Esprit Sytems Inc. Opus 220 Terminal SM needed..

Hi guys, sometimes in the past I've reapired some OPUS 220 Terminals from Esprit Systems Inc, Melville NY for an other company. (I still have one left over that still works and I want to keep it for my 11/83) and now I have to repair another Terminal (some Siemens Device) where the original FBT is sold out everywhere. I'm now searching for the display schematic part with the FBT from the Opus 220 Terminal to look if I could transplant one from the new FBTs to the Siemens Monitor. Sure, I could do some reverse engeneering in the Opus Terminal but hopefully one has what I need already? Thanks in advance, Holm -- Technik Service u.
