The RT in my office died the other day, and now will only
yield a steady '7c' code on the LEDs on power-up. The
IBM doc that I have is *very* sketchy about what went wrong,
("system unit") so I'd like to know more.
As the problem may just be a loose connector (hope, hope) I'd
like to know where to concentrate on wire-wiggling.
Thanks-
Pat

This happened to me (er, my RT) a few months ago. >As the problem may just be a loose connector (hope, hope) I'd >like to know where to concentrate on wire-wiggling. I'm afraid that the only wire you should jiggle is the phone cord to contact IBM repair... When it happened to me, I tried all sorts of variants (swapping CPU boards, removing AFPA, etc.) without effect. IBM simply came in, swapped the planar (system) board, and I was up and running again in 15 minutes. It's times like this that I am glad I bought a service contract... -- Steve Dyer dyer@ursa-major.spdcc.com aka {ima,harvard,rayssd,linus,m2c}!spdcc!dyer dyer@arktouros.mit.edu, dyer@hstbme.mit.edu
