Re: PCM-5822 and mono lcd?

From Wear-Hard Mailing list Archive (WH) Maintained by R. Paul McCarty

Check out the 7" 800x480 Lilliput monitor. You can get it for $250 on ebay. 
Analog VGA input
Probably needs another power supply in addition to your 5822
Definitely not the best use of power, but it just works.

To get the STN display, which is very different from a TFT display in
driving, you will probably need to contact Advantech and see if they
have a BIOS update for the LCD driver on the 5822.

You could get the Epson kit, for $199, with an ISA card to drive the
board, then get a PC/104 - ISA adapter.. a little bulky but it would
work.
