I already asked earlier in this thread but just in case :
Can you please add me for two build boards ? One with analog and one without (for my bbc and for the spectrum).

Thank you so much! Johan

I've received a new batch of boards so will be sending them out over the next couple of weeks.

These new boards are 12 bit capable so can be used with sources like Commodore Amiga, Atari ST and BBC NuLA however that means picking up the 12 digital bits internally from each of those sources so some soldering is required. (BBC NuLA untested so far)
Although the new boards are 12 bit capable, in order to bring all 12 bits to an external connector an extender board is required and that is fitted in the same way as the analog board.

Updated prices:
RGBtoHDMI
Kit: £25 (Only 2 through hole connectors left to fit and a cable to be made up - all other through hole and SMD components already fitted)
Built: £30 (Including cable)

Add-on Analog board:
Kit: £22 (All surface mount components are already fitted, only through hole parts have to be soldered)
Built: £25

12 bit extender board
Kit: £4 (only through hole parts)
Built: £7

Here is the list of users that requested boards so far

Kit:
SpaceFlightOrange 1x RGB + 1x Analog
1987akaTheMoneyPit 2x RGB + 1x Analog
marcusjambler 1x RGB + 1x Analog
rodders 1x RGB + 1x Extender
chrissawer 1x RGB
noggin 1x RGB + 1x Analog
Pepperm 1x RGB + 1x Analog

Built:
sdhip 1x RGB
mlouka 1x RGB
sixedup 1x RGB + 1x Analog + 1x header
CommanderCoder 1x RGB + 1x Analog
Mince 1x RGB
sota 1x RGB
BillCarr2005 1x RGB
roobarb! 1x RGB
nelgin 1x RGB
sjo03 2x RGB + 1x Analog + 1x header
Richard Hallas 1x RGB
tarcus69 3x RGB + 1x Analog
ryanm 1x RGB
Rod C 1x RGB
chris-uk 1xRGB
Bitstik 2xRGB

Can you please check I have your reservation above correct and also those that didn't specify kit or built I've assumed built unless you post an update.

I'll be including a 40 way GPIO header with the kit version so you can buy the cheapest Pi zero with no header and solder that in. I won't be including that as standard with the built ones as I assume you will be buying a Pi zero with header but if anyone does want one let me know and I'll add one.

Hi Ian, confirming that you have the right order for me. I already have a spare headerless Pi Zero so if you could add a header to my order that would save me sourcing one.
Many thanks!

Hi

I would love the 2 board solution, I have many Pi zeros. How do I go about getting them ordered please?

How do I get my hands on an RGB to HDMI adaptor please? I see that there are some for sale in Australia but I am in the UK...

Regards

Mark

I would love a kit for the 2 boards please. I’ll settle for pre made if you have already made them though.

Could you please include one header ?

Thank you again!

Yes, please — definitely still would like one! Thanks again — both for making these and your continued work on the software.

Just to confirm: I'm hoping to use it with a Commodore 128's 80-column RGBI interface — I think for this I just need an RGBtoHDMI board itself and no extra boards, is that right? The only other board which would be help me would be a buffer board, I think, which I guess there's not much demand for!

The 12-bit board doesn't help me, I assume? I can't find mention of what that supports, but I assume it's only for things like Amigas and STs?

Hi Ian

Could I go for an RGB + Analogue board in kit form please? (I'm down for RGB only built at the moment)

Thanks

Any idea if this will work with Apple IIgs RGB? It is kind of CGA-like.

Ian, any ideas as to when and how we will get details for payment and shipment please? I keep checking what I think are my messages in this board but am not seeing anything. Maybe I’m looking in the wrong place for a PM.

It might work. I had a quick look at the schematic and it uses 12 bits per pixel similar to the Amiga but it also depends on the resolutions and pixel clock rates. The 12 bits are available internally so you would have to pick them up in a similar way to the Amiga and Atari. I am looking at doing a new 12 bit analog front end which would mean a simple plug in solution for all those systems but it might not be possible as it would depend on the linearity of the DACs and ADCs to reliably extract the 12 bits noise free.

Should be in the next couple of days for kits. They will be going out first as I have to finish building the others. I'm not sure if it's the default but you can configure your profile so you get an email when a PM is received. (It's in "Edit notification options" under "Board preferences" in the user control panel)

Sorry Ian, not sure if I need the 12bit extender for use with a BBC NuLA now. Re-reading your post it sounds like its only to bring the 12bit video out to an external connector. Can you confirm please. If not needed then take the extender off my order. Thanks.

Yes you will need the 12 bit extender for NuLA (assuming it works as it's untested at the moment). The 12 bit boards have the same 8 bit header as the earlier 8 bit boards with the extra 4 bits on another header as there isn't enough room for the full 12 bit header so the extender consolidates this onto a single connector. Plugging a cable into two separate connectors would be awkward and unstable as the 4 way connector is not designed for cable connection so going via the extender is the only practical way.

Yes, you would need to make up a cable with a 12 way IDC plug on one end and a 9 way IDC D-type on the other (wires 1, 2 & 12 not used)

Kit received thanks Ian. Now to construction... I have to say that its a bit of a challenge to work out what does and doesnt need installing and connecting. I am reading through the Wiki and have no idea what P6 and P7 on the 3/4 level analogue board are for, not to mention any of the jumpers. Am I missing so very obvious construction guide or something?

Fit Long ends of P6 & P7 into pcb same as P2 above, then cut off the other ends of the pins at the plastic. They are intended to act as feet resting on the camera connector to stop the board making contact with the Pi zero.

After looking through the Kit assembly notes on the Wiki, do I fit the 4 pin socket into P5, biased to the end with the P5 lettering, then plug into it the P2 pins from the analogue board?

Update.... I have read the Assembly instructions now so the text above (dont want to delete because I was told off before) is completely superfluous. Sorry.
