I've now started to build an enclosure for mine.

If you have seen the episode of the IT Crowd with the internet in a box - mine looks a lot like that. :o

To save wading through the last 18 pages (I did go through the first 3) can someone give me a price and availability for one of these?

Mine is now boxed - but easily opened to see the BeebSID in all of its glory.

(I need to protect it - I would be distraught if it broke.)

Ok,

Just prototyped the 2.0 board though I did manage to kill one of my two spare SIDs in the process :( I've discovered a couple of problems with the board as built, main one being that I didn't make it quite wide enough so was only able to get one of the bus connectors on it but that for me was not a problem. I have fixed this in 2.1. I've also added a set of pads for the poly caps that Maplins do as they are much smaller than the ones from the original board.

I've not included the MOSFET (yet), as the board now has sockets for both 12V and 5V-gnd-gnd-12V (standard 3.5" floppy power connector). I could add the MOSFETS but I assume that I'd want to put two of them on there, one for each of the 12V lines.

How does this sound to people.

I may be prepaired to do a small run of boards, but it would be just that, the boards will have to cost things but would I imagine be a similar price to the mk1 boards.

Here's the new layout.

That sounds great :D There's not a possibility of a header of some sort for audio in/out and the ability to use audio out on the 1MHz bus into the SID is there?

Sounds spot on. Will it play with an 8580?

There's a jumper for audio to bus, just behind the phono out connector, top left, there's also a 2 pin 0.1" pitch audio out connector here too. No Audio in currently, but should be easy to plonk another 0.1" header on for that.

@danielj it should play ok with all versions of the SID, as the board has a jumper for SID VDD either 12V or 9V, though note I have not tried this as the SID I have is a 6581.

Cheers.

Ok pictures of the latest prototype here :

Layout :

Things of note :

The board may be powered either via a +12V supply, or via the 3.5" floppy power connector.

I have put the FETs on the +12V and +5V inputs, this will prevent damage by reverse polarisation, however this will not prevent dammage from plugging the floppy style power connector in upside down ! Which would route the +12 onto the +5 line and vice-versa. You are strongly advised to use a polarised connector to prevent that !

As a side note does anyone know where I can get 3.5" power connectors from ?

I have added a jumper to allow the option of selecting +12V or +9V for the SID.
I have added a jumper to select +5V provided by the regulator or from the floppy connector.

I have added a connector for audio in and brought the potx and poty SID pins to a header.

I have reduced the capacitor footprint to that used by the Maplin parts here : http://www.maplin.co.uk/polyester-pet-f ... tors-98159 as the y are smaller, if people really want I could possibly squeeze the large format parts on too.

The board has had a complete build and is hand buildable, once I'm done I'm going to make the Eagle files available so people can build their own if they want to. but as said before I am going to get some professionally made.

If there are no problems with this board once tested and there anre no further requests for things to be added this will be the version produced.

Cheers,

Phill.

As a complete aside, it appears we have two friends in common on Facebook, Bryan Jackson and Justin Murdock with whom I worked when I was contracting for Pipemedia :D

I have a spare set of logitech 2.1 x240 speakers which should do this wonderful little device justice.

Not sure my neighbours will be too happy though listening to the Castle Quest tune with full bass :lol:

The 3.5inch floppy 4 way power connectors are just a modified 4 way, 2.54mm (0.1 inch) pitch right angle PCB connector and matching crimped 4 way housing for the cable connector (but you can solder the crimps if you do not want to pay silly money for the crimping tool).
So these may work (have not tried these, but have tried a different brand in the past with no problems):
http://www.rapidonline.com/Cables-Conne ... ader-66416
http://www.rapidonline.com/Cables-Conne ... tors-66414

Maplin do the proper cable connector (this may, or may not fit the PCB connector listed above):-

If you keep looking, I'm sure you're find the "proper" PCB connector... :mrgreen:

And as your board looks so good =P~ you can put me down for one as well :D

Funny you should say that my Beeb aux power -> floppy cable was partly salvaged from a dead PC PSU.

In all seriousness this http://uk.farnell.com/te-connectivity-a ... dp/1056115 looks like it might work.
