Spectrum Computing

What type of bit are you using on your iron? A chisel tip is what I recommend. Is the tip clean? Did you "tin" it? For normal tracks/pads, an 18W Antex should be okay. But is not very useful for the thicker tracks, like those used for the power supply or ground (0V) circuits. I use a Antex...

No worries

You do not need 9V, when using a regulated power supply, since it will make up for the extra power when it is requested. The required minimum voltage for the 7805 to work is 7.5 Volts. Everything above 7.5V is usually dissipated as heat, so not useful. If you do not have any extra peripherals, chew...

What are the risks of running this machine using the original 1980's capacitors? If I invest 60-70 quid on an IDE/MMC device, do the old capacitors pose a real risk to damaging the add-on? The biggest risk with a ZX Spectrum 16k, 48k (or Plus), is an electrolytic capacitor in the DC/DC converter fa...

I'm in the U.K. and I have no problems accessing AtariAge.

Err, both the Z80A and the 6502 (the 2MHz version) can actually "load" data to RAM from a high speed serial stream much faster than most people think. And Sinclair had already come up with a "high speed" loading system - the microdrive :P Amstrad however, with the ZX Spectrum lin...

Having read through all the posts in this thread, regardless of the "why not at any time" vs. having a restriction, I don't recall any reason why two hours was chosen as the limit. I can understand having a restriction. But would much prefer the time limit to be a bit longer. Two hours is ...

* Yes, Toni is a woman, and contrary to certain rumours, not transgender. The speculation about transgender almost certainly comes about due to some early print runs of Mastering Machine Code on Your ZX81 with the author as "Tony Baker". In later editions, the author was "Toni Baker&...

Any news on when a 2nd round of orders might start..? or when the next schematic is made available to clones? That I don't know. But hopefully everyone who ordered a PCB only, or a PCB with the rest to follow, should now have their PCB. I understand that some PCBs have been held up within the vario...

@Whacker post Use these links: http://live.worldofspectrum.org https://www.creative-spectrum.co.uk @ everyone who is hurling mud around the place. The unfounded accusations and bad language are not needed. The WoS forum has a team of moderators (or administrators if you prefer that term). It is the ...

One BIG concern I have over WoS right now, and I see this echoed from many sources recently is that all resources, be it manuals, schematics, publisher history, etc. is that it's being placed in a manner where there is a notable sense of gatekeeper access, trying to wall off information into a clos...

We all share the same concerns about WoS decline and all the valuable information it contains. Err, you have Martijn to thank for the decline of WoS. When he found true love, he more or less abandoned updates on WoS. And then after the site trundled on for a number of years, the server became unrel...

Yes, with the 128k machines the hardware is capable of displaying a screen from one of two available banks. See here for more info... The main limitation is that the normal screen memory stays in the normal place in the Z80 memory map (0x4000 and 0x7fff) and can't be paged out of this area. This doe...

Happy Christmas to everyone. And may the New Year bring less fighting in the Sinclair community

Good to hear

I'll send round the angry creditors then...

More seriously, has it actually been fixed?

Can the original poster please try it again and report back?

Mark

Yeah, but i'd like a trailer to carry the rocket parts...

Extra things to pick up, things to do, a rocket to construct and a proper game ending.

Like a trailer?

So I've just worked out what these icons mean. https://vgy.me/Uf6nNZ.png I'm so clever. ...Though at first I did think the fire one might be "flame war occurring".. :lol: Blue means read. Red means the thread contains unread posts. The star / asterisk means you've posted in the thread. Th...

If it has never been a commercial product, hence there is no price, then would it be better to show "N/A"?
The licence should be shown separately. Then you could have a hyperlink to a definition (like you currently have).

You'll need to have a Diagnostic board - yep, check! Retroleum SMART card - yep, check! ZXC3/ZXC4 cartridge - yep, check! Dandanator! Mini - yep, check (although I have no idea where I have put it :roll: ) a good old fashioned EPROM blower - yep, check! Oh, and preferably one or more broken machine...

We have less time for Speccy games these days, and a google times more distractions. Most people play in an emulator with snapshots, hacking is easier than ever, and POKEs usually appear within a few days of release. Is it even worth trying to design a game around a limited number of lives anymore?...

Thanks for the link 8-) That indeed is one of the better Christmas tunes. TBO, by the time Christmas Day arrives, I'm a bit fed up with most of the Christmas music tracks, because they get played to death. And now it's the same every year. Am I getting too old now? Converting that to a bleeper tune ...

In the past when I have used graph paper to design UDG and graphics, at first I always manually calculated the decimal value to enter into the Spectrum. Soon after, I started to use a scientific calculator that has binary, hexadecimal and of course decimal modes. Much easier ;) Now I have an iPad ap...

Not trying to draw parallels to anything. My comments just reflect my own experiences of how, sometimes, events don't go the way that is expected. And for the record, I'm just watching, as I already voted weeks ago. Anyway, since you posted that it's currently a draw, there has been another vote :D ...
