GEM HP Palm Computer

I am looking to find a working, or repairable HP Palmtop with the Insight GEM software on it. I wanted to track some trends on my rear engine. I plan to replace the engine monitor in the spring, but for now, need to download info. Anyone have any leads or ideas?

I called insight, they say they no longer have or support, so the manufacturer is no help. I have found an HPLX but no joy on the GEMCOM software, if anyone has, well that would be great. It is likely a PC-CARD that installs into the HPLX - I can copy if some has one they can share.

Please let me know.

I poked around and find it odd that there is not a copy of gemcom.exe out there.

What analyzer are you going to replace the GEM with?

Frank,
I have the GEM software! It’s present on a memory card that plugs in to the HP 95 or HP 200. Do you have the adapter that allows you to use the memory card with your HP?

Hp and Gem

So I would love a copy of the software. You can email me with info. Frank.oconnor19@gmail.com

I was thinking about going one of three ways. A G4. Basically nothing more then what I have, but up to date on displays and software. A jpi960. Replace all of the legacy engine monitoring systems or a garmin EIS as I have all glass for flight systems

Each has a progressively larger price tag. Lol

Do you need the functioning HP or do you have one?

Gemcom.exe

I did not get it. If you are sending as gemcom.exe lots of email systems will stop that. If you have a chance call me. 917-648-3839

Success!

Thanks to a little field engineering, and some luck I now have a working HPLX 200 palm computer, with a working copy of GEMCOM on a compact flash card. I was able to get it formatted so it can be read in both my windows 10 computer and the HPLX for the interface to the GEM1200. Clearly this is not a modern solution, but the data is there and with a little experimenting I found the spot where I can hold the computer to get the interface to work. There is a reason that IRa interfaces did not catch on, they are very temperamental.

In any case I was able to unload data and graph it on my computer. showed some interesting results, confirmed what I suspect is a bad wire or fouled plug in Cyl1 rear engine, I am posting screen shots of CHT, EGT for both front and rear from my last flight, would love some feedback from the group. Thanks in advance.

You will notice a decline in temps and then a rise and decline towards the end of the flight. I executed a go-around as it was a new field, short runway so I did a fly over to check it out.

Nice work recovering the data! Yeah, probably something related to a wire or plug.

Below is from Things That Effect CHT"

"Failure of one spark plug or magneto can also affect CHT, because the air-fuel mixture takes longer to burn when it is ignited by only one spark plug instead of two. This causes θpp to occur later and CHT to decrease".
