Onderwerp: HP Integral / display schematic ?
First the TU56 broke, then the Lilith disks goes, and now it
is the HP Integral's turn .
The Integral, stored a year ago in working condition, has a
display problem.
After switching on the Integral makes all the right noises,
but the display remains off.
Anyone has a pinout, or schematic , of the Sharp LJ512U03
EL-display as used in the Integral ?
( there is something, but not much, in the 1985 HP Journal )
a replacement will be hard to find, and far too expensive of course.
I do wonder how those with 100+ computers keep them all
runnning, I have maybe 25 classics and find it hard to keep
them alive.

Jos,
Let it on for a while, I had the same problem.
After letting it on for a few hours, the display came back online.
I think it had to do some regeneration of it's caps...
After that it runs fine, I power it up every few month's
