DG NOVA4/X runs

Well I just put a cord on it, plugged it in and powered on. No smoke escaped. The CPU passes self-test (no idea what it really checks, but it alleges to be thorough) after I seated the memory board (I forgot just how tough to seat the 15 in square DG boards are). I can poke memory, registers, etc just fine. Took a bit to get the console wired right (to minicom on a laptop, 9600/8/n/1) as the sample cable (from the orig. install) was misleading. The tape drive probably has a bad vacuum sensor; I'll look at it Tuesday again. Might be cable fell off. It otherwise loads the tape and one vac col does the right thing. Other functions seem to work. I have a 2nd tape drive, not yet tested. The disk (10 fixed, 10 removable) is not behaving right. Problem with load/ready. Looks mechanically OK but I will do one more test before the covers come off and the scope and DVM come out. Tom Jennings <tomj(a)wps.com>
