Hi all, There was a post in one of the Facebook vintage groups from someone who has Epson QX-10 Q10CMS and Q10GMS boards. The GMS is what I have in my own QX-10, but does anyone know what the CMS board is? Both boards have a NEC 7220 graphics controller, but the CMS appears to have more on-board memory (384KB vs. 256KB). On the other hand, I'm not seeing any on-board ROM in the photo of the CMS, unlike on my GMS. cheers, Jules
