HP-71B CMT Card Reader Memory Module Internal
I am currently writing the card reader memory modules section of the HP-71 Compendium
and to my surprise the internal component of the only CMT-CR module that I have was made by HHP.

Are the card reader memory modules sold by CMT was actually made by HHP ?
At this point I assume that my module is either a prototype, a case switch, or whatever.

Can somebody in this forum who has a CMT-CR module can validate who made the internal of his module.
It's pretty easy to verify, just remove the side tape, the module open up in two parts and you can see on the PCB who made it.
If it's HHP, you should see "HHP inc." on one/all of the PCBs, for CMT well I it's for you to tell Wink

Thank you!

Sylvain
