HP 01 WATCH MODULE REMOVAL Message #1 Posted by RICK ROAT on 2 Oct 2005, 10:34 p.m. ANY HINTS OR EXPERIENCES ARE WELCOMED!

Re: HP 01 WATCH MODULE REMOVAL Message #2 Posted by Eric Smith on 3 Oct 2005, 4:38 p.m., in response to message #1 by RICK ROAT I don't know how to do it. But if you're replacing a defective module with a good one from another watch, I'd really like to acquire the defective module for reverse-engineering purposes for Nonpareil.

Re: HP 01 WATCH MODULE REMOVAL Message #3 Posted by Bernhard on 4 Oct 2005, 4:47 p.m., in response to message #2 by Eric Smith Oh yeah, don't throw anything away. I've just bought a brand-new $72 microscope including PC camera (presumably made in the Ukraine of ex-Soviet union fame, the camera possibly made in China), and I'll try to make chip photos of a 1820-2028 for reverse engineering). These are the moments I regret to have resigned from the job in the old company... but this failing countries' socialistic taxes and social security made that $120k/yr job absolutely noneconomical in terms of net income. Now I must do all those neat chip photos myself and pay for the equipment myself... Bernhard

Re: HP 01 WATCH MODULE REMOVAL Message #4 Posted by RICK ROAT on 5 Oct 2005, 6:19 p.m., in response to message #2 by Eric Smith If you want to make an offer for the module or the complete watch, please let me know. Thanks, Rick

Re: HP 01 WATCH MODULE REMOVAL Message #5 Posted by Eric Smith on 5 Oct 2005, 11:37 p.m., in response to message #4 by RICK ROAT I'm certainly willing to make an offer, especially if it is non-functional. I want a non-functional module to tear apart for reverse-engineering (photomicrograph the ROM chips), in order to add HP-01 simulation to Nonpareil. I'd rather not destroy a working watch to do that, and I can't justify paying the price of a working watch.

Re: HP 01 WATCH MODULE REMOVAL Message #7 Posted by RICK ROAT on 11 Oct 2005, 5:17 p.m., in response to message #5 by Eric Smith Eric, If your $250.00 offer stands, I accept, please let me know your address and mode of payment. Thanks Rick

Re: HP 01 WATCH MODULE REMOVAL Message #8 Posted by David Smith on 4 Oct 2005, 5:56 p.m., in response to message #1 by RICK ROAT If I remember right there is a retaining ring that secures the module. And another one that secures the keyboard. I believe that they are threaded in different directions. Also they are not solid rings, but have a small split in them.

Re: HP 01 WATCH MODULE REMOVAL Message #9 Posted by RICK ROAT on 5 Oct 2005, 6:16 p.m., in response to message #8 by David Smith David, You are correct, this watch is built to last, sometime it was submerged and corrosion occured in small amounts. Thanks, Rick
