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...
