I'll fix that at some point next week, and publish the design once I've has a set come back I know is correct. Given the size of the boards, it's only $16 for 3.
I don't know if you are interested in taking orders for some bare PCBs when you next get a batch please, but I would be interested in 2 or 3 if possible? Happy to pay costs and postage.

My boards are here from JLCPCB.
30 dual Atari joystick to beeb and 10 dual megadrive to beeb adapters boards, shame I'm away for the weekend at Revival and probably won't get to build any.
boards.jpg
The mega drive ones support 1 button each or 2 buttons on one or with software support (see Warlords) 2 buttons on each or 4 buttons on one, selected with a switch between the ports.

The idea is that they can be built into a 37 way DSUB connector case and have a 15 pin dsub attached to the board (cutting off the excess case) to plug directly into the beeb or with a straight through cable (9 core Atari or 10 core Sega IIRC).
usage.jpg
The accuracy of the manufacturing seems good to my untrained eyes. The holes aren't blocked, despite what it might look like, but even if they were, they seem to have included a complimentary pointy stick!
accuracy.jpg
The total cost was just under a tenner, although that did take a bit of tweaking and using air-mail, which apparently takes 2-4 weeks (mine was 2 from ordering). Air-mail "small print" says that you are liable for postage back to them if it can't be delivered and is sent back to them!

Great work Tricky :) - I've been really happy with JLC! The price is outrageously good.

OOh. You went for the Gigatron. I looked at these but really expensive and limited what you could do with it at the moment. Maybe one for a later date.

It was pot-luck who got the red PCB. I had just one of those left.
The green ones are laid out with the connector the other side so
it doesn't need the extension.
There are no more PCBs (red or green) left now.

A PCB to allow me to test -8-bit podules in an Archimedes. (I don't want to wear out the connectors in my A3000)
IMG_20180519_163958301.jpg
(my first non-rectangular PCB!)

And some new 8-bit IDE podule PCBs, now with room to fit a DOM on the 44-pin connector, so no cables or adapters required.

Thanks to Retroclinic, yesterday I received this rather unusual beast:

Some very nice 4mation software. No idea if it works yet.

@Jonb. Toying with the idea of taking it with me to Abug South but dont think you are going to that. I plan to scan any documentation that isnt on www.swtpc.com (which is probably not much). I also plan to copy off all the floppys somehow to secure them.

I'm interested in seeing more of this too. It's in MAME but doesn't yet support floppies or software.

My interest is while my first computer was an Acorn Electron, before that I had been using one of these (I was about 7-10). It was my Dad's computer and suspect he bought it in kit form and built it himself, unfirtunately I cant ask him.

Still need to check but has all the usual monitor, text ed, assembler, tools. And of course Flex. I beleive it has basic and C as well but not checked yet.

A little bit off topic technology wise but it does mean I no longer have to look at this forum on my phone...

Virgin TV and fibre:-

I did a speed test and got 205Mbps! Even the upload is nearly 13!

I'm outside the area covered by Vigin cable. And was "too close" to the BT exchange for them to install fibre-optic cable... (don't know about now, haven't asked for a while...).

So am on normal broadband. Fast enough for my needs.

What is "too close'? We are about 100Metre from the exchange and have Infinity 2. Only 75Mbps (get about 50) although 17 Upload (get about 15). So Virgin seems to have slow upload for its download speed.

Lardo Boffin: how noisy is your VM box? I have one of those in my bedroom and it's distractingly loud, even when I'm watching the TV (it's turned off the rest of the time). I can hear a constant droning noise from a fan or the hard drive.

I will have a listen tomorrow but my hearing is somewhat compromised by too many Motorhead concerts over the years! Tinnitus tends to drown out most background noise. I’ll ask the kids - they will know.

I thought that when I did a few speed tests. My old Sky fibre was around 35 and 8 so a much better ratio.

To be honest would have been happy with that but our builders made a deal with the devil, sorry Virgin and its the only fibre available. Projected normal broadband would have been 4 to 8 which is not really good enough for when I work at home.

Virgin is properly reliable. Having done both, you don't notice the upload speeds being a little bit lower, but you notice the fact a family of four can hammer the connection without it flinching...

Virgin always have been tight on uploads, we used to find on the old Virgin 50MB/s sending mails with big attachemetns was always a pain. VDSL always is a bit (much) slower on the downloads but has better uploads. Long time before we will get FTTP out here in the sticks unfortuantely, will have make do with FTTC, its a hard life.

To be fair our VDSL is more reliable than our virgin connection was, used to be down for days. But then that is probably because we have business broadband now and being 100M from the exchange.

I suspect it varies greatly depending on what area you are in. And no virgin here anyway (as we moved away from cachement areas)

An Electron Turbo board, thanks to emeu1. This is a design from the Dutch version of Elector. Erik is also translating the article for me - I'll publish when I get it.

Link to the article in Elektuur

It looks like there's a few tracks that need cutting in the Electron :shock: so I may have to get my scruffiest Elk out to try this on.
