HP-25C Eumulator

[Didier Lachieze]

Many thanks Jose for this comprehensive NP 25 document !

Just a few comments:

• page 3, in the setup section, you can add the link to the video showing the various start-up modes
• page 4, the note at the bottom of the page talks about the HP 33 and 25 ROM selection but it applies also to the 21 ROM,
• page 6, for the V3 kit parts listing, the 74hc164 and the on/off switch are missing, there should be only one 100nF capacitor and the CR2032 battery holder comes mounted on the PCB,
• page 21, the battery holder section is not relevant for the NP 25 kit as Chris provides the battery holder already installed on the PCB.
