=== 8bit Printer Port in CPC Plus ===
In the CPC Plus, Bit 3 of [[CRTC]] Register 0Ch can be used as eighth printer bit. For compatibility to normal CPCs it might be possible to enable/disable , this feature can be disabled by a 'jumper' removing the 10kOhm resistor R30 on the mainboard(aka R130 in the schematic). See [[LK Links]] for more info.
