Problem: Programs 90-91-92 (develop-etch-strip) lost
Cause: Glitch
Solution: reprogrammed back in

>>> 'aptchrome' problem from marilyn -- Tue Feb 27 16:16:37 1990 <<<

Problem: APTchrome has been randomly loing programs; this has happened
         three times within the last  1 1/2 weeks.
Cause:   Bad board?
Solution: Each time a program or programs have been lost, they have
          been reprogrammed back in.  However, this is a temporary
          fix.  The aptchrome is able to be used as long as it is
          reprogrammed.

Pump for Shipley Microposit Developer Concentrate is not working (see
Phill's report). This is the chemical used to do the final PR strip
after etching chrome mask. You can still use Prog. #90 (Develop),
#91 (Etch), #92 (to expose PR using lamp), however you must hand strip
the PR after #92. This can be accomplished by using a petrie dish full
of Shipley Microposit Developer Concentrate and simply immersing the
plate in this solution for about 30 seconds. You can then use the apt
to rinse and spin dry your plate by skipping through steps 1, 2, and
3 in Prog.#92.
