content: Replace the toner with finely ground dried beef and you could print a taco! Add some shredded cheese to the second paper tray... Maybe run it through an inkjet printer with sour cream and hot sauce in the ink tanks afterwards? We could sell this to Taco Bell!

content: Took a glance around and found this printer doc:http://s3.amazonaws.com/szmanuals/84a09f3dfb224e4a68f61dcd23372da9Have to add the .pdf extension yourself but it's from an amazon server and AVG sniffed it, so no worries if your virus protection jumps at it. I only skimmed, but it seems to list the clock speed as 90MHz, then as 80 later on. Looks to be a ARM7TDMI though;http://www.atmel.com/Images/ddi0029g_7tdmi_r3_trm.pdfNot directly related: I'm off to look for a sticky on embedding links and whatnot on SMForums. Is HTML permitted?

But I see people of Mexican origin eating there all the time.Over in my area they've got the "Happier Hour" from 2 to 5 (yeah good math) where they have $1 loaded grillers and $1 tropical style drinks.Since I work the evening shift at work, it's perfect for a cheap meal on the way in.

content: People make jokes, but I've gotten food poising three times in the last ten years and *each* time it came from a different Taco Bell. Last time I walked into the bathroom after I ate and realized there was no soap. I got a bad feeling right then and sure enough...

content: I see all kinds of processors in different equipment we repair everyday. it would be nice to have the time to get familiar with all them. but we would go out of business long before then. printers are so cheap why bother?
