Does anyone have documentation for the later MS780-E, based on the M8375/76 modules? I
have the engineering drawings (thanks, Bitsavers!), but I'd like to find documentation
similar to what exists online for the earlier subsystems (the 1978 docs). I'm
troubleshooting a MS780-E in a VAX-11/785, and I'd like to understand just what
I'm supposed to do about that glaring red LED (it's a misconfiguration indicator
of some sort). I'm getting SBI errors while trying to run the diagnostics, and the
memory subsystem seems the likely culprit. Thanks! -- Ian
