Libretto Part Numbers
Memory
By far the most coveted upgrade for the Libretto. It took me buying another unit just to get this. There are several manufacturers who made memory, and here are the part numbers:
| Manufacturer | Part Number |
| Toshiba | PA2056U |
| Toshiba | NW2056U |
| Toshiba | PA2051UJ |
| Kingston | KTT LBT16 |
| Transcend | TS16MTL50 |
| Kahlon | KTOS50B |
Display
The display panel the Libretto uses is the Sharp LQ61D133. I am not sure if any other display units are compatible, but if there are, be sure to let me know!
Other Part Numbers
This is the 70CT part number reference manual. The scan is rather low quality, but hopefully it is large enough to make out the details.
