VT180/Robin system help needed

Hi Picked up 2 boxes full of VT180 stuff from a ex Digital employee. Got a keyboard, Vt100 and robin board, small "backplane" board, 2 Shuggart 400L Digital branded drives and 4 RX50-AA drives. Also got a VT100 keyboard and a VT100 power supply and several cables. Seems everything is there except VT100 case/crt...could always build this in some full/half tower AT PC case...still I will hunt for a VT100...this is for collecting and not using really... The owner told me the Robin board was modified to use 1M drives (?). There are a couple ou wire jumpers on the Robin board. Also got some disks, Robin schematics, a few CP/M manuals... Questions:(I have not looked at the schematics yet......) 2 BNC connectors on the Robin board. Whats coming outta there? video? on both? composite? What drives should I be using to boot the Robin? The RX50-AAs or the Shugarts 400L? I see 2 DB25 ports on the Robin board and a larger (DBxx) on the VT100 board, anything special? DIP switches on VT100...whats the deal there? Anything else I should look out for? Anybody know where VT180 info is available...I would like to see the guts of one... Thanks for the Help again Claude The Canuk Computer Collector
