Hi !
Today I've decided to put my 9010A back to work after 5 years.
It boots OK, but the display is not showing some parts of some letters. For instance the K and V looks like I.
I opened and performed the display test, as mentioned on Workshop manual, and everything seams to be right.
Any clue on that ?
Thanks

Haven't done the display test in years - does it check every segment? If so, and the segments all light up as they should then you may have a ROM issue where some of the ASCII code text in the text tables is defective. That is just a guess, you can check against the code on the ftp site to make sure the base ROMs are all good.
Anyone else with a guess?

Could be the decoder for the display, sounds like it handles individual segments OK, but may a problem with combinations needed to build letters...
