Last time I tried on a iPad mini, the site would not work (it did earlier in the year). I no longer have this iPad. On the device that I am currently using, it does work (the link that Peter provided) and just going to the site via its URL so that you drop into BASIC. https://i.postimg.cc/JswcC1cn/S...

Okay, here's screen shots of those pages: https://i.postimg.cc/Z9pQz7dk/Screenshot-20240511-115151-kindlephoto-1591083851.png https://i.postimg.cc/0MvBkYYz/Screenshot-20240511-115226-kindlephoto-1591218515.png https://i.postimg.cc/wykb7120/Screenshot-20240511-115249-kindlephoto-1591176133.png Mark

Sorry if my poor English doesn't completely understand what you are saying. Are you suggesting me to DM/PM you? If Lee does communicate with me, he is very likely to want to know your old email address and your new email address. It is entirely up to you if you want to do this. I am just trying to ...

I don't know any details on the forum software used by WoS, but on phpBB forums, the powers between moderators and administrators can be very different. Even the powers given to the moderators can vary. A standard moderator can only ban users, not change their details. But the administrators can giv...

Well, it all depends on what you are trying to do. Which takes up the most space, executable code or data?

The all RAM mode is only available on the +2A, +2B and +3 models and was presumably intended for CP/M use.

I'm happy to add other users that are unable to log in to the WoS forums to my topic on WoS forums.

Please quote your WoS forum user name. And it helps if you PM / DM your old and new email addresses in case Lee or another WoSf admin asks for them.

The problem is that Lee does not appear to visit the WoS forums very often now.

I posted a topic about a new user wanting to join back at the beginning of the year, but there was no reply to the topic...

I'll add you to the same topic later once I've found it again.

What does it exactly mean? Brand new Z80 MPUs and the support chips for it that were still available will no longer be manufactured. Yes, there are plenty of used Z80 MPUs on the grey market. But as with many things on the grey market (including trading sites like eBay) what you actually get may no...

This printer needs a PSU with a 24V 1A AC output.

Okay, that's weird... The keyboard matrix is pure hardware and what program is running shouldn't make any difference to the hardware. Having said that, BASIC and some games will ignore a key if two of the normal keys are detected to be pressed simultaneously. That may explain why the symptoms are di...

So, over the lifetime of the Spectrum, there were various changes to the circuitry including that of the DC-DC converter section. The website/blog you linked to is mine BTW. On your board, you may have either an earlier version or it has just been implemented differently. The service technicians tha...

It may be that the problems with the keyboard existed before you opened the case. Were you able to test it before opening it? The keyboard uses a membrane, which itself is wired as a matrix of "switches". The "normal" keys (those that are the same as in a rubber key model) use a ...

With faults, I much prefer members to start a new topic. This saves confusion. However, I'm not an admin or moderator here.

So, just the few instructions needed to switch banks then I guess? I was expecting a bigger speed penalty to bank switching. The latch chip that stores the extra address bits for the memory is just as quick as the Z80. The limiting factors are what you have to do in your software routine and the OU...

I assume you were using an original Sinclair power supply unit (model UK1400 9V 1.4A). This is not a universal mains voltage type, as it requires a nominal 240V AC 50Hz mains input voltage. It will not produce enough output voltage if connected to a 110V – 120V 60Hz mains supply. The good news is th...

1024MAK

Yes, it has definitely been modified. The (phono) output connector on the modulator (what was the UHF TV output) will now output a composite video signal. I can't tell which version (there are more than four...) of the composite video modification has been done. If you want to know, you need to care...

Oh, and during the RAM check that the ROM does, it may be possible to check for some RAM faults that the ROM code does not test for. It's not possible to pick up all RAM faults, because the intention of the ROM routine is to simply work out how much RAM is fitted, NOT if it works correctly. Hence th...
