I'm opening up my E-MU systems sampler ESI-32 to replace the dim LCD with an OLED. There have been different makes of the ESI-32 and its follow up models on the market. This is one of the oldest devices, as far as I know, you can tell by the separate SCSI-board. I've upgraded the machine previously with an internal ZIP-Drive and it also received the "Calamari" Turbo board extension back in the days.
