I've found that Epson's QX-10 CP/M 2.2 R2 will not boot on a QX-16. Reports not compatible with the BIOS version. The later R4 works perfectly on the QX-16 and has a M: drive made up of the extra RAM installed in the QX-16. I've not seen a R3 version of CP/M and so don't know if it is compatible with the QX-16.
