Spectrum Computing

It may be helpful to read the "New Commands and Features" documentation here: https://gitlab.com/thesmog358/tbblue/-/tree/master/docs/nextzxos Sprite commands start on page 7 and there's something about automatic sprite movement on page 9. This document applies to the very latest NextZXOS ...

Can't help with your query, but amen to that sentiment! I've been diligently holding off doing any Next development until I have one, but I don't want to wait another year. There is a lot to the Next. I highly recommend becoming familiar now -- the emulators are partial but they do implement most c...

Pattern 0 is fine, Pattern 1 is a corrupt mess. This is the code: ld bc,$303b ; this sprite control port again xor a ; first sprite out (c),a ; select it ld hl, tiles ; 16 tile graphics stored here ld c,$5b ; copying sprite data goes via this port apparently ld b,0 ; 2 sprites worth otir If I split...

Whilst I remember, how am I getting Frogger working again then please? ;-) I take it that is some kind of insider release of Rams you have AA? I know I can play it on mame but the Next is really good for the old ports, much better in a way. Yes I have a special version. They're intending to release...

But it is their own fault. Instead of making the second Kickstarter a quick turnaround of the original Next hardware, which was what was originally promised, they started to tinker with it and make “improvements”, adding in things like 2MB of memory as a stretch goal. Well no -- it is clearly state...

@mausthekat Garry figures he's located the problem and it will be fixed in the next update at gitlab. Does the crash still occur after you've disabled the welcome message with "D"? (and maybe a reset afterward).

That is strange -- I can't get it to crash here. Does it also crash if loading tap from the browser? Both ways (physical tape and tap file) use most of the same system code. Maybe I should ask what video mode you use too (hdmi, vga-0, etc).

Does anyone else with an NGO have this problem?

May i ask what was the point of the raspberry pi zero, because after reading your post if they had the stop of the pie zero i would have had one fitted. Unfortunately they were out of stock. Is it so you can play other platforms games on the n-go? I already have a raspberry pi 4. The Next is a mult...

Did it crash on all tap files you tried? Would you mind trying to do it from scratch again by formatting the sd card and copying files onto a blank slate to verify it breaks? There is a new 2.07a committed a little while ago so fetching again from gitlab might be a good idea.

It seems like the latest gitlab firmware 1.31 isn't playing nicely with the n-go. The 3.01.10 core is okay, but I had to use the 1.30 firmware. On 1.31 selecting the tape loader resets the machine instead of showing the hardware selection menu. There should be no difference between a Next and an N-...

The N-GO is a clone of the issue 2B Next board found in cased Nexts delivered in the first KS. As Chris mentioned, it has fixed a couple of bugs discovered after delivery like the hdmi backpower issue where some hdmi tvs keep the spectrum next powered up even after it was switched off. Being a clone...

What was reported as not working on the Next? Was it just the dotx files or were the editor and linker (the tap files) not working either? I'm afraid I don't know - it's a report of "not working" without further details. So I just had a quick look to try to figure out every possible thing...

Originally I was pointed here because someone mentioned that specasm wasn't running on the Spectrum Next so I'll spend a few lines talking about that. The dot command is built with +zx as target and dotx as the subtype. dotx allows dot commands to be bigger than 8K by using some of the main ram. The...

There's one area I could do with a bit of help with. I've really struggled to get the keyboard input routine working properly, despite trying lots of different variations. The main problem with the current version is that sometimes, an additional character appears when two keys are pressed at once....

Very terse but complete notes are maintained at the fpga repository. These apply to the latest version of the hardware (3.01.10 / 3.01.11 currenty).

Frogger is a thing as I've been playing it for half a year. This is what Rusty Pixels had to say about it: Warhawk 2 may well happen. Frogger is working in rams. Just Jim Bagley and I need to bang heads and get it finished. We will this year Hunchback being three Signetics 2650s is a crimp that's fo...

Yes, I've seen several distributions of people claiming to have 'Pentagon Fixed' Buzzsaw+ , despite the game being able to detect and adapt to Pentagon timing all on its own. It seems to work on all timings 48K/128K/+3/Pentagon? It's listed as 48K in the archive. I guess it has to be listed as some...

Actually I don't think the random vector problem is primarily caused by improperly designed hardware, although that would do it. If such things exist, they would only be looking for /iorq to put something on the data bus rather than /iorq in combination with /rd and/or /m1. The z80's interrupt ack c...

So wait, are you saying that Joefish has just independently designed the Megadrive extension to the Atari joystick standard? :lol: I think that's genuinely brilliant btw. lol yeah probably. It was heading in that direction anyway since the next question is how can I get more buttons without comprom...

Is there any official standard for multi-button Kempston? The only thing I've ever seen working is Aliens Neoplasma but the additional button only brings up the menu rather than jump which would have been much more useful. This is when using a Megadrive pad on my DivMMC Future. The release post for...

Yes you must do it from the spectrum next kickstarter page. There's a link in the image in my post. You'll have to log into kickstarter first to see your pledge info. https://i.postimg.cc/DmJVtmVG/pledge.jpg Scroll down and you'll see the "campaign, ..." toolbar as shown at the top of this...

So you mean, the Spectrum Next can't be connected from its VGA-output to any VGA monitor? That would be strange, I think. You can, hence the vga-1 through vga-6 settings to make sure you can. The problem is the spectrum's video display is no longer compatible with any modern tv standards. So you ha...

James, this just turned up on discord:

A vga to rgb cable that apparently works for the Next / 1084 combination.

OK, so because the 50Hz video frame comes from the clock, it's a percentage of it or whatever, increasing the clock also increases the video frame? Since many monitors need 60Hz video frame, you can force the frame rate up to this by increasing the clock. Though you may have to experiment, by the s...

Are you saying that if there are timing problems I can try seven different values for timing? The spectrum next is still a spectrum underneath and it is a producing a video frame like the original spectrums. That means 50Hz display and a pal like structure to the frame. Not all displays can sync do...
