Xpantastic!

Hi,

I'm new here, so perhaps I should introduce myself. My name is Steve 
Lenham and I run a small design consultancy in south-eastern England, 
an increasing part of which involves working on classic synths and 
related equipment.

I recently restored an Xpander and, amongst other things, its owner 
asked me if anything could be done about the failing vacuum-
fluorescent displays. As a result, I designed and produced a 
replacement display board fitted with three Itron DN4015 displays and 
wonder whether it might be of interest to others here.

Full details can be found on my website:

www.bendentech.co.uk/sound/obvfd.html 

Unfortunately it would appear that Japanese-made synths use a single-
piece display/panel PCB, so aren't compatible with this upgrade. Can 
anyone tell me what proportion of units were made in Japan?

Initially I am looking for a small number of technically-competent 
beta testers for the upgrade to confirm its reliability. They will 
get a nice discount in return for their feedback. UK-based testers 
would be preferred for logistical reasons, and I would particularly 
welcome Matrix-12 owners since I would like to establish any relevant 
differences.

However, do please also let me know if you would be interested in a 
production board - I'd like to know whether this is worth pursuing!

Best regards,

Steve Lenham
