Hi Bob and other Oberheimers,
In response to your inquiries about the form(s) of the Matrix-6/-6R displays, I thought I'd throw in my tuppence, albeit a bit late...
1) Does the replacement display need to fit where the other one was, even if that means having to de-solder the VFD
A replacement with a minimum amount of fuss or modification would be the best.
2) If not, then how/where is the replacement display mounted
Nahhh; let’s try for a replacement display that’s at least to the same size as the original.
3) What would be a reasonable target for the cost of the display
Uhh, judging from the previous display replacements that I’ve done (Korg Wavesation A/D, SDD-3300 Triple Delay), I’d say $50 to $100 USD.
On the other hand, as Daniel Forro said:
I don't think price could be a big issue for somebody with defect display and not usable instrument.
4) Does color matter
Should the replacement be blue, for instance, or could it be any color
I’d love to see the colors as close to the original, if at all possible.
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.
Me too – but I’m betting that eventually they will decline or go out altogether.
In such case, having a replacement at the ready would be a boon, assuming that others love their Matrixes, -6 and -6R, as much as I love mine.
Hope this will smooth your decision-making processes a bit...

So would an HD44780 compatible VFD take up less space than a backlit LCD

Maybe it's not necessary to interface to T6963 (and compatible) standard, that's for graphic displays.
For Matrix 6 character display would be enough good, this is HD44780 standard...

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.Interfacing Toshiba T6963C LCD to Atmel AVR microcontroller
