Fixing IBM 5110 Extra Horizontal Lines using Sub Brightness CRT Adjustment @xiphod1337

Uploaded May 2022 | Updated September 2026, 2 weeks ago

Brief preview of a problem encountered on an IBM 5110 CRT, where the CRT screen would elevate brightness after startup (and that brightness would not respond to the front panel brightness adjustment). Simple fix is shown. Also, a brief PSU demonstration at the end (different project, but 5110 related).

$Commander X16 Tribute Clips (2018-2023) Extended Edition This video is a tribute to the build-up and launch release of the Commander X16, compiled from segments of 8BGs prior videos. It is the source video for the down-sampled version that was included on the original SD-card content, using a process developed by badmai from the X16 Forum so that it could be played using the VERA hardware. The SD-card actually uses a slightly shorter 5min version, so this is the extended edition. Used with permission from Kevin and David. In addition to being a VERA-capability demonstration (in the on system VERA adaptation conversion), this is also a tribute to their efforts and many challenges on bringing the X16 into reality. Presented here is a sequence of main highlights over the years. 00:30 Kevin Williams introduces Gameduino (their first experiment, 2019) 01:00 Cloantro Commodore ROM/BASIC V2 licensing (this got resolved!) 01:15 Where the Commander X16 name came from (originally was 65816 based! see 05:02 ) 01:40 Simplified back to a VIC-20 baseline (see the original video on why!) 02:02 Two video card submissions 02:27 First X16 board prototype with VERA 02:33 Michael Steil offers Kernal ROM help! (see also his VCF talks) 02:48 Perifractic helps on the logo! (also helped setup original X16 website) 03:34 Nobody *yet* has made a tracker! But then two people did :) 03:40 Sound chip issue (which eventually got resolved) 04:00 Nicco1690 adapted audio for Quarx port (and other audio samples for X16) 04:05 The GoFundMe was a success - provided up front funds to get materials (and tools) to make 100 initial boards! 04:40 Solder dipping station attempted, but Dev board too large (this may get used later for Gen2/3 smaller boards) 04:52 Brief look at the Lazer3D case! 05:02 Kevin mentioned they tried the 65C816 but just couldnt make it affordable (see original video for more in depth reasoning) 05:30 $50 system still the goal! Still Assembled in USA for now (Suntronics) 06:20 Board still needs final assembly and ROM loadout$
