That's a great photo! I think that it captures something of the spirit of this heroic endeavour!

But, your photo somehow puts me in mind of the Titanium Cyborg from the Fighting Fantasy title Appointment with F.E.A.R ...

Hi Liam Great, if you did have the latest version that would be cool - actually if you did have a board still spare I would be happy to give you a couple of quid to post it to me, as it would be a quick way to learn a few useful physical things about the DIN connector footprint...! Cheers, Alex Hi ...

What a delightful bit of retrocomputing archeology! Thanks for unearthing this Lurkio! Very cool. Presumably the "Heath" mentioned is something like the Heathkit H8, H88 or H89. Spot on! There’s a section at the end of the Recreational Computing article as follows: Documentation and Dissemination Do...

Would it be OK for me to get a PCB made while I am ordering some of my own designs to be made? Hi Alex! Thanks for your interest in this board - you are very welcome to take my Eagle files and use them as you see fit! I think that I made some further “improvements” to the design since I uploaded th...

PowerIDE uses the native IDE interface in the A3020 etc, I don't think it'd work with this :/ d. The feature list for PowerIDE says: “Supports Compact Flash devices with a suitable 3rd party adapter” I think it will be worth checking with Partis before writing off PowerIDE; even if it transpires th...

It's a Alsystems IDE interface, branded "Power-tec" on the back. According to Chris’ Acorns http://chrisacorns.computinghistory.org.uk/Companies.html#Partis - Alsystems sold Partis products under the Power-Tec brand - Partis is still in business, and it looks as though their PowerIDE software is wh...

Fantastic! Many thanks

I have !PiRat somewhere. I remember using that to clone an educational title.

Investigator III is on my hunting list, thanks.

Any chance of uploading !Rat to the forum? Sounds like a handy thing to have around....

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...
