Just a comment in reply to many questions received:
- New calculators still come with the old firmware (here and everywhere else!). These are still available. They do not come with cable unless expressly stated (as below)
- We also offer the "Enhanced version" that comes with the new firmware installed + cable + HP16c overlay. We also check the keyboard for malfunctioning keys. It takes out the hassle of installing it oneself.
- Cable can be bought separately. There are lower prices for HP15c customers from The Calculator Store. For American customers, it can also be found at commerce.hpcalc.org
- there is a bundle with cable + hp16 overlay too
- The new firmware fixes also the DEC bug. We just do not comment unsupported features...;-)
- Backup or restore does not reset the machine and does not require pushing the cable buttons. However, restore alters the memory contents. NOTE: restoring a file made in a different mode (15, 15.2, 16) may (will?) result in errors, and that may require a reset.
- If the HID connection does not seem to work, please try another USB port - some work and some don't!
