Hello Andrew - I have plenty of spare PCBs left, so I could certainly make a cable for you - the only issue is that I’ve just put my electronics kit into storage whilst I have a loft extension built - alas, this will mean a delay of a couple of months. However, I think that I do have an existing cab...

As mentioned, the university has several museums worth visiting, including the often overlooked Scott Polar Research Institute museum on Lensfield Road (there’s a glorious bronze statue in the grounds that was cast by Scott’s widow and which was modelled on TE Lawrence’s younger brother). Once you’v...

There are a few pointers on burning RO ROMs for RiscPC here https://www.riscosopen.org/forum/forums/5/topics/870 And it seems to be possible to deal with 42 pin 27C160s using a cheap minipro TL866 and an adapter board described here http://digicoolthings.com/eprom-programmer-adapter-for-27c400800160...

I've had good results with floppy disc cleaning frames, with both 5.25" and 3.5" discs - there's a link to a video showing the technique in this thread: viewtopic.php?f=16&t=15218

Here are the disc images - the attachment is a Zipped !Spark archive containing 800k disc images of the three 3.5" floppies that I received. The disc images work with !ADFFS. The three discs are: 1 the Informax app and associated support files including the Jotter font required by the app; 2 example...

Ah, yes! It would appear that my 99p bid was successful on this occasion. I will, of course, be more than happy to share the disc images and scanned documentation in due course....

I’ll take the last 16-bit card, if I may?

Richard - it would be great to see some progress on this; I'd be more than happy for a team effort, but I doubt that I'll be able to contribute much, if anything, in the foreseeable future. If you'd like to have a got at this, then you could ask RobC if he'd be happy to share his CP2201 driver code ...

Hi Richard - Unfortunately, the demands of my daily life have been such that I’ve not had the time to make any progress with this project. I have got the plipbox hardware, and RobC very kindly shared his CP2201 driver code with me, so at least I’ve got everything that I need to make a start, other t...

I recently managed to get an eBay purchased floppy disc working after cleaning the disc surface - see here: https://stardot.org.uk/forums/viewtopic.php?f=16&t=15218 Of course, if your disc has been overwritten, then cleaning won’t be much help, but it might be worth a try....I must admit that I was ...

Yes, please!

Should anyone be interested...

I am!
Many thanks for this - a most welcome improvement in the pdf!

Thanks again for sharing Kenelm

I’ve been keen to try out Longman - Nuclear Reactor Simulator for some time, but I couldn’t locate a copy - I’ve not tried searching for this for a while, but I don’t think it’s available elsewhere?

How do you transfer something which is bigger than a disc size with this method? Is there a tool for splitting/recombining files or a multi-part archive format? Here’s a utility to do that - http://www.steve-potts.me.uk/software.html#split - this method does work, though it’s a bit of hassle. For t...

I finally found some time to build up my remaining Econet Hub PCB, and fit it into an enclosure, along the same lines taken for the Econet socket box described on the retro-kit site here . I decided to use a 2.1mm panel mount jack plug socket to power the Hub via a jack plug to usb cable. This Hub i...

Can I have an Econet podule, a socket box, and 5 T-pieces please!

The programs are in BASIC and the book is a delight!

Contents pages and Preface below, to give you a good idea of the subject matter covered:

An 8-bit IDE v2 unit for me, please!

Thanks for the kind offer Dave!
I’ll take you up on that, if I may?
There’s no hurry from my point of view, so I’ll just post the chips to you next month, if that’s ok with you.

Nice to see another Econet coming together! =D> You might like to try JGH’s Talk conferencing app on your Econet whilst you work on getting an L3FS instance set up - see http://mdfs.net/Apps/Networking/Talker/ - I think Talk is much more fun than *Notify! There are a couple of old threads here that ...

I see from the “Design Security“ section on p4 of the datasheet that these PEEL devices have a security bit that may be set at the time of programming to prevent subsequent “unauthorized reading or copying of designs programmed into the device”. Furthermore, it appears that relatively few programmer...

Well, it’s taken me a little while to dig out and open up my A5000 with the Atomwide 8Mb RAM expansion card, but here are a couple of photos - it’s a fully populated version of DutchAcorn’s board. As the photos show, U4 and U5 aren’t GALs but PEEL PLDs - datasheet here: https://datasheet.octopart.co...

The other Longman titles I have are: Aural 5 Flowers Human Population Growth Investigating Circuits Micro Map 1 & 2 Pond Terrible Tales Winds Workers and Machines World of Newton Thanks for the uploads Kenelm! I’d very much like to see some of these other Longmans titles - Human Population Growth, ...

It would be great to have an Econet interface for the Pi, or the BBB - there has been an Econet USB project on this forum in the past, but as yet it appears not to have come to fruition: there’s this one from flynnjs - https://stardot.org.uk/forums/viewtopic.php?f=3&t=6065&hilit=econet+raspberry+pi ...

There’s a RAM test program in the A3000 Acorn dealer test disc here - http://www.lewisgilbert.co.uk/archiology/dealerdiscs.html - I’ve not had a chance to look at this in any detail, so may not be useful for testing RAM expansion. If the ROMs or dealer test disc aren’t suitable for test purposes, th...

For reference, the ACP ADT ROM (various versions) is available from mdfs.net - http://mdfs.net/System/ROMs/DiskTools/

and the documentation can be found here - http://8bs.com/othrdnld/manuals/applications.shtml

One board for me, please!
Thank you

Hello Andy, Are these cables still available? Is it a case of just replacing the floppy cable in my A3020 with this one to add an external FF Gotek? I still have some second floppy pcbs, so I could make you up a cable. The cable is easy to use; it’s just a matter of swapping the existing cable for t...

Looks like a pre-modded Gotek from RetroClinic, so I think we can safely assume the Gotek itself is good. The problem may well just be dirty contacts on the floppy drive IDC connector on the Beeb - try plugging/unplugging the floppy cable from the Beeb several times, and see if that fixes things. Th...

Now that I have 2 working Beebs, how about setting up an econet between the 2, then they could chat :) Is the econet option being sold in a similar way as an upgrade kit somewhere? Check out this thread - https://stardot.org.uk/forums/viewtopic.php?f=8&t=15086 You’ll need a second processor for one...
