UPDATE: DMCP-3.20 / DM42-3.16

Post by grsbanks »

Image

This latest update to both the DMCP and DM42/Free42 parts of the DM42's firmware brings the following improvements:
  • DMCP-3.20
    • Help system: Support for links between files
    • Help system: Numpad-like navigation keys
    • DMCP interface doc updated to version 3.15
  • DM42-3.16
    • Free42 updated to V2.5.20
    • Bugfix: Display repaint during PSE
    • AHelp file: Added description of Free42/DM42 flags
Support for links between files

Help files can now contain links to other files. Cutomised help files can therefore link to each other and to the original help file.

Numpad-like navigation keys

While navigating a help file, you can use the numerical keys like the numpad on a standard computer. So:
  • [8]/[2] to scroll up/down a line
  • [9]/[3] to scroll up/down a page
  • [5] follows the selected link (same as ENTER)
  • [4]/[6] selects the previous/next link (same as ▲ and ▼)
  • [7] takes you to the Contents heading (same as [F2] key)
Update to Free42 V2.5.20

The Free42 Project History Page will tell you what's changed.

Bugfix: Display repaint during PSE

There was a bug that prevented the stack display from being updated when execution encountered a PSE instruction if the virtual variable RefLCD was set to 0. It took the "don't refresh the screen at all" order a bit too seriously...

This has now been fixed. Even if RefLCD=0, the stack is redrawn when a PSE instruction is encountered.

The method for updating your DM42 is covered in the manual.

The latest firmware binaries are available here.

If I buy someone a drink to congratulate them, is it a Mazel Tov cocktail?

Apologies. I didn't update the link to the firmware, only the link to the manual.

Fixed in the original post now.

well, my first firmware update went south nearly immediately. i mounted the dm42 drive and dragged the .bin file to the root directory and it stalled. after a minute or so the mac told me the disk wasn't ejected properly and the dm42 was locked up tighter than a drum.

i did a toothpick reset and tried to load my state file only to be told that it's corrupt. what now?

nevermind. 2nd attempt worked--usb bus must have glitched and the dm42 thought the disk had been ejected. or the mac did although it was accessible on the desktop. firmware update applied but the state file still reported corrupt even though i loaded the clean one and the ee one successfully.

luckily, i worked in computing my whole lifetime and thus am exceptionally paranoid. i've done at least one fat duplicate as a backup every day now including one last night right before i went to bed and the state file from that latest one loaded fine.

i'm gradually getting some programs loaded and my projects for today include uploading the raw program files to the online converter so i can change their names (yes, paranoid and ocd!) and then i guess i'll have to write my own ohm's/power solver or program since i can't find one available or even in the listings of any of the documentation in the hpmuseum cdrom.

sorry for the bother. carry on! /guy

All is fine here although I went thru 2 charge-only USB cables before finding one with data capability.
