[Motorola] Saber info

[Glenn Little WB4UIV]

I picked up the following Saber radios at a recent hamfest.
Can anyone point me to the correct service manuals for these?
The secure modules have been removed.

H43YXN7139CN H99QX+052H  12 channels
H43QXN7139CN Securenet-S 12 channels
H43YUN5170CN Systems Saber with Securenet-S 16 channels
H44TUB5170CN H99QX+143H Systems Saber with Securenet 16 channels

Any help appreciated.
These model numbers doe not completely decode withe the information I 
can locate on the web.

Thanks
