Re: Getting NAME ERR when I save program raw files

Things seem to have stabilized and I'm no longer getting weird behavior, since I re-flashed with the production firmware again. When I type [shift][CATALOG], I no longer get extra random symbols following CAT like maybe CAT'| or the like. Also, when entering alpha characters into the alpha register,...

I apologize

I would have replied to my previous thread, but it has been locked. I posted that the DM41X had caused my HP 88240B IR Thermal Printer printer head to fail, and this turns out to be incorrect. I had tested it first with my HP41CV with an IR module, and it worked fine. Shortly thereafter, I used it w...

Re: USB connection really flaky

These are the cables I use, never had an issue connecting to any peripheral, including a DM42 and a DM41X. https://images-na.ssl-images-amazon.com/images/I/71P9PplRL1L._AC_SL1500_.jpg Unless the micro USB connector on the calculator side of those cables is somehow longer than normal, then it seems ...

Re: USB connection really flaky

I ended up butchering a USB cable like the photos, but on all four sides, and it goes completely into the socket now. My DM42 never needed such barbaric cable modifications, so I wasn't expecting different from the DM41X (the port is actually better aligned in the case opening than the DM42). Seems...

This is the price to pay for the full 41 micro-code compatibility that allows you to use the large library of modules developed for he HP-41 ;)
Is this true for all modules, or only some ? From what I can tell, program POLY in module MATH works fine with the DM41X set to FAST mode.

Re: USB connection really flaky

... My cable connection is very tight, and the cable is high quality (it's actually the cable that came with my HP Prime), ... Hello Mike, some USB plugs (or their plastic housings) are a little too big for the DM42 (and the DM41X), maybe resulting in a unstable connection. I helped myself with a l...

Re: Speed Test

By comparison, the result on my DM42 with 100 loops is 0.70 seconds So, the DM42 is about 24 times faster than the DM41X with this test. Not entirely surprising given that the DM42 is running native code (Free42 compiled for the STM32 CPU) while the DM41X is an emulator running the 41CX ROM. The di...

Re: USB connection really flaky

Tonight I had a sudden disconnect from my pc that froze the calculator, and when I reconnected after reset, the files in the OFFIMG folder were gone, but otherwise the FAT disk seemed ok. The pc connected briefly the first time, then suddenly disconnected with message that it didn't recognize my dev...

Re: Getting NAME ERR when I save program raw files

That worked. I skipped step 4, leaving LBL POLY in the alpha register. The saved file is not zero byte and there was no error. The only difference is that previously I did not use the CST key, but rather went through SETUP to do this. Also, last time when it didn’t work, I entered poly in step 4. S...

Re: Getting NAME ERR when I save program raw files

It is program POLY in module MATH. Yes, all the programs that I have written work properly now. I can save them whether the alpha resister is blank or contains the global (focal) label name. Thanks for confirming 'normal' programs all work. I can copy and save POLY from the MATH PAC without issues ...
