Hardware / Re: Problem RGB - SCART.

Your idea of an adapter for a Scart to Scart cable is brilliant, but for it you need to twist your mind... First time with the 90 degrees contacts( at the green PCB on your picture), you can easily swap the rows. And then the second time with the cable, as the schematic is made for the female Scart connector at the TV side.

I would have made a lot of errors, sure.

And, probably you have used this schematic:

Didn't you?

The sound output on the the RGB port is very weak, you only will hear it optimally with the Volume pumped up to the max, and it will add noise from the TV amplifier. Better take the sound from the Save Tape jack connector, It outputs in Stereo at the correct level!

The estrange and common on your set-up is that the two EP64s produce exactly the same issue WITH THE SAME CABLE, made by you.

Have you discarded a possible error on your cable?( I am the first here that sometimes overly trust on my experience....)

Ah, great. Thanks.

The fact is that the help works without the space on the first commands of the list until F.

I have found an annoying issue on the help messages on the emulator's debugger monitor, page 2.

If you execute "?", a list of the available commands is printed on the screen.

Then, if "?F" is executed, the syntax of the F command is shown.

But I have found that the subsequent commands help doesn't return the syntax, only a ? without more effect.

The G,H, etc commands execution seem to work, but I can't use some of them because a lot of parameters are needed and I can't add their correct position.

Is there some place to consult the syntaxis of these valuable commands?

Hello C5484:

This time I want to order you 2 x JoyCapG1CF190gren: 2000HUF / 6EUR

I don't have any hurry, so better if you join them with the next order.



Programming / Re: Changing the EXOS font

Yes, on a German Ep, the Language Rom is on the cartridge so, on some circumstances the internal font doesn't match the keyboard...

As Zozosoft says, it does contain a new video driver. Because it's a user module and not an extension, the new driver doesn't remain when you leave Basic. It probably wouldn't be too hard to make an extension out of the existing code. I guess they didn't do this originally because it would take away one 16k segment and that would be a problem for the EP64. The interlaced screen already takes up most of the memory.

You are right, the new VIDEO: driver is forced to install on the Basic area so, once the user exits from Basic the system is corrupted and forced to reset. That is annoying, but maybe they done that way because probably the Interlace driver works badly outside the Basic interpreter.

I have always read that an EP64 cant load the Interlace driver. At least on the emulator it crash.

Okay no problem. As long as your "dissatisfaction" with the Enterprise doesn't grow excessively...


I have been always curious with the bad behaviour of the Interlace driver, so I will continue reporting what I found.

I have made a basic listing to decode such relocatable files. It only shows a list of commands and its parameters as a row of bits, later it could be modified easily to save the data on other format, Hex or Raw.

If some of you want to see, for example, the entire 5KB of the Interlace.COM file, better put the emulator to max speed.

The interlaced screen already takes up most of the memory.

Great! I like to take the EP up to its limits.....

I didn't read your last comment, and I am interested.


Ah, great!

So now I am going to decode the relocatable file... with a Basic program.

I did the same long time ago, to study the Mordon Quest game.

I am taking a look to the Interlace file, and it doesn't loads as an extension, but as an user relocatable module(02 type-file)....

So probably I am totally wrong and there is not a VIDEO: driver inside...

Interlace is not new at all, so the content of the file is known since long time.

Then, what you want to do is modify the VIDEO: driver...?

And surgically on the EXOS Rom, like you did with the font....?

I suggest you another way that will be easier and with less handicaps: better modify the Interlace VIDEO: driver.

For some good reasons it will be the west way:

-You will learn how the relocatable code loads on the Enterprise. You always can convert the driver to fixed address for better developing.
-You will learn how an extension loads itself and installs. The same with a driver.
-Maybe you could fix some issues the Interlace mode has, to make it more usable....

Once you have a working driver you can proceed to modify/paste it inside the Rom.

I have tried to use more than 2 colours on text 80 mode, but it has an annoying tendency to jump lines when there is CR or at the end of line. On the middle of the screen the alternate colours work great.

Yes, and Judge from Hungary makes a much better cable. I didn't mentioned it because you have already ordered yours.
