PB Legend 301 CD

Can anyone tell me where I can get manuals for the PB Legend 301 CD desktop...it's a 66 MGHz Pentium. I would specifically like to have the layout of the motherboard architecture, and info on the expansion cards that came with the basic model. I do not believe that anything has been done to this unit beyond adding an 8 mg SIMM to upgrade the RAM. I am hoping to extract the tape drive and add another 540 MGHz HDD to make the overall HDD capacity at 1 Gig. Hopefully upgrade the RAM to at least 32 Meg and upgrade the modem (currently a 14.4). Any info would be greatly appreciated. I have plenty of numbers off the motherboard but do not know which one are important to my search...I am just starting this training and am taking baby steps .The OS is Win95 upgrade on top of Win 3.1. Thanks to all who cam or will help. Strider
