My RT crashed and burned this past weekend and now on power up it simply reports "7c" in the LEDs. This is before any attempt to access the floppies, so finding and running diagnostics doesn't seem to be an option. The cheat sheet I have reports that "7c" means "Bad APC on IOCC--fatal". Swapping APC cards doesn't seem to have an effect. Anyone within IBM who might have an idea of what's wrong and how to fix it? -- Steve Dyer dyer@ursa-major.spdcc.com aka {ima,harvard,rayssd,linus,m2c}!spdcc!dyer dyer@arktouros.mit.edu, dyer@hstbme.mit.edu
