A couple of months ago, we told you about the Acorn Preservation Team
, who are working to preserve the data from old discs before the data's gone forever.
Chris Evans and Phil Pemberton have written an in-depth look
at how they were able to recover the data from some damaged discs that were otherwise unreadable using more traditional methods.
The post is an interesting look at how even when it appears the disc may be unrecoverable, with the right tools there can still be hope of recovering the data using more analogue methods at the magnetic flux level (and sometimes drawing peaks on a waveform manually!).
Also, as we noted in the previous article, the Acorn Preservation Team are still looking to help preserve any unique, rare, interesting and potentially historic discs anyone may have tucked away in the back of their cupboards before it's too late. They're not only working on BBC Micro discs, but discs for other formats and systems, too. Links:Recovering "lost" treasure-filled floppy discs with an oscilloscope

The need to preserve data from the BBC Micro days is becoming more and more urgent as time goes by since many of the discs are now well over 35 years old and many will be starting to degrade - if they haven't already. During this weekend's all-day ABug event, the Acorn Preservation Team gave an update on their recent project to recover the data from the original source code discs for several of Matthew Atkinson's games for the BBC Micro including Repton 3
and The Living Daylights
The Acorn Preservation Team are also encouraging anyone who may have some old discs containing anything that is in need of recovery/preservation/archival to get in touch and loan the discs to them to help make sure the data isn't permanently lost. In particular, the team are interested in development discs containing sources, binaries, unreleased/missing/early versions of games and applications for both the BBC and RISC OS platforms.
In the case of Matthew Atkinson's discs, they were passed over to the Acorn Preservation Team a few weeks ago when they turned up here at TIB Towers after having been presumed lost by the author. It turned out that he'd in fact sent them to TIB back in the early 2000s where they were stored for the last fifteen years before turning up during a recent house move.
Once we'd sent the discs over to them, the Acorn Preservation Team set to work recovering the data contained within. This task wasn't entirely straightforward as some discs were showing the effect of their advancing age. One disc had damage that looked like it had seen an impact at some point in its life and sported a dent covering around 11 tracks of data. Despite this, the team were able to recover almost all of the data from the 22 disc set using a variety of methods including flux-level readings and analysing low level analogue signals from the discs. At the time of writing, only a handful of tracks from the dented disc remain to be recovered and are still being actively worked on. The data recovered so far has been provided back to Matthew Atkinson to have a look through and decide what he'd like to do with the soruces next.
Phil Pemberton and Chris Evans talk about the process of recovering data from Matthew Atkinson's source discs at this weekend's ABug event
The ABug talk from the Acorn Preservation Team will be made available through both the ABug website
and their new YouTube channel
in the near future along with a talk by Matthew Atkinson himself on the history of his BBC Micro and Archimedes development days.
If you have any old discs in need of preservation, whether BBC Micro era or Archimedes/RISC OS, the Acorn Preservation Team urge you to get in touch via the Stardot forums
or the Software Preservation channel in the Stardot Discord Server
before it's too late and the data's gone forever.

What better way to spend your free time this Christmas while we're not allowed to go anywhere than to sit back, relax and enjoy some interesting presentations on a variety of Acorn and RISC OS topics?
Since 2014, ABug - the Acorn and BBC Micro User Group - have been holding regular events featuring talks on a wide range of topics relating to Acorn and RISC OS computers, both as in-person events and more recently as virtual events. We've selected a few of our favourites in this article, but the ABug website
has a lot more talks available to choose from.

A special announcement from WROCC:
Along with the more obvious problems associated with the cancellation of
this year's Wakefield Acorn & RISC OS Computer Show came two less expected
As befitted the 25th show organised by the Wakefield RISC OS Computer Club,
Andy Marks of RISCOSbits had produced us a very special silver edition Deuce
case for the first prize in the raffle that we had intended to hold. With no
show and no raffle, the Club is now in possession of a totally unique, and
very special item.
The case is silver coloured, with the Club's acorn logo on the lid, and the
Wakefield 2020 (25 years) show banner engraved on the side. It is designed
to take a Raspberry Pi 3+, and comes with an adaptor plate for a Pi 4.
Details and photos can be found at:
The loss of the show also meant that we were unable to organise our regular
Charity Stall in support of Wakefield Hospice. Over the years the stall has
raised in excess of £20,000 to support their work, and at a time when
COVID-19 is having a great impact on charities, it was a shame not to be
able to add to that figure.
To this end, the Club will be listing the silver edition case for auction on
eBay on Thursday 3rd September, with the specific intention of raising money
for Wakefield Hospice. The retail price of the standard case is £30, but
given the unique nature of this particular one, we are very much hoping that
we can raise even more for the Hospice.
We would like to think that those who bid on the case and fail to win would
consider donating a similar amount in order to support the important work of
the Hospice in its 30th anniversary year at this difficult time. This can be
done via our JustGiving page, which passes the money direct to the Hospice:
In addition, donations from all members of the RISC OS community will be
The Club would like to thank all of our exhibitors and visitors at past
Wakefield Shows, and hope that we will be able to see you all again in
person in April 2021.

One of the great pleasures of writing for The Icon Bar (beyond the high salary, job security, long lunch breaks and editorial freedom) is when a package arrives in the post for review. While software can be sent via email, there is still a certain satisfying thud when an item of hardware arrives for review.

Recently I decided to upgrade my monitors. I have a MacBook Pro laptop and I have 2 monitors - one at work which runs my laptop (replacing a 27 inch 10 year old Apple work monitor) and one for home also hosts my RaspberryPi and Titanium. I wanted a high resolution (3840 x 2160 for work) monitor which would also play nicely with my other machines.
The latest Macs use Apple's USB-C connections. You can buy adapters for connecting in other types of connector such as HDMI or you can now buy monitors which have a USB-C connector. Apple offers an LG monitor which provides 5K and can also power the computer and handle the display on a single cable. If money is no object, you want an uncluttered desk and a 'to die for' screen quality on the latest Macs, the LG UltraFine 5K Display is the current top option.
Not only is this monitor very expensive but it will not work on my RISC OS kit as it only has a USB-C input.... One monitor which has also had a lot of very favourable press coverage is another LG model (27UD88-W). This is much more affordable (under 500 pounds), has USB-C input (not powerful enough to act as a power supply as well but fine to drive a 4K display), and also allows for HDMI and DP-IN as well. There are even a couple of old style USB ports for good measure. So how well does this model work for all the machines?
Very well is the short answer. The screen quality is great and you can have all the machines power up and then switch between them. The 27UD88-W has a single joystick type control under the screen and (IMHO) this is one of the nicest switches I have used on monitors - 2 clicks and I am on a different screen. The screen is ultra-sharp on both the Mac and the lower resolution Titanium 1920 x 1200 display.
One word of caution on moving up to a higher resolution screen. My combined switch box (which allows me to share screen and keyboard/mouse through one switch box) does not work on the higher resolution screens. So if you are using a switch box, you may want to verify what it can support.
A really nice feature of the higher resolution screen is that you have your other machines accessible via VNC. This also gives you some idea of the extra 'real estate' the monitors can give you if you are working on a Mac.
If you are looking for a godo quality monitor to provide a high resolution display, which also plays well with your RISC OS kit, the LG 27UD88-W should be one of your shortlist.
