Changes

* Another 664 version, found in german Schneider CPCs (though it but might be also used in other countries?)* This board version typically includes a small patch: A resistor soldered between Pin9 (A0) and Pin14 (/CASADDR) of IC105. The patch is also seen on [http://amstrad.cpc.free.fr/amstrad/cpc664_e.htmhere]. The resistor has no "R3NN" number is labeled as R160 in the schematic, but isn't labeled on the text layerPCB, so it was apparently added after designing the PCB.
