I've seen a connector on eBay that's suitable for a Minus One pcb,: https://www.ebay.co.uk/itm/Acorn-Electron-card-edge-connector-48-way-2x24-with-keyway-0-1-pitch/402542272306?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 That one is a regular - keeps popping up - just when you ne...

And well done with the Minus One build

How would you send a text message to the Space station from a BBC Micro.

You wouldn't use a BBC (!) when you have an Electron with WiFi

Hi, I am looking for 2 or 3 WD1772 Floppy Disc Controller ICs for an A3000 and an A540. Does anyone have any stock, I can only find suppliers in China online and would prefer to get from a known good source if any one has a few they could spare? Try Mark Hasman at RetroClinic or Steve Picton at IFE...

Hello All, Looking for a Acorn Atom. Was my first real computer (back in the days when I was a youngster) and I would like to start some hardware projects for this computer. Maybe someone has one extra laying around (not using it) and would like to sell it to me. Kind regards, Edzard Eindhoven - Th...

Hi Dave,

If you still have any of these available, I would like to order one RAM cartridge with case please.
I am unable to PM you. Thanks

Nice design . . . Worth every penny

Looks like it could have the ADFS ROM in there as well?

Dave, You're a bit far for me to collect. Curious as to rough costs for shipping of the scopes. Stephen Sorry, I should have marked the Yokogawa as sold (now done). The Philips PM3055 50Mhz 'scope is under offer, however, when I did a pre shipping test it had died with a dead power supply and I'm c...

All ULAs will work in all Electrons . . . And then you'll have a spares board

Dave H.

CJE have them although not cheap: http://www.cjemicros.co.uk/micros/individual/newprodpages/prodinfo.php?prodcode=VAR-A3010PSUTR1 Might be worth asking them if they'll do a deal or have any junked A3010/A3020 PCBs that you can salvage the transformer from... Insurance claim? Or wasn't it insured :s...

Yes, it's a shame about the memory decisions and lack of mode 7, but I always thought the Electron with the plus 3 really looked the part! Seconded . . . and it had the disc drive, of course. With a MRB added - well . . . :D Buying the system was a little like HP e.g. you didn't have to fork out al...

I can't understand why people pay so much for these things, emulators are free and better...

I can't understand why people waste their time with ugly emulators when genuine hardware is still available.

The problem would be software support. It'd be a major job.

Maybe someone else could handle this . . . ?

Dave H.

Just a thought . . . ACP produced both a DFS and ADFS E00 for the Electron. DFS was as JGH described above e.g. RAM was overlaid at the top of the 16K block for its workspace, however, ADFS E00 used a second 16K bank within an ABR cartridge. I believe both could be "PLDed" e.g. use a PLD t...

Any news on the scope? I found a Service Manual for it, as last. I'm still trying to find any sign of where failure is, however, it's been reported that the caps can sometimes be an issue. So I've decided to re-cap the Power Supply board - which is going to take a while - there's a few of them! Dav...

Is there a Gotek firmware for the Yokogawa? :wink: Sorry, absolutely no idea on that one. IIRC it's a non standard fitting e.g. it doesn't have a dedicated front panel . . . So fitting one one may be an issue, unless there's an external connector? If there is one, maybe an HXC Floppy Emulator would...

Hello

I've purchased an A310 and would love to add a backplane to it, if anyone has one for sale? Just a two port would be fine although four port considered

I'm located in the UK

How many 4164s do you need? I have 6 and can test them . . . They might not all be new!

Dave H.

The circuit can be found here - a bit fuzzy but readable. And it specifies 4164s so it looks like your good to go.

thanks for the link Dave, but that was for the Model B (16kb x1), I am looking for B+ replacements (64kb x 1)

Monday morning, the 11th January 2021. Mrs H. informs me she can't access the internet (in a grumpy voice :roll: ). I verify the no internet issue and do the usual - switch-off the network apparatus and then switch on again . . . 10min. later, still no internet. OK, I say give it an hour or two and ...

Looks in good condition . . . it all depends how much you're willing to spend on you A3000? At the moment it's at £100 - so may be worth a punt! A good time to buy, just after Christmas . . .

Keep us informed on you venture and its outcome . . .
