Welcome, Steve. :D That dead key can be repaired very easily (probably). Unsolder the key from the keyboard, unscrew the solder pins one at a time, clean with 1000 grade wet and dry paper, screw back in, check switch makes contact, replace key switch. Failing that, wait until CMcDougall comes along ...

Enjoy the meeting, guys. I shall be with you in spirit.

At the moment I am looking after a very poorly dog for my daughter.

Thanks for that. I'll add it to the archive.

Welcome.

Does this happen:

a) on the same disc in DOS on a PC,

b)if the files are copied onto a RISCOS disc on the A4000?

The flaxcottage.com website has the BBC micro variant plus documentation. The 4corn website has an excellent copy of the documentation as well.

Surely it's x 1/root(2) not x root(2), it has to be less than the peak as you're filling in the troughs by chopping off the peaks. So 10VAC = 7V DC. No it's x Root 2 because the barrery will charge to the PEAK voltage of the rectified waveform, not the Average. It is usual to have a Reservoir and s...

There are two issues of Games Computing on eBay at the moment. I have a bid on the December 1984 issue as that is missing from my archive. https://www.ebay.co.uk/itm/Games-Computing-Magazine-December-1984/323908707796?hash=item4b6a76a5d4:g:rwQAAOSwdxlddQF~&autorefresh=true. If I win, once it is arch...

If you extract the zip file on a desktop PC other than one supporting RISCOS all the extracted files will have the wrong file types set and therefore will not work correctly on the A3000. There are two ways round this; 1. if you know the original file types then set them manually on the extracted di...

I used this way back in the day to learn all about electronics. :D IMAG1769.jpg My father bought it to help him repair things electric around the house. I just liked it for the radio circuits; IMAG1768.jpg When my father died I had the contract to clear out his shed and I rediscovered the book lying...

Welcome, B.

Now if this sells I'll be amazed.

I guess you've tried selecting Mathematics in the BBC Archive section of John/flaxcottage's website (which I can't seem to deep-link to)? You cannot easily make a direct link to maths programs since the display page makes extensive use of database queries to extract the required software and the pa...

Works OK for me using BeebEm 4.14.

Have you made sure the disc is not protected when it is loaded into BeebEm? Check in File-Disc Options.

Try these...

Several ROMs will self-wipe on Break or Ctrl-Break as a protection method when loaded into SWR. :( That behaviour is independent of OS. Images of these ROMs are available for download from various places on the internet. If you list the ROMs showing this behaviour forum members may well have version...

Very well done!

Moving in is attached. It is one on my to-do list.

Water manager cannot be posted as CSH aggressively protect their copyright. It is missing from my collection anyway.

The SD card attached to the printer port will behave like 4 separate disk drives 0 - 3. To use one you can type *DRIVE n, where n is 0 -3 inclusive. To load a particular image use the *DIN command, for example *DIN 15 will load the disk image from 'disk 15' into the currently selected drive. The con...

Welcome, John.

The discs you mention are standard 40T 5.25" floppy discs suitable for a 40T or 40/80T double or singe sided drive on a BBC micro. They can hold 100K on each side reliably.

BITD we used to format these at 80T. Some worked some did not.

I used one of those Sinclair calculators BITD and though it was wonderful, much better than my slide rule.

Once I got my Texas SR-56 though I stopped thinking that.

Yes, I am missing quite a few of the modern ones - all the ones without pictures.

Any that you can manage will be very gratefully received, thanks. The zipped files for one issue will be large so a Dropbox link would be the way to go.

I've sent you a PM.

Welcome, Vincent.

Cool.

Nice machine. They are my favourite Beeb.
