Spectrum Computing

The silver anti-tamper stickers are still present on the screws Should I still look?

I know this is a speccy forum, but I thought someone here may also have a fondness for huge slabs of beige plastic. A friend has had to clear out to make room for a baby, and I have offered to test and sell some Amiga gubbins. All proceeds go to baby peripherals. The Amiga is aged and well yellowed ...

I think the development of ZXBaremulator is over now, and the developer has said he will not be fixing the pi zero audio problem. Pi zero does output analogue audio on the GPIO but the pins are shared by the magPi keyboard interface, the dev did not want to change pins from the original magPi projec...

Z80 Heaven states : CP N Unsigned If A == N, then Z flag is set. If A != N, then Z flag is reset. If A < N, then C flag is set. If A >= N, then C flag is reset. Signed If A == N, then Z flag is set. If A != N, then Z flag is reset. If A < N, then S and P/V are different. A >= N, then S and P/V are t...

I just checked the pi Zero prices on ebay. My gast took some flabbering.

I have a W in the shed but it has no pins

I really want one of these for my speccies, so I guess I will be taking my chances soldering the header.

@PeterJ I can reprint this if @TomD can send me the gcode. I don't need the .stl files that way. I can post my printer specific g-code. Sounds like a re-print is what you need.

777 I have just realised you are working from some code I wrote on an old thread, complete with my cryptic annotations :oops: , at least I had credited Steve Wetherill in the notes. :D That code was pretty botched and messy. I used floating bus to see if I could do the cube draw in one frame. I cou...

@777

The sync routine is the floating bus hack developed by Steve Wetherill.

Scroll down to the Sidwize section.

This routine will hang forever if it is ran on a 128k machine.

Just in case I'm not around when they deliver. https://c.tenor.com/v0cBeb_yBgUAAAAC/its-been84years-titanic.gif Jokes aside, I am a bit disappointed with this announcement but I do remain optimistic that I will one day receive the Next. It would seem that FPGA's are used in many products from car v...

NextUX would have been cooler

Looks like a fun project!

Does anyone have a zx80 PSU and can measure the case? If a case is out there, i can draw up the shape and post the drawing, and the dimensions can be added.

Design it to accept a separate earth pin that pushes through like standard plugs? I think that would be the best way. I was interested to know what 'innards' [mention]jojo[/mention] was going to use, It may be that the original had an inserted earth pin already. It may be that on the original, the ...

If you are making the console yourself, the Pi Pico option sounds good if you can master it. For a console you would need a macro for the J shift-P shift-P, a simple 'start game' button. https://learn.adafruit.com/diy-pico-mechanical-keyboard-with-fritzing-circuitpython/code-the-pico-keyboard : Adaf...

I have always used a PS3 controller with a USB lead. I think you have to stick to the controllers listed on the ZXB website, there is a reasonably long list but they are all from consoles. Anything off list will be 'suck it and see'.

I missed this, so late reply. The two USB dongles are for when I use retropie on the same box. I have abandoned this setup now, because the GPIO/ZX keyboard is hopeless outside of ZXBaremulator.

Why do you need the print? Is it to repair a broken PSU and you have the original transformer and PCB? or will you use a modern PSU circuit inside? I ask because looking at the original PSU, it would be hard to 3d-print the earth pin in a way that would guarantee it would not snap off in the socket....

I played multiple rounds on Troon . My dad ordered the game from a small-ad. The cassette was cased with a photocopied inlay that had typed or handwritten sections. I was worried it would be unplayable. Once loaded up it was clearly written in BASIC, using INPUT statements to 'line-up' your shot. Th...

For my +2 grey, I use a very simple composite video lead I made myself. I was lucky as I had the right DIN plug in my random plugs tin. Pin 1 on the RGB DIN is composite. I also made a small mod on the board to decouple the audio from the composite line. I think pin 1 feeds off the signal sent to th...

Hi [mention]nenebien[/mention] I am assuming you have read the magPI 67 article. I refer to KB1 and KB2 which is used in the article for the two keyboard connectors. KB1 is 5 lines, no diodes. KB2 is 8 lines with diodes. For a sinclair 'left' port: Connect the common to KB2, line 1, which is GPIO 25...

If you use the command %fsconfig you can set the filesystem permanently and also toggle the autoboot setting, all via a menu. After you exit the menu, reset the spectrum to apply the new settings.

[edit] If the problem is at the Mac end (firewall?) I cannot help much as I use Linux.

[mention]cat[/mention] It works exactly like the original, so all original documentation is the same for Alexsey's card. The documentation for the card itself (the switch functions etc.) is sent by Aleksey and is the only card specific documentation. 'Tis a fine card. I play around with assembly and...

Runs (or is it gallops) just fine on a 48k machine with an AY card.

[mention]mdr[/mention] , The magazine covertapes section loads fine. Selecting 4 for Games gives '4 Out of memory 116:2', so it never leaves the Mani Menu screen. I have been doing some testing in FUSE and your site works just fine in emulation (my FUSE setup is a clone of my hardware). I have an un...

Hi [mention]mdr[/mention] , currently I am getting a '4 Out of memory' when I select anything from the main menu. I am using a 48k spectrum +. I have tried 2:Scene Demos, 4:Games and 9:Message wall, all giving OOM errors. I will try a few tests with FUSE later on to see if it happens with emulation....

This looks good. I had some hours of play of Zosya's previous driving game 'Drift', the presentation and game engine were beyond belief. Unfortunately I did not have the skills to do the game justice. I should give it some more time because when you got it right the game was really satisfying. Looki...
