Well, I can't find a maker's name on the actual display, but the PCB and many of the chips (including those on the flexiprints going to the display glass) say 'Sharp' on them. I guess there were. Given that the module i have connects directly to the Logic B PCB, I guess that is the one the machine was designed to use. If the Epson display needs the interface PCB to provide the blanking signal, etc, it would suggest that it was hacked in for some reason. It would be interesting to know the serial numbers of machines with each type of display. Was it that the Epson display was used in early machines (implying the Sharp one wasn't available in time, so they had to do the kludge to have working machines), or was it that the Epson display was used in late machines (possibly the Sharp display was discontinued and they had to find a replacement) or what? If necessary I can take mine apart again and photograph it... Will do. -tony
