RT hardware help

Hi,

I have just got hold of most of an IBM RT 125 (6150) and I need help, information and even some hardware....

The system is a Landmark Graphics system, comprising:
	RT Advanced Processor Board
	2x4Mb fast memory boards
	SCSI interface
	Micom interlan NP600A-3 ethernet adaptor
	2xImagraph L10AGC1210-10P video(?) adaptor cards, 1 linked to
	Imagraph Sega layer 6 card with NSI Logic daughter board
	Wietek 300-0046-00 with 3002-0047-00 daughter card (?)

The system has 3 internal hard drives (310Mb each I think) and the obligatory floppy drive. The system came with two Sony Trinitron GDM-1950 monitors and an enormous rack box containing yet more hard disks, a 9 track tape and an optical disk drive for huge read/write optical disks.

However, there is *NO* keyboard, *NO* mouse, *NO* cables & *NO* documentation. I have switched the box on & it runs through it's self tests on the small led with no apparent problem, then sits quite happily humming away, but I can't tell what's really happenning without a keyboard and a monitor cable. 

I can get hold of an old IBM PC keyboard, but it has a 9 pin DIN plug connector rather than the RT type, are the keyboards compatible if I change the plug? does anyone have the pinouts for the mouse, kbd & serial ports? Better yet, does anyone have unwanted RT keyboard & mouse I can buy (cheap + carriage)?

I also need to know cable spec's for the Imagraph card->GDM1950. 
The monitors have 5 BNC connectors; R, G, B, HD & VD, the last two being 		sync in connections. 

The Imagraph L10AGC1210-10P cards each have 9pin female D type 	connectors

The Imagraph Sega Layer card (to which one of the Imagraph L10* cards is linked via a short ribbon cable) has a 9 pin female D type and a 25 pin female D type connector, none of which are labelled.

I have no idea what the wietek card is or what it does.

In summary:
	1) does anyone know the (monitor etc) cable spec for this system?
	2) Can I use a standard PC keyboard, and if so how do I convert from 5 			   pin DIN to RT 6 pin square? Can I convert Logitech mouse (Logimouse 			   P7) with 9 pin D type to RT 6 way?
	3) Does anyone have surplus RT keyboard & mouse?
	4) What is the pinout for the serial ports s1 & s2?
	5) Does anyone know of a Landmark Graphics Corporation contact?
	6) What is AOS 4.3 or 4.3/RT?
	7) Anyone tell me anything else about this system?

Massively grateful for any help/comments, please feel free to mail me direct, (it's a bit easier for me that way), or via NEWS...

Simon

Here is the pinout on the Keyboard,  Don't know if the scancodes are
anywhere near the same, but this came from the IBM Tech Ref Vol I, page 9-23

   -------------
   |           |       pin 1 =  + 5 Volts
   |   5 3 1   |       pin 2 =  Data
   --        --        pin 3 =  Speaker
     | 6 4 2 |         pin 4 =  Speaker
     |       |         pin 5 =  Ground
     ---------         pin 6 =  Clock


The book has a big chart of scan codes and key function output codes,
larger that I want to post and type, but I am not sure how they compare to
a PC keyboard, if at all.

Locator  (mouse or tablet)

   -------------
   |           |       pin 1 =  Ground
   |   5 3 1   |       pin 2 =  Transmit
   --        --        pin 3 =  + 12 Vdc
     | 6 4 2 |         pin 4 =  - 12 Vdc
     |       |         pin 5 =  + 5  Vdc
     ---------         pin 6 =  Receive

Programmable in 25,50, 100, 200 counts per inch  default = 100
Protocol RS232C 9600 Baud async Fullduplex stopbit = 1, odd parity

at reset sends a special 4 byte report sequence 0xFF080000

Stream mode, has a loopback mode,  report function stream is:
  Byte 1  always = 0x0B
  Byte 2  bit 0    1 = right button pressed
          bit 1    always 0
          bit 2    1 = left button pressed
          bit 3,4  always = 00
          bit 5   X data sign  1 = negative
          bit 6   Y data sign  1 = negative
          bit 7    always 0
  Byte 3  bits 0-6  X data   bit 6=LSB
	  bit 7    always 0
  Byte 4  bits 0-6  Y data   bit 6=LSB
	  bit 7    always 0

How this fits a PC mouse I don't know, but every bit of info can 
help when putting things back together.

This info came from an IBM BOOK SA23-2610-0 IBM RT PC Hardware Tech. Ref.

Cheers.. and good luck

Unfortunately, the scan codes don't match up.
