You can start by modifying the Atom BBC MOS rom as this contains most functions (api calls)!for running BBC Basic. I was looking for the source but I could not find it. With a decent mod rom you can run BBC Bacis with no modifications at all.

That is the way Acorn implemented BBC Bacic on the Atom.

If you are going to source parts like this, it may well be worth letting your 'customers' know that they are recycled parts, just incase there are any problems with them. I will test them before shipping, as I program them in an already build Atom. So I'm sure that they are working when they leave ...

I think they are already indexing again: https://www.google.com/search?q=atom+2k18

Thanks for your feedback. I'm seriously considering this option. After all, the Atom is not a really life-saving or life-supporting device. Although I'd probably die without it

I also use (and advice) a 5V 2A usb adapter, bought in a local store.

Today I have played a bit with KiCad to make an adapter for the CPLD's but whatever I try, it's always too big. I really dislike the surface mounted devices because it's difficult to solder them and also difficult for me to program them for other people who will build an Atom but do not have access ...

Have you decided which board to use?

Not yet, the XC6SLX9-board is cheaper and can route the audio and video signals over the PCB which makes it a bit easier. I also have to look at the physical space that both devices need and how they fit on the PCB.

There are lots of these available, e.g. https://www.ebay.co.uk/itm/Xilinx-FPGA-Spartan-6-XC6SLX9-Core-Board/111640406811 (This is the board the Duncan referred to in the post above, that we are now using with ICE-T65) Can the video and audio signals that are now routed with a separate cable from th...

There are some adapters available, however IMHO they are quite expensive and you still have to solder them. The advantage of such an adapter is that you can easily swap the CPLD's: http://www.epboard.com/eproducts/parts/EPL-0044.htm The FPGA does much more than only the video, it has also SID audio,...

Are you thinking then that this would be incremental changes to the current design? I was wondering if it would be worth going for a 3.3V only design. I prefer an incremental change to the current design, however I'm not unwilling to use the XC6SLX9 Core Board if we can use that. It's only about ha...

Since I still receive request for an updated Atom 2k15 board I'm starting to think about an updated design. With the current we have some issue, regarding to components: The XC95xxXL in PLCC44 package are not available any more The used Godil is also discontinued There's a small mistake in the seria...

I had a very goood time as well. Thank you Kees for organizing this meeting again. And yes, I'm thinking about an update of the atom board. Atom 2k18 sounds good, doesn't it? Maybe our next Christmas present

I'll start a new topic soon....

Robert, can you pm me your FaceTime contact data? We’re ready to connect.

Have fun guys! Looking forward to see you today by a video connection.

I was at the monthly Atom User Group meeting this evening, so I didn't notice your post earlier. But the certificate looks fine to me, I don't think there's any improvement possible. Other actions could involve implementing automatic redirection from http to https and implementing HTST. But imho thi...

Roland - what system do you want to use for the video link? I prefer FaceTime if you have a Mac your end. Otherwise I can try to set up Skype, but it isn't something I have used before.

I'll bring a MacBook, so we can use FaceTime.

'your connection to this site is not secure' Does it also tell you why? I have no problems on my computer (FF and Chrome), nor on my iPad. However, a quick check on https://www.xolphin.com/sslcheck/stardot.org.uk says: The certificate could be verified and is installed properly. The root and interm...

Robert,

Are you bringing a laptop with beamer for a video connection to the TechSat meeting in Wijbosch - NL?

Seems to work fine on my iPad

Two other gdpr things: - SSL is required - data portability: please send me all my posts so that I can move my account to forum.acornatom.nl :lol: I tried to make use of my right to be forgotten at our national "belastingdienst" (tax authorities) but my request was denied :cry: Thank you Daniel for ...

The display looks great
If you zoom into the picture it looks like the vga connector is plugged into the wall

Looking forward to meet you Neil. Just bring something you're working on. Or just a good mood

That magazine looks very profesional. I hope that the Electron community provides a lot of input for it. Well done

I didn't know you were working of this. Looking forward to see it on a techsat.

Btw, shouldn't it be COLOUR 3

Just a speculation, without any investigation of the datasheets: can it be caused by #B002 changing during the execution of the ADC #B002 instruction?

The first thing that pops into my mind is a glitch in the cpu or hardware. Perhaps a memory read error (bpl opcode 0x10 instead of bpl opcode 0x30 which has only one diiferent bit). I didn't run the routine yet, but is there any difference on what type of real Atom you run this? Original, Atom2k15, ...

@oss003, @davidb, @Multiwizard, thanks! And nice to read that there are more dutch Acorn enthousiast here. :) Best regards, Erik Hi Erik, Welcome to this forum. I'd like to invite you for our annual techsat on the 2nd of June in Wijbosch. A famous village near Schijndel. It's very well known becaus...

Because 67% of the attendees wanted to start earlier, I changed the opening time to 10:00h ...... 8) Good job, as usual =D> Did you also contact the people that are not (very often) on StarDot but visit our meetings? Otherwise we seem to have only four attendees. The same weekend there is also an A...

I use the DISAS and STEP ( or TRACE ) statements regularly. They are in several expansion roms.
