Sorry, C64 had also on floppy disk, but i could forget it , as I see, the spectrum, and TVC demo cassette also written in BASIC, or looks like a basic program.
Is it possible these demo's were written for the users? They can see, what they can do in basic.

Some interesting thing about TVC: bug fixed in WinTVC emulator.
Now can run VTDOS cartridge. And it is the "IS-DOS" for the TVC! Previously I never seen this!
This package contains ROM files and system disk image.
For try it: select 64K+ machine (Gép/Típus/TVC 64+ )
Insert disk controller ROM: File/IO kártya illesztése/ select one of DOSHBF ROM files.
Insert VT-DOS cartridge: File/Cartridge betöltése / select one of VTDOS ROM files.
And finaly insert the system disk: Lemez/diszk behelyezés/A: meghajtó

The structure of system disk are very similar to IS-DOS disk! And most interesting the file dates!
It is looks the last version compiled at 1987 May 19.!
At this day launched the Enterprise in Hungary!

Now I've rebooted, it's working! Amazing to see it again!

TV advert of TVC

Thank you - very interesting!

1988...if Spectrum, C64, Enterprise etc were available I wonder how they managed to sell any?! How important to people was it that it was Hungarian made? And had a Hungarian keyboard?

Yes, it had a hun keyboard

I was wondering how important the Hungarian keyboard was to the TVC's popularity, as I'm guessing Spectrum, C64 etc. didn't have a Hungarian keyboard available. And perhaps an important factor in it being chosen for schools?

In those days the hungarian keyboard layout was not so important, if I know well only hungarian computer which had hungarian keyboard was TVC that time

if I know well only hungarian computer which had hungarian keyboard was TVC that time

Primo also have, but not full, only for the most important characters.

Question from the Hungarian forum:
The Enterprise have lot of extra keys: Function keys, ALT, CTRL, ERASE, DEL, INS, HOLD, STOP, etc.
Where did the idea? For example existing CP/M standards?

The case and keyboard design were done when I started, but most of those keys were already fairly standard on "big" computers of the time (don't forget the original IBM PC was released in 1981). Built-in support for HOLD and STOP was a bit more unusual - I think they came from Robert Madge's drive to make things as simple as possible (in CP/M it is CTRL-S to pause and CTRL-C to stop, but they are implemented in the character I/O functions, so if the program is not performing any character I/O you cannot stop it). The "soft" and "hard" reset also came from Robert Madge - I remember all the programmers (including me) were very dubious about resetting the Z80 in the middle of eg. a crashed BASIC program and then expecting to be able to get back the BASIC prompt with the program in tact, but I have to admit it works surprisingly well!
