[HECnet] Please help to find technical documentation

[d]

Hello Guys,

  After 1 year fight i finally got VaxStation I ( VS20C-F2 ) + monitor 
VRT17-HA. But problem I haven't got keyboard ... and  no cable for this 
monitor to connect to VS ( 5 coax output on monitor to jack on VS)

  Problem that I can't find any technical documentation on VaxStation to 
get part numbers for this cable and keyboard

  Can somebody help?

Thanks in advance,
  Serguei
