Spectrum Computing

Don't you have a simple microphone ?

If you can listen to the sound, you can save the audio using a mobile phone for example.

I'm lost for words, to even comment this.

I just wish I could have access to my account to fix my threads in WOS to have the image links corrected.
But my account is still locked.

Apparently, they don't even value the content they have in there.

Nice parallax.
Nice Inertia in the movements physics.
Very smooth game [mention]Ast A. Moore[/mention] .

I believe the one you want is this:

Although it is for +2, he explains the problem in the intermittent RAS/CAS problem.

I would also suggest you see the previous one too, if something doesn't make sense.

I believe there is a video in youtube, by a guy named JoulesPerCoulomb, if I remember correctly, that found a timing issue on ZX that looks very similar to this. Should be easy to find. The solution I believe was to replace or add a Capacitor and a resistor, to delay a signal line. Maybe you want to...

... SOME emulators might have disk/tape autostart but not all and it doesn't work properly every time. Okay, most (if not all) other emulators run a snapshot immediately as the name is selected but there are use cases when it's not desired or inconvenient so i decided to actually run it with a hotk...

It covers on how to provide the argument files to the executable, but apparently that is not the only thing that is needed. See? This is what i mean. This time it looks like you didn't read @PeterJ's excellent message to the end. :lol: :cry: If after reading @PeterJ's excelente message to the end, ...

Instead of relaying on any assumption (and I know this is difficult to do, because we do not realise easily that we are assuming stuff, because they are so obvious to the person assuming them), a manual or README file should not, i.e. MUST not assume any prior knowledge, and simply list every singl...

Hopefully my tutorial covered that @RMartins. Yes and no. It covers on how to provide the argument files to the executable, but apparently that is not the only thing that is needed. NOTE: I haven't tried it or even read the manual. I was just stating, how I usually go about to make it more "us...

From my view, the problem seem to lay on the assumptions that each type of user makes (developer, regular user, power user, etc...). Instead of relaying on any assumption (and I know this is difficult to do, because we do not realise easily that we are assuming stuff, because they are so obvious to ...

Is the CPU socketed ?
Can you replace it and check if it makes a difference ?

My first games where:
1 - Space invaders (it was a clone, with a different name)
2 - AirWolf
3 - Commando

Are you using any modern power brick ? A switched-mode power supply . i.e one of those that are small and have an high frequency oscillator inside ? I have experienced a lot of interference, with some of the cheap ones. Usually some kind of wave going down or up the screen. But usually they don't af...

I would say, that your code is slow enough to process those lines, that the raster line catches up with the character you are changing the color at. Two easy fixes: 1 - Move your graphics to the bottom of the screen, and you will have more time, before the raster line catches up with you. 2 - Wait a...

It would have been a nice screen mode to have had on the Spectrum, but with direct access to read and write the video RAM. but character backgrounds are almost useless without hardware sprites, and hw sprites are too costly and too limited at that cost imo i would be much happier if the Spectrum ha...

The Memotech MTX500, MTX512 U.K. made computers also use the same video display processor (the Texas Instruments TMS9929A) as the original MSX computers. However they are not compatible. Mark The MTX line of computers, was one that really impressed me for it's quality and design. The computer case ...

... https://i.postimg.cc/mr0MypZB/31d2bacdfdb400167402eccaaedc661a.jpg Assuming the board does NOT have DIP components mounted on both sides, you still have some DIP square pins on the wrong position, that are not in pin 1 position, since they appear on one side of the chips but in some other locat...

... If you look at the pcb mask, the one that have the components layout, LED4 (green/red) with the 3 legs sawing the negative leg soldered in the ground (top side), but in bottom side of the board soldered again in a ground track ( bottom side) but that time through R1 resistor (91ohm) for current...

Wow! This is Perfect! I was waiting a long time for this, Thank You! A little suggestion, I've an omni 128, also a lot of rubber keys 48's, can u please add an option to change the cursors keys to be used without caps (ex. 5,6,7,8 keys) as this machines doesn't have a specifics keys for cursor cont...

Nichicon, are some of the best caps out there, if they are not fake (most probably are not). Without a picture is difficult to evaluate what you are seeing, but in a general if the output is still RF, it's going to have noise, no matter what. You might want to mod the RF into a composite video out, ...

Honestly I don't think there's a whole lot to do as long as nothing too weird is happening with the electronics. I would love to restore the face plate, but what can I do except try to paint the areas that have flaked off? I wouldn't be able to match the colour and I don't know any methods to print...

I might be a bit late to this party, but I have a suggestion PNG is an extensible format, it has chunks and every thing is separated into the proper chunk types. Any PNG compatible application, must process only the chunks it knows how to handle. So my suggestion is that we can devise a new chunk, f...

Since no one tried to find the problem, let me continue on that. The issue, is that when a POP happens, it can have a lot of balls in other columns besides the original where the POP started, if there is connection between balls of the same color to those places. This indirectly means, that there ca...

I've now added a scrolling (well, paging) tracker display synchronised with the music. You can try it here: synth-v0.1.0-0-g2bd8639_128.tap The problem is, the rendering speed is not great (even when the code is placed in uncontended memory) and this causes noticeable gaps in the song playback. Is ...

Hello RMartins. First i have to say that i am not well experience making pcb's. I do every project first for my own pleasure and practise. That's not a problem, since they are easy to do at home (photo-hatching process), for a single sided, board. However, for a 2 sided board, you need to be a lot ...
