HP-100LX
**********

Production of the HP-100LX began in mid 1993 and the release was in 
early 1994. 
Several improvements were made over the HP95LX. One of the most 
greatest was a full CGA screen with 640X200 resolution, 80X25 characters.
This meant that it was far easier to find MS-DOS sofware that would run
and display correctly on the unit. 

The Serial port was changed to a 10 pin proprietary connector that was
closer to a full RS-232. The voltages were lower than a normal RS-232 
port, but most devices could be used without issues. 
There is no connection on pin 10. The other contacts have the same pinout
as a standard DB-9 Connector.

The PCMICIA Slot was now changed to a PCMCIA (Version 2.0) which allowed
use of PCMCIA Modems, PCMCIA to Compact Flash adpters which expanded
the storage capacity to 64 MB.
