More k2500 questions

I'm still trying to understand and setup my new (used) K2500.  As I said previously, I have my old (not powering up) K2500 and I believe everything that goes with it.My new keyboard shows programs from 1 -199 and then it starts again at 750.  When I bought my original keyboard I  had more programs installed in it then I believe I have in this newly purchased keyboard.  I believe I have all the  floppy disks from my original keyboard purchase.I would like to understand this better and possibly install those programs that I'm missing in the new keyboard.  Problem is I'm pretty much ignorant about most of this and when I try to do something that comes fairly easily to others, things go way wrong for me.So if there is someone who would be willing to guide me along with getting my keyboard upgraded I'd be very happy.  I am scared to death that I  will do something that will render this new keyboard useless.For starters here's a list of floppy disks I have but don't know what they are for and how they should be installed.  I appreciate all feedback and help.Don.....Operating System Disk	(RED)	OS Version 2.52 K25V252.KOS			      2.80 K25V280.KOS (X2)Operating System Disk	(BLUE)		2nd Disk	Version 3.12 OBJP312.K25	/ 3.32	Filename OBJP312.K25		/ OBJC332.K25	For OS Version 2.52		/ 2.52Factory Objects Disk	Rom Objects Version 3.12	Base + Piano OBJ0312.K25	Rom Objects Version 3.22	Base + Piano + Orchestral OBJ0322.K25ROM Objects Disk (Base + Piano + Orchestral)	Version 3.22Filename OBJO322.K25For OS Version	2.52ROM Objects Disk (Base + Piano + Contemporary)	Version 3.22	Filename OBJC322.K25ROM Objects Disk (Base + Piano + Contemporary +Orchestral) (X2)	Version 3.42Filename OBJF342.K25For OS Version	2.52Accessory Disk	Orchestral ROM Program Farm & Demo Sequence		ODemo25 (dir)		OFarm25 (dir)	Piano ROM Program Farm & Demo Sequence (X2)		PDemo25 (dir)		PianoFRM.25	Contemporary ROM Program Farm & Demo Sequence		CDemo25 (dir)		CFarm025 (dir)Sent from my Galaxy Tab® S2
