Hi,
sombody donates a board to my collection, www.compuseum.at, maybe there is
anybody outside helping me to identify this board.
Its a PDP11 subsystem on an ISA board. Labels found: AT.S, PCCB ROI-931007.
The PDP11 chip is one of this big nice ceramic carrier, holding two chips,
numbers were: HD4-6900-5 DC334, produced 9338, and ...6901... repectively.
As he told me, they used a standard OS2 box to run this 'machine'. He also
will try to find something, but he isn't sure that there is anything left
exept this nice board.
As far as I know, it was part of a building management system, produced by
Landis & Gyr and maybe used or co-developed by Siemens.
Thanks for helping
Gerhard
