Subject: Apple IIe Motherboard X-Ray
I posted this to CSA2 today. I figured you guys would want to download
these files. If you're anything like me, then you're a digital pack rat. ;

In preparation for cutting my Apple IIe motherboard in half I decided it
would help to have an x-ray of the board. This way it will be easy to
determine the most efficient cut line.
I've included an X-Ray of a Disk II card just for fun.
The X-Rays are at 300dpi. I'm not an X-Ray tech so my calibration was a
little off. Our resident X-ray guy is gone today. I'm not sure he would be
interested in an Apple IIe motherboard any way. ; ) Some areas are dark.
By adjusting "Levels" in photoshop you can bring them out.
The motherboard received a dose rate of 17.84 R/min for the scans and
calibration. About 27 minutes (for 3 scans and a calibration). This would
have been a dose of 482 Rad.
The Disk II card received the same dose rate, but it was in the vault for
the whole time the motherboard was in there. It received radiation for a
total of about 32 minutes. 571 Rad.
To put it in perspective, if a group of people were exposed to that dose
50-90% would die after 30 days. (90% without intensive medical care).
Primary cause of death is internal bleeding and infections.
Females become permanently sterile.
