Summary:
Support for the Medion Titanium MD8800 - External Display (identifies itself as SG-1788 ver 1.0)
16x2 VFD with some additional display capabilities


Description:

I have seen quite a number of people running MP on this machine. In the External Display plugin, I could not find a suitable type for this display. My skillbase is not sufficient to set this up, but here is some research I did:

Here is what it looks like:


Here is some background how people got it to work under Linux:

As far as I understood, it listens to COM1 at 9600 baud 8n*2*, no flow control.

The following commands have been identified so far by Martin Møller (octal notation):

\33\0abcdef (abcdef can be anything, it seems) - set clock, I think.
	   	The mapping is: bb:aa dd.cc.eeff
	   	Date values are entered in hex, e.g. :
		0x18 0x08 0x05 0x04 0x20 0x06 for 8:18 04.05.2006

\33\1 - 24 hour clock
\33\2 - 12 hour clock (AM/PM)
\33\3 - Stop clock from moving around
\33\4 - Moving clock
\33\5 - Show clock

\33\40 - 2-line mode, clearing at end of last line.
\33\41 - Only write to line1, no clearing, 
         automatic scroll to the left when display is full.
\33\42 - Only write to line2, no clearing, 
         automatic scroll to the left when display is full.

  (d is in the range 0-4. Anything above 4 is full brightness, b = 0/1):

Anything is appreciated! As I own the machine, I am volunteering as a tester (given 1-2 weeks time).

Thank You,
