Is the firmware still there, or is that on the same hard drive? Hi Harald, I still have source code files, they are backed up daily every time changes are made. I was modifying the PCB because I figured out a way of driving the project with one processor instead of two. Updating the HP67 LED display is a processor intensive task, but I managed to get around it. Not sure about the HP65 though as it is more intensive. I was using Protel PCB 2.8 and associated schematic which I have had for years. It does everything I need, is fast, easy to use and the files are still accepted by PCB makers. I think I still have the original floppies, but now no PC for them. I tried the online community based Altium, but is very slooooow to use and will be time intensive to recreate the project. I have almost the latest project design files backed up on a separate machine. When I get home I will open up the drive and see what's what. I was thinking of creating a partition on my laptop drive and run win95 on it. From webbing around, I believe it can be done and I think my original CD is somewhere in a box. There is also a win95 app on the web that might work. cheers Tony |
