     I would like to build a homebrew logic analyzer using several
parallel banks of ram chips to provide a wide bandwidth.
     What I would like to know is:
	1) What input conditioning do the expensive logic analyzers
	   perform on the input (in particular, which gate types).
	2) Have there been any electronic articles published lately
	   with 'do-it-yourself' logic analyzer projects? (I remember
	   Radio Electronics or Popular Electronics had one around 1977).
	
	One question not pertaining to this... does anyone know of a
 25-100 mhz(!) cheap 8 bit flash converter? I have a paper in front of
me that describes a 25mhz version from ITT for $20, but this is somewhat
slow for my application.
