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?
8) Anyone got unwanted AIX 2.2.1/Landmark manuals? (Esp. Problem determination guide, Operating system tech ref & RT PC hardware tech ref.)
Massively grateful for any help/comments, please feel free to mail me direct, (it's a bit easier for me that way)
