at least I managed to allow a mouse channel on a text screen(40,80 all dimensions), where the pointer not slides, it moves to the next character boundary. You can learn how to interact with the mouse system on the EnterMice wiki, but I still have not actualised the link to the last version.

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.

Az összes MIDI érték a 0-127 (7 bit) tartományba esik, bár néha +63 és -64 között van (az első 7 bit komplemense).

A MIDI fájl olyan, mint egy adatfolyam. Fogja az első bájtot, elemzi a benne lévő parancsot, az első 7 bitbe kódolja, majd vegye a következő bájtot, elemzi és így tovább.

Egyes parancsoknak csak 1 bájtra van szükségük, másoknak többre. Ezt a nyolcadik bit jelzi. 1 azt jelenti, hogy a parancsnak legalább 2 bájtja van. Ha a következő fogadott bájt 1 a 7-es bitben, akkor a parancs 3 bájtnál hosszabb.


All MIDI values are in the range 0-127 (7 bits), although sometimes it is between +63 and -64 (Two's complement of the first 7 bits).

A MIDI file is like a stream. You take the first byte, parse the command inside it, encoded in the first 7 bits, then take the next byte, parse it and so on.

Some commands need only 1 byte, others more. This is indicated by the eighth bit. 1 means that the command has at least 2 bytes. If the next received byte is 1 in bit 7, then the command is 3 bytes or longer.


Todos los valores en MIDI están en el rango 0 a 127(7 bits), aunque a veces también indica entre +63 y -64(Complemento a 2 de los 7 primeros bits).

Un fichero MIDI es como un flujo, tomas el primer byte, interpretas el comando que contiene codificado en los 7 primeros bits, entonces tomas el siguiente byte, y así todo el tiempo.

Algunos comandos solo necesitan 1 byte, otros más. Esto se indica en el octavo bit. Un 1 significa que el comando tiene al menos 2 bytes. Si el siguiente byte también tiene un 1 en el octavo bit, significa que el comando tiene 3 bytes o más.
