In response to the many requests for the autosizing mods on the SONY 1302/1303,
please look for Luong's note entitled "SONY 130[2/3] autosizing why & how",
dated 3-25-90.  He has posted the modification instructions along with some of
his own hints to make things easy.  I didn't realize how popular this monitor
was until my mailbox was stuffed with requests for the modification. The notes
also has some hints on how to set up the CRT geometry corrections such as pin-
cushioning and keystoning that were seen in some of the earlier off-the-shelf
1302/1303 monitors.

One last hint: make sure your VGA cable has pins 4 and 11 grounded (commoned
with pin 5) in order to make the autosense work. (Tnx to Gil Syswerda on a pre-
vious note)

My VGA cable is configured as follows:

         Male       Male      15 pin end
     15 pin end   9 pin end   signal name

	  1          3         red video   
	  2          4         green video 
	  3          5         blue video 
          4------:             monitor ID bit 2	
	  5------:             ground
	  6---:  :   1         red return (ground)
	  7---:  :   2*        green return (ground) 
	  8---:  :   6*        blue return (ground)
	  9   :  :             key (blank, no pin)
	  10--:  :   7*        sync return (ground)
	  11-----:             monitor ID bit 0
	  12                   monitor ID bit 1
	  13         8         horizontal sync
	  14         9         vertical sync   
	  15                   reserved

                      * These pins can be left
			unconnected at 9 pin end

I also connected a line from pins 6,7,8 and 10 to the shell at the 15 pin male
end and from pin 1 to the shell at the 9 pin end.

If you "roll-your-own" cable, you may have to break off pin 9 on the 15 pin
male cable end connector as many VGA cards do not have this pin on the corres-
ponding female connector.

The usual disclaimer applies. Anything you do, you do so at your own risk...
