I'm considering replacing this 16x2 LCD module found in an early '90s E-Mu synthesizer with a modern OLED equivalent.
However, apart from the Solomon name I can't find any reference to any of the markings online anywhere. The only other identifying marks are "AC358 REV.A QIS 1793" on the 14-pin ribbon cable.
Dimensions wise, the Winstar WEH001602C range (at 85mm x 36mm) appear to be a perfect fit and are supposedly (mostly) compatible with the HD44780, but without the pinout of this board I can't tell how "plug and play" it might be, or indeed if it's even possible.
FOLLOWUP: The WEH001602C was indeed completely compatible with my E-Mu Proteus 1 range of modules and the E-Mu "Vintage Keys" module. I did find however that it would sometimes fail to initialise when installed in a later Proteus FX model. It was however slightly thinner so I designed and printed a 3mm thick standoff to bring the display bezel out to the correct position.
