  Hi all --

Doing some cleaning, I came across a box containing a number of old HP 
boards.  I've had these a long time -- I think someone gave them to me 
when I was still in high school. Based on a cursory search of the 'net, 
these look like they possibly belong to an HP terminal, of the 264X 
family.  (see pics: here http://www.hpmuseum.net/exhibit.php?hwimg=240)

I don't own an HP 264X terminal, so I obviously have no need of these -- 
maybe you do?  They're in decent, but not great shape.  Obviously I've 
no idea if they work.  If anyone wants them, you can have 'em for the 
cost of shipping.  Drop me a line.

The boards I have are labeled in the upper-left corner thusly:

02640-60192 CONTROL MEMORY (these have what appear to be ROM chips)
02640-69192 CONTROL MEMORY
02640-60209 PROCESSOR - contains an AMD fabbed 8080 processor w/hp PN 
1820-1701...
02640-69124 DMA
02640-69112 DSPLY CNTL
02640-60125 GRAPHICS M-CONTROLLER
02640-69126 GRAPHICS DISPLAY PCA
02640-60171 UNIVERSAL MEMORY PCA
