Add this:
Early high end Dell series (I think!) had this dot matix that glows
yellow and rare motherboards that had POST display built in.
Most of time these devices have limited value beside usual 'easy'
failures for POST stuff to detect and often POST cards and bios
built in post does miss rare unusual failures. I have one that
passed 100% but unexplained failures. Used a expensive diagnostic
tool by Ultra-X called Post Hardware Diagnostic 16 with it's special
bios in place of original bios, was able to find bad IRQ 1 on chipset
itself on first try.
