The ship was placed into service as the bar at the fundraiser donor dinner last night, along with all the other decorations we built. It worked exactly as expected and was a big hit.
I took a quick video during setup of the event, before it opened, but the sunlight streaking in the camera lens was terrible, the noise level was too high to hear the various sound effects, and you can see that not everything was ready. Video of ship and props in place and working

I never had a better opportunity as even more obstructions and noise occurred until opening and the press of bodies blocked camera opportunities afterwards.

HP 21/MX SYSTEM DELIVERED - ACTUALLY HP 1000 F SYSTEM
As the system was prepared to load on a truck to deliver to my home, the seller discovered it was an HP 1000 F model, rather than the 21/MX, which makes it a much more capable and powerful system than what we expected. The only downside, and this is truly quibbling, is that I downloaded the wrong manuals and schematics. Not much of an issue.

| Power supply front, before I removed it |
I began with the power supply for the processor. Pictures taken at every step will help me get things back together. A friend with HP systems mentioned that I will need to replace the foam. I didn't see any until I opened the power supply box itself, where I found melting corroding foam.

The fix is to solder in an 820 ohm resistor across the cable pins, to substitute for the thermistor with its nominal 819 ohms at room temperature. I did that tonight thus once I am ready to power up, the supply should be convinced it has a good battery connected.
The machine is well configured. It has 256KW of fast memory and several peripheral controllers including one for the 7970 tape drive and one for disk drives that will control my 7906 drive in the rack.

That foam picture brings back memories of cataloging systems at the Yosemite warehouse, where this was a frequent problem. It appears this foam is far enough gone to be flaking off and snowing down. Take great care with the system until you've got it all out. Minimize vibration or you'll have more brown snow. Until you have the stuff removed, always wear a paper breathing mask when working inside the machine.
ReplyDeleteYour best tool is a vacuum cleaner with a speed control. For the "snow", wand in one hand, small soft brush in the other.
Where you can get at solid sheets of foam on flat panels, use a plastic wand with no attachment, turn the motor up, and you can just shave the stuff off by holding the end of the wand flat against the foam and dragging it along. But whenever vacuuming this crap, there is a swirl of small particles that don't go down the pipe, so keep wearing the breathing mask until it is all gone.
