I was looking at my 9005 and grumbling because the tube is missing, then I pulled out the 9010a service manual and you know, it looks like it would be a pretty easy fix to replace the tube with 32 digit alpha-numeric LEDs of the correct size on a small PCB and all that would be needed is to replace the UDN6118 fluorescent drivers with suitable LED drivers and find a place to grab 5V and ground and then mount the new display to the board... Maybe it would work? Anyone interested in poking at the KiCAD layout? I have no free time, but I know there are folks out there looking for a solution to bad or weak tubes...
