Spectrum Computing

Quite interesting that Richard, Gerard and David have been thrown under the bus as far as WoS moderation goes. Funnily enough whilst I don't always agree with them I've found them somewhat more approachable than the admin who purports to be acting in the site's best interests...

It is nice to see people's opinions here, and even nicer that people are allowed to express them freely

I presume Whacker's talking about the requirement for individual API keys for programmatic access to WoS resources.

Go for it guys, firmware link is in the initial post, and there are instructions on the wiki (link in my sig).

Well if the ROM's missing, it'll confirm that fact for you

Thanks Mark

Hi everyone, I'm in the final stages of preparing a new zx-diagnostics release, so I'm looking for beta testers :) You'll need to have a Diagnostic board, Retroleum SMART card, ZXC3/ZXC4 cartridge, Dandanator! Mini or a good old fashioned EPROM blower. Oh, and preferably one or more broken machines ...

One of the first things the ROM code does, regardless of memory state, is set the border to white. So if that's not happening then either the CPU is dead, or more likely in your case, one or more faulty RAM chips are holding data lines high or low. Since we have the data bus separator resistors prot...

Lucky I had them saved locally then Here you go:

Here's a link to a page describing ZX-MUX, which was designed to be a drop in replacement for the ZX8401/PCF1306/Amstrad 40058 IC's:

You'll find schematics and gerber files there, I've built a few using the gerbers and they work fine.

I absolutely loved Behind Closed Doors. Hadn't done any major adventuring before finding this on a SU cover tape.

For an explanation of the memory screen layout, see this page (by Chris Smith, this is the work that fed into his book): http://www.zxdesign.info/memoryToScreen.shtml - and for an explanation (a little technical) as to why this layout is important: http://www.zxdesign.info/dynamicRam2.shtml Basicall...

Think the +3 was £249 when first released, which sailed a bit too close to A500 territory in my view.

£199 would have been a nice initial price point, I agree.

A phrase I use a lot is 'we are where we are'. Everyone has their own viewpoint on how we got here, the important bit is how we continue.

Great to see so many familiar faces on here already

Hi everyone!

I'm Brendan, you may remember me from such things as zx-diagnostics (shamefully plugged in my sig), and from the Spectrum For Everyone FB group.

Just wanted to say Hi and best of luck with the site
