 If you intend adding an ABBA switch to the CPC, it's a good idea to make the modifications to the external floppy connector before you solder it to the PCB. If you have borrowed the floppy power connector and leads from a PC, then you will need to remove the yellow wire from the connector and move the red wire to the position where the yellow wire was, as Amstrad (in their infinite wisdom) decided once again to steer clear of unnecessary things such as standards.
-When all the components have been added the board will look quite a bit fuller and you should now have a 6128+ PCB in front of you.
+If you just want to be able to use an external drive as drive A (and have a drive with number switching) you'll need to add a wire link from pin 4 of the internal floppy connector CD04 to pin 9 of the external connector JD04, as explained in this diagram from [[Amstrad Action, Issue 91, Apr 1993|Issue 91 of Amstrad Action]]:

	Although most of the parts are concentrated around the bottom right area of the PCB, there are a few other parts hidden around the board that need to be added. R28 (Directly behind the analogue joystick port) tells the ASIC that the CPC has 128K instead of 64K. R55 (between the ASIC and first RAM IC) connects the NCAS1 signal to the new RAM. LR04 and C39 (above the 26way floppy header) are required to supply the floppy disk with power. C39 is the only passive component with poles. Make sure that it is soldered in the correct position, with the minus pole towards the rear of the CPC.

[[Amstrad_Action,_Issue_90,_Mar_1993\|Issue ninety]] covers the RAM components, and [[Amstrad_Action,_Issue_91,_Apr_1993\|issue ninety-one]] covers the disc components - high(er) quality scans of these sections are shown below (note that the wire link and C99 mentioned in the RAM map doesn't seem to be required) :
