Spectrum Computing

49 years young, since last March

The days don't have enough hours to do everything I want to do!

Cool concept with a nice and fast implementation. Sometimes, it seems that the green areas in a later level (that looks like a comb of RED/GREEN or RED/BLACK, that alternates, sometimes the GREEN doesn't seem to replicate more virus. I'm assuming, it's to keep the frame rate high, and hence you are ...

Hi @RMartins, Things take time. We don't update the live database. When it's done you will see a green tick on your post. Sorry, it was not my intent to seem pushy. I know things take time. I was just giving feedback on my part. NOTE: I have been having some web problems with SpectrumComputing.co.u...

Steve Wilcox from Elite won't allow downloads. I've approached him a couple of times.

It should be distribution denied.

Yep, my point was that the info on the page is not coherent.

I just checked again and it's still incoherent.

Airwolf, shows as being available, but none of the files can be downloaded or played on browser.

Very nice photos and nice Museum.

Lost of Retro machines have been destroyed.

Just sent my Speccy off to Mutant Caterpillar for a refurb, looking at treating myself to one of these as well - came here to ask whether I could load from tape and save to card, in order to preserve my terrible type-ins from the 80s. Looks like it's a Yes :) Yep, you can. And it's even easier when...

Just for note, last Saturday at 18:20 (UK/Lisbon time) the site was down.

This time it didn't appear to be a DNS issue, but just the fact that the site was not responding.

... Specasm is written in C and built with z88dk. The keyboard entry routine is here . I'm using z88dk's in_inkey() function to read the key. A loop is started after the key is read, in which we re-scan the keyboard a fixed number of times, sleeping for 20ms in between each scan. We exit the loop i...

In your case you'd make C=0 every time. ; xy2screen: ;arrive with B=y 0-192, C=x 0-255, return with DE at corresponding screen ld a,b rra rra rra and 24 or 64 ld d,a ld a,b and 7 or d ld d,a ld a,b rla rla ...

Unable to load the ZIP on Zero emulator.
"start index can not be less then zero"

It has a weird directory in the ZIP.

Sad news.

I did some reading up last night and apparently a common cause of intermittent issues are extensions. Therefore I have temporarily disabled some recently added ones. These are Smartfeed and Dark mode. With these sorts of issues it's often a guessing game! That Dark mode, was really bad too. Not tha...

Nice story Bruno.

I'm assuming by the radio silence all is OK. It's really useful to know if things are fixed.

Sorry, I have been busy.

But yes things are OK now. Hasn't failed again.
I said it was working in a previous message.

So I was saving for when it failed again to post something with details.

Maybe just do a search by date, and download away the ones that are freely available.

But the arrow starts as a tipped flame, but, when flying there is no flame or even the thing that holds the flame. An arrow also doesn't turn in mid flight, that is what the feathers in the back are for, stabilization. some (most?) arrows do spin, exactly because they have intentionally curved feat...

As an aside, I've a friend who is now working from home, and if he doesn't move his mouse every 15 minutes a report goes to his manager!

LOL

What an old fashioned and dumb way of controlling the work of someone.
So if he is typing, it doesn't count ?

The arrow sequence on the intro is quite simply the best graphics I've ever seen on a ZX Spectrum Technically and artistically, yes. But the arrow starts as a tipped flame, but, when flying there is no flame or even the thing that holds the flame. An arrow also doesn't turn in mid flight, that is w...

You can't plug an actual Kempston Mouse into that. It's for USB or PS2 mice (depending on the socket fitted). That 9-pin connector is for a joystick. In the original form you could plug in an Amiga mouse there, but I don't even know if that feature is still supported. Well, judging by the documenta...

I don't know either what would be the best control keys layout. It's quite OK for me and I understand the reason. I just saw that it wasn't very comfortable for some people. Maybe an option for using more than 5 keys. As for the 3D part, they tried to play it, they could rotate the board etc., but ...

Joefish wrote: ↑Thu Feb 17, 2022 5:48 pm As far as I know there aren't any modern interfaces that you can plug an actual, original Kempston Mouse into. They all take USB or PS2 mice. And you'd be hard-pressed to get hold of an original Kempston Mouse Interface these days.

There is at least Velesoft K-Mouse.

I mean a physical Kempston Mouse, working with the exact same principles, a simple directional encoder for each axis, to be connected and used with a real ZX Spectrum. I'm not planning on building the interface, since there are several original ones but also modern ones that support it, but it could...

I initially had planned to make each Totem drop, force a rotation in its own direction. But from initial testing, I thought it might generate disorientation, since dropping 3 times in the same direction (same totem), without having one of them unlocked, would make it a lot harder to play, since the ...
