I am now ready to accept orders. I want to make sure that people are clear about what is on offer (as some PMs I have received suggest I may have caused confusion). There are two options:
OPTION 1: PCB and chipset
You will receive a PCB and the two Yamaha ICs. You will have to source all the other components. You will then have to assemble the board. This (obviously) involves soldering.
Price for this is £7.00 including 1st class post within the UK. (Alternatively, you can pick it up from me at an event for £5.50.)
OPTION 2: Complete kit
You will receive a PCB, the two Yamaha ICs and all the other parts required for a standard build. You will still have to assemble the board. This too will involve soldering.
Price for this is £13.50 including 1st class post within the UK. (Alternatively, you can pick it up from me at an event for £12.00.)
Just to be clear, both options involve soldering.
In addition to the above you will need to source a 34-way female to female IDC cable and a 5V DC power supply with a 2.1mm barrel connector. (Pretty much anything will do as it only draws 30mA. I use a USB phone charger and an adapter cable.)
How to order
Please send me a PM with details of whether you want a complete kit or a PCB and chipset. Please also give me details of where you want it posted to. Please could payment be by PayPal 'friends and family'. I will reply with details of my PayPal registered email.
If you would rather collect this from an event, please still send me a PM with details of whether you want a complete kit or a PCB and chipset and which event you want to collect from (RISC OS London or ABUG Bolton). I am happy to take payment by PayPal now, but I am equally content to take cash at the event when you pick it up.
I hope this is all clear and OK with everyone.
Finally, I am still looking into a solution for anyone who is uncomfortable with soldering and, therefore, wants a ready made card. I hope to post details of this in the next few weeks.
===================================================================================
A small number of people have asked me whether they could have one of my BeebOPL boards and I thought it may well be worthwhile checking whether there is any wider interest.
I would make these available at cost. Depending on the extent of interest, I think one board together with the two Yamaha chips would cost about £6 or £7. All the other parts are readily available from the usual electronic component stockists. If there were sufficient interest, however, I could also buy the parts in one go (thereby avoiding additional P&P charges). If I did that, I suspect that a complete kit of parts (including the board and the two Yamaha chips), with sufficient numbers, would cost about £14 or £15. The only other things necessary would be 5V power and a 34 way IDC ribbon cable.
The card is based on the YM3812 which was the chip in the Ad Lib Sound Card and the first Soundblaster card.
I have put together a playlist on SoundCloud which demonstrates what the board is capable of. All the recordings are made directly from the audio output of the BeebOPL board.
For fans of badly written code, there is also a GitHub repo.
My original thread on the board is here.
Here is a picture of the board. As you can see it has a very similar footprint to the BeebSID board.
Programming it is rather different from the BeebSID though and I am also hoping to put together a few notes on what I have learnt so far.
Finally, this YouTube video may be of interest. The Sound Expander was very much the inspiration for this project.
So feel free to post here or PM me if you have any interest in this.
I am also hoping to demo this (along with some other sound related things) at the upcoming RISC OS (& ABUG) London Show at the end of October. So do come along if you have time and are nearby.
This is not an order list. It is just for me to keep a record of who has expressed an interest.
