OBERHEIM SYNTH

I would concentrate on the adapter board itself first and allow the end user to decide on the LCD arrangement. There are other synths with similar requirements for a new display like MKS-70 I think?
Make a board that converts the Matrix 6 display format to something like T6963C for instance (if this is how you were thinking abut doing it) then you may find that some of the work (one half) has already been done. As an example I found this....but I have no idea how to do anything like this myself.

     I'm glad you still consider it and work on substitution.

Hi,
   I am having some trouble getting started with this project.I think writing the code to map the serial data to a std LCD willbe the easy part.   What is giving me trouble is trying to make the 
decisions for other people:
1) Does the replacement display need to fit where the other onewas, even if that means having to de-solder the VFD?

That would be good, anyway when the old display doesn't work it should go out of the machine...


2) If not, then how/where is the replacement display mounted?
3) What would be a reasonable target for the cost of the display?Probably a small pcb will be needed to hold the conversion circuit.

I don't think price could be a big issue for somebody with defect display and not usable instrument. So whichever reasonable price you ask people in the need would pay...

4) Does color matter?  Should the replacement be blue, for instance,or could it be any color?

Blue is nice and fashionable, but to me color is not important. It should be well readable with enough brightness and contrast. 


Probably if I had a Matrix 6 with a bad display it would be easier to 
make the decisions, since I would have a real need.   I have both a 6 and a 6R,and both displays are fine.
I have looked at displays on the web several times.  Some graphic thatwould allow emulating the original characters on the Matrix 6, and otherssimple character-based displays.    It's not all that easy finding something 
that will fit where the existing VFD is, that is also backlit.    But I thinkthere are some out there.   I found one that looked nice, but it's from Taiwanand they have no USA distribution.
   Anyway, I am still willing to follow through on this, just trying to get 
the requirements better defined.
     Bob
