OBERHEIM SYNTH

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 minimumamount 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 displaythat’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 previousdisplay replacements that I’ve done (Korg Wavesation A/D, SDD-3300 TripleDelay), I’d say $50 to $100 USD.  On theother hand, as Daniel Forro said:I don't think price could be abig issue for somebody with defect display and not usable instrument. 4) Does color matter?  Should thereplacement be blue, for instance, or could it be any color?I’d love to see the colors asclose to the original, if at all possible.Probably if I had a Matrix 6 with a bad display it would be easier to makethe 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 thateventually they will decline or go out altogether.  In such case, having a replacement at theready would be a boon, assuming that others love their Matrixes, -6 and -6R, asmuch as I love mine.Hope this will smooth your decision-making processes a bit...Dave Garfield

     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.
