Here is a strange question. Does anyone happen to know how long unused Laser Printer and Ink Jet transparencies last? Do they go bad, or break down? I have a stack of them, still in the boxes, a lot are unopened. I scavenged them about 10 years ago, when people were getting rid of them.
I wanted them for a Photography Project, that I?ve never had time to try. At this point, I?d like to know if I?m wasting space storing them.

Never mind, I just realised there was a little "+" sign well away from the
symbol that allowed me to select it. It looks like the symbol is somehow
much bigger that how I have drawn it. I should be able to work it out now.

Subject: Can't Select a Custom Device in Eagle
I have been using Eagle to reverse engineer a PSU schematic. I decided I
needed to make a custom device in Eagle for the transformer. I have done
this and it seems to be fine, except that when I put the symbol on a
schematic, after I have confirmed its position, I can't select it, so I
can't move it or anything.
I have done some web searches but I can't find anything about this. Anyone
know what the problem might be?
I am using the free version, and I am on version 7.2.0. Looks like later
versions are subscription only and I am reluctant to do that because they
could take away access at any time.
Thanks
Rob

Hopefully collective wisdom can help on this one - does anyone have a clue
what system this core board was from:
http://www.classiccmp.org/acornia/tmp/coresmall.jpg
The curved edge connectors (presumably to make board insertion easier) are
quite distinctive, plus the way the power's fed in via an edge connector on
the "far" side of the board. What's interesting to me is the core ring
size; the TTL ICs on the board have 1970 date codes, but I didn't think
that the rings got quite that small until right at the end of core's era,
more toward the end of the decade.
It seems to be 8 blocks of 64x64, i.e. 4KB. p/n on the main board of
2001000755, and just hidden from view under the core daughterboard is a
logo that says "LEC", which I suppose might be meaningful.
There's a bigger (2181x1863) image as "coreboard.jpg" in the same dir if
more detail helps (I doubt it), but it's 2.4MB so maybe save Jay's
bandwidth by only looking at that one if you absolutely have to :-)
thanks,

I had one, but sold it to someone on this list last year.
I used a generic power supply, one with multiple cord tips and selectable output. However, when I exhibited the BriteLite and had it running all day, the power supply died after a day and a half.
Good luck on finding a frame buffer for it. I don?t remember the details about it, but I took lots of photos of it.
