Various HP41 equipment for sale [UPDATE]

[MeindertKuipers]

I have acquired some HP41 equipment that I will put up for sale. I want to offer it here first before putting it on TAS, I hope to find a good home for these things. All tested and working, except where noted. I will sell individual items or all in one sale, just let me know.
There is some more that I acquired, but still needs to be tested. There are specifically 3 disassembled HP41's (2* 41C, 1* 41CV) that could potentially serve as a donor for a 41CL. I also have the CPU boards, but this will take some more time to test. At least one needs to have a new connector block.

Please make a realistic offer. Will ship worldwide, shipping method and costs to be agreed. Will make photographs and provide more details after contact information is exchanged.

You got me excited Meindert, but I see there are no MLDL2K devices here... Sigh... the wait continues...

For want it's worth, my barcode reader also is not recognized by CAT 2, but it works fine on my 41CL with the wand module image plugged in virtually.

Thanks for letting me know. I know this trick works in a real HP41with MLDL2000 or Clonix, the 41CL is something different and I have not tested it. Maybe the Wand ROM is a bit sensitive, this is the second unit that I have see this problem with.

I had one go out on me back when all this equipment was cutting edge. I suspect that it may have been my fault inadvertently pulling and inserting the module with the calculator on. I suspect given the nature of the device it was just more likely for people to be inserting and removing it a lot more than most devices leading to a lot more accidents. You could probably get away with it a few times with luck, but that luck will run out eventually.
