Yep, but the difference is minimal, perhaps when Kees has finished to build his new Atom he can tell.... :)

Thanks Wim, it's nice to hear that there is only a little difference.

@Mark: I'm going to order a few components at Farnell. Do you want me to order a set of the 64p A/B connectors for you? I can ship them with the Godil when it arrives.

Roland,

Since you mention the 64-way Atom interface connectors, do you know of a cheap source of the ribbon cable IDC sockets that fit them. I've just ordered a couple from Farnell (farnell no 9359990) and these are quite pricey (£9.10+vat). The PCB mounting plugs/sockets are a lot more reasonable though.

For your board I've ordered a 64-way BBC style latching header (farnell no 1106753) to see how that fits and so I can use standard ribbon cable connectors in the unlikely even that I need to attach something to it.

Cheers,

Phil Young

Today I have connected and tested the joystick input... :D

The Atom I did use for this project already did have a ugly square hole in the side of the housing so I used it for the joystick connector... (next to the red arrow in the picture below)

Wow ... lot's of posts to comment :shock:

@Mark: Ok, I'll order a set for you.

@Phil: At the moment I don't know a cheaper source. I can ask around in the local shops if they still have some. The price of a pair is indeed quite high. Not lol.

@Wim: I never tested the joystick interface. I have to search if I even still have a joystick :lol: But the interface is just a bunch of small tracks between the PIC and the connector so I never had any doubts that it wouldn't work. Besides that, I tested the individual ports when figuring out my AtoMMC failures.

Not to worry ! It's not like I have to buy a lot of them....

Hi Wim,

You have done an absolutely beautiful, dare I say, professional job in resurrecting that Atom. I love the tidiness of no loose wires projecting anywhere in view, the landscape of this project is perfect.

Though I don't have an Atom, I can certainly appreciate what has gone into this, what a wonderful explanitory thread....

Very, very nice job indeed.

Hi Ed, thanks for the big compliment... :oops:

I really adore the Atom Computers and his whole design, that's why splitting the Atom was for me the hardest part, luckily it was for a very good cause otherwise I would never do it... :(

Even now this beautiful project is actually over I am still trying to modify some little things, of course I will upload the pictures of it... :D


Greetings, Wim... :-)

Like I said a few little more modifications...

This time the speaker output SP1 and the wire attached to the pin 7 of the SD/MMC card... :idea:

The only thing left to do is the shielded cable attached to E1 and E8 of the GODIL... :)

I have to agree with the compliments: it looks as if nothing bad ever happened to the original motherboard. :wink:

In fact, it's like Acorn secretly updated the Atom shortly before being split up and sold off, and that the rare prototypes have only now started to appear from their top-secret Dutch hiding place. :lol:

I can see the Ebay headlines already: Ultra rare Acorn Atom prototype computer
Starting bid: £ 750.00 :shock:

It's really a very nice Atom. I'll order one too :lol:

Actually, you're right, something really good happened to the motherboard. It wasn't working, now it is and in pristine condition too.... first Atom to go on eBay at 1000 pounds starting reserved. :shock:

There is craft and then there is art.

You sir, in this one thread, have displayed a good portion of both.

Very nicely done.... =D>

If you ever want to connect that printer to your new Atom, just make a small interface with a 74LS244 like the original Atom had, and connect that interface to the 64p connector. The A-port of the via is available to the outside world.
