Re: Oricutron on Chromebook

I still think my Oricutron isn't using OpenGL though. Is there any way to tell from its UI once it's running? Yes, press F1 to pop-up the menu and select 'Video options...' (or press 'V'): Screenshot_20230330_195524.jpg You can use this menu to switch the render run-time. Other ways to do the same ...

Re: Oricutron on Chromebook

I'm beginning to wonder if I have opengl at all in my Linux setup? When I type glxinfo in the terminal, the command is not found. Try to install 'glxinfo' and 'glxgears', for my Linux distro (Fedora) they are in package called 'glx-utils'. If 'glxgears' runs then Oricutron should run too with OpenG...

Re: Tantalum capacitors C3 and C4

I never had nor heard about problems in Oric with these particular tantalum capacitors. This topic is indeed interesting and worth more in depth investigation - how C4 can affect the noise. About the polarity - both (C3 and C4) are polarized and it's important to be soldered in the right direction. ...

Re: Sharing my experience of an Atmos resurrection (thread)

Indeed, $98A <= X < $999 vs. yours $98A <= X < $9E9 i.e. threshold $0E vs. $5E or interesting is why difference is so big.

@mikeb checks exactly for the value 0x98A. You set the threshold up to 0x9E9, why so much and where from comes the big difference?

- mos6502vm's disassembly output now redirected to stderr (instead of stdout), so you can 'pipe' it to file.
- added sample eight-queens.

The 259 syncs only really applies when regenerating the audio.
Indeed. Here is TapOric which is exactly an adroid player for TAP files.

btw, any change for non Windows version of NUTS? :)

Re: Seeking tape and disk image knowledge

Welcome here, @Rebecca! Your work is impressive, congrats. About TAP file format: you already have the best descriptions and I don't see what can be added. Slow and Fast are just transmission protocols and have nothing in common with the data inside a TAP file. You have to deal with slow/fast protoc...
