PX41CX

[revwillie]

Today, I finally assembled the PX16c kit that was sitting above my workbench for a while. Having prior experience with the PX kits, I threw caution to the wind and just started from memory. I did goof a little in the soldering of the display board to the header, but it is barely noticeable in the finished product. I will say again that Alex's kits are the best, but it is very clear how much improvement and evolution occurred between the old PX designs and this iteration (to get back on topic). For me, watching a couple of different efforts move forward at HP41 emulation, I am simply amazed at how good the PX41CX is. I think Pierre and Darren and any other of the test subjects deserve credit as well. As usual, the best results are obtained with team effort. In that same spirit, Martin shares a firmware update command file for mac users above.

I definitely understand that some prefer to buy and use the DM41 from Swissmicros. I love my DM42 and if I had been a HP41 user back in the day, I'd probably get the DM41. We can't really assemble our own DM-anything though and I get a therapeutic high out of soldering a kit together. This kit is well designed, planned and tested and anyone still on the fence about ordering should feel confident that it is worth every penny. The old PX41c I've been toying with the last couple of years will soon be re-flashed as a PX 11 or maybe a two-line PX 15 once I get my AVR programmer set up.

Anybody have a favorite trick to test in the Aviation rom?
