95LX file transfer woes and backup battery tray
2022-09-28
Yesterday while setting up the file transfer between the HP 95LX and the Linux box I noticed that I'd bent one of the pins on the 95LX's serial connector. Luckily it was one of the outer pins, not the inner two which actually carry data. I returned it into the correct position with some difficulty, using tweezers.
Script for lDebug (SLD) file for the HP 95LX, and more lDebug development
2022-09-25
Having adjusted the R, U, D, and E commands to be more 40-column friendly I am currently using the following script for lDebug (sld) file to set up the debugger:
r dco or= 800 r dco6 or= 1200 r dco2 or= 111 r ior = #16 r ioc = #40 r dao or= 80
More HP 95LX adventures
2022-09-20
Yesterday I loaded a bunch of files onto the HP 95LX, intending to read on the device. I used some nondescript "PDF to text" website to gain plain text from two PDFs. Next, I attempted to convert the resulting Big Text File from the UTF-8 encoding to Code Page 850 using iconv. This repeatedly complained about invalid codepoints. I manually search-and-replaced all the smartquotes and friends (using Pluma, the text editor of the MATE Desktop Environment). After that I wrote a small scriptlet to make iconv point me to the next invalid codepoint, so that I could replace those manually. (These were mostly CJK, Russian, or Greek sniplets in the text.) After having processed about one third of the Big Text File I figured out that iconv has a switch, -c, which will make it skip invalid codepoints. (I am not sure whether they are omitted or replaced by a placeholder.)
95LX hang, PDZM, Zip, lDebug line history comments
2022-10-11
The other day I managed to hang the 95LX again, to the point that Ctrl-Alt-Del did not work. This time I used Shift-Ctrl-On to reset the system. This reboots and queries whether to re-initialise the RAM disk. I chose "No". I found that while the disk contents and settings where preserved, the current date and time were not. (Supposedly this way of resetting may damage the RAM disk contents even if you reply not to reset the disk memory. So perhaps don't repeat the experiment.)
