Where can I find "true" ZX81 fonts

[blittled]

I am working on a project and I need a windows font with the all the graphic characters. The ones I find do have the alphanumeric characters and their inverse but no graphic characters.

The ones

which one ?
The Xur encoded ASCII font can display all graphics characters… ('Zx81_Fonts' directory)
[Copy&paste] the characters from the 'ASCII_TABLE.TXT' text.

Text files in the XuR.

[Edit] Use the true-type (TTF) font on Windows 10, the FON one is provide to run on W95>XP.

Thanks. I'll try them out.

I've always wanted a ZX81 emulator with an IDE that single steps Basic and Assembly and is able to dump the contents of variables like IDEs such as Visual Studio. Since I am a programmer and want to try working on an emulator I'm giving this a try. I have had a couple of false starts on this and hopefully I'll continue on with this attempt. To make it easier I am using some existing code and libraries I can get for C# in Visual Studio such as Z80DotNet for the Z80 emulation and AvalonEdit (which is the SharpDevelop IDE) for the IDE. If I do get it to a working release I'll post a new thread on it.

Do you know Wilf's NOVA? It supports "BASIC line number trace". Maybe that could be used to implement Single Stepping at Basic level...

And Single Stepping in Z88DK compiled C programs would also be nice to have

siggi, those are interesting links and may be something worth implementing once I get things going. Right now I'm having fun trying to implement the interrupts required to do the display. The Z80 engine I'm using counts t-states so I'm using that for the 207 count for the NMI. It isn't exact but since I'm dumping bytes onto a simulated display and not a real tv it doesn't have to be.

I wasn't going to say much on this since I always post grandiose plans on things and never follow through. I do work by day as a .Net programmer (C# and VB) and have to deal with some pretty tricky stuff so at the end of the day if a personal project starts getting difficult I tend to lose interest. That being said here are my plans:

To have something up and running next year for the 40th anniversary of the ZX81. I will be working on a source debugger that will work with a mix of Basic and assembly. It'll will be loosely modeled after pokemon's FASMW-ZX but since it will have an embedded emulator I'll be able to examine the code directly in the emulator. Also the Z80 engine I'm using has "watchers" that can fire events when user defined conditions are met making breakpoints a lot easier. I eventually want to add as many tools as possible to make this a "one stop" development system. I also am coding it so it can eventually be used in ZX80, Jupiter Ace and Spectrum emulation. My ideas are somewhat grandiose so this will take some time.

That sounds familiar.

I'm glad to see I'm in good company
