I always thought that using the pound symbol was a nice characteristic of the computer. As nice as the channel concept, that I discovered by first time on the EP.

Or maybe # is more useful than £ in IS-DOS, especially considering most use is in Hungary, so just change £ to # permanently in new IS-DOS?

Both the Hungarian and German language ROMs for the Enterprise already change the "£" to a "#", and the world, even in the 1980s, confirmed the decision that ASCII code 23h was a "#" and not a "£".

The American-designed Apple II, Atari 800, Atari ST, Commodore PET, Commodore 64, Commodore Amiga, MSX, and the British-designed Amstrad CPC, Amstrad PCW, Camputers Lynx, Memotech MTX512, Oric, Oric Atmos, Sam Coupe, Sinclair Spectrum, Sinclair QL, Tatung Einstein, Acorn Archimedes, and even the Acorn BBC Micro, yes even the BBC, the bastion of British culture, all agreed that ASCII code 23h was a "#" and not a "£".

Although IBM computers had special British keyboards available with a "£" instead of a "#", they put the "£" at a different code point (A3h).

This battle was lost a long time ago, and the Enterprise was on the losing side of the fight.

That is why I swapped the positions of the "#" and the "£" when I recently released my font changes for the EXOS 2.4 ROM and all of the international Language ROMs.

I really don't want IS-DOS to change the current font, because that conflicts with the user's choice of their own font.  The widely-used Hungarian HFONT extension, together with my modified Language ROMs, modified HFONT and modified EFONT, all move the current font basline down by a pixel so that accented characters (and all inverse characters) look better on the screen.

I really don't want IS-DOS to change the current font

Anyway, it is funny for us Hungarian because the word "font" means "pounds" in Hungarian. The British currency. You can imagine when we heard the word "font" for a character set for the first time, we found it funny because we thought of the currency. Someone who is not good at informatics is confused when we speak of a "font". (Everybody knows here what the British currency is but not everybody knows about character sets.)

I don't remember where I downloaded these files from:

Probably here!

The problem with those games on IS-DOS is because of two things ...

1) They use some Heath H19 escape sequences that not supported by either IS-DOS 1.0 or my recent IS-DOS 1.1-alpha.
2) They send a truncated (i.e. wrong) escape sequence that confuses IS-DOS.

I will change the "fast" video driver in IS-DOS to support all of the escape sequences that the games need, and also upload a fixed version of the .COM file.

The company that originally released the games on CP/M also provided this file to customize them for different terminals ...

2) They send a truncated (i.e. wrong) escape sequence that confuses IS-DOS.

What is the difference between the above and the version here?
Looks like it works.

64 columns give us a clue of the original computer to which these versions were tailored.

I have searched and I have found the TRS-80 and the Exidy Sorcerer.

But I also found this assertion:"The original video displays for S-100 machines were normally 64x24 or 25. Practically every machine used this mode. 80-columns did not appear until well after CP/M was widely used."

Of course, on that web page there is somebody denying it.

Thanks! Infocom games updated.

Thanks!
These .dat files have been included in the downloadable games.
Almost all the old ones were longer. It was rubbish at the end of the files.
