VidHD – Firmware 1.15 & Manual 1.1 Available

The VidHD Apple II video card has new 1.15 firmware with many improvements and fixes. And, a new version 1.1 manual now details the firmware update procedure.

Firmware 1.15 Changes:

  • Fixed sync on 1440p, 1600p, and 2160p displays as long as they also support 1920×1080 or 1920×1200. Displays smaller than 1920 horizontal resolution will not work with firmware 1.15.
  • OS fixes: Linux 4.20.8 and uBoot 2019.01 loader.
  • MouseText: fixes incorrect inverse-checkmark font.
  • Fixed a bug which caused Ctrl-Reset on PAL machines to incorrectly switch VidHD to 60 Hz mode.
  • VidHD PASCAL extended text firmware:
    a. CR now stays on the same line (does not include LF)
    b. Ctrl-_ now correctly moves up one line (also fixed in BASIC)
  • Improved BASIC text firmware:
    a. ESC A,B,C,D are now supported.
    b. Fixed a bug where the VidHD mistakenly thought HOME was called and incorrectly cleared the screen.
    c. Turning off 80-column hardware at $C00C now exits VidHD text firmware.
    d. PR#3 now does POKE 33,40 to prevent HOME from corrupting BASIC at $8xx.
    e. Fixed a few bugs turning MouseText on and off via control characters.
