Serial Number of HP Palmtops and Proto Units

[Csaba Tizedes]

My question from this topic:

"Where can I found same information about 200LX and 95LX (or other palmtops)?
I have a Made in USA 95LX with ABA3107A00064 "PROTO UNIT NOT FOR SALE" and "57" marking on name engraving field."

Where can I found this information (yes, I Googled - maybe this is hidden deeply inside the DarkWeb )
How these SR No.s are built?
What does it mean "Proto Unit"?
If I have one and marked "57" what that number means?
Proto Units are the earliest units or sometimes few proto unit "generated" when the manufacturing technology is changed or moved to other place?

Thanks!

Maybe this kind of topics is a taboo on this site?!
BTW: I found an interesting table on palmtoppaper. Is it available in better quality?

Thanks!
