Reply to :I note that the Kennedy incremental 7 inch reel drive in the NASA flight case hasn't attracted a lot of interest. That sample tape that I got, however does verify that the parity track on this telemetry stuff is unused. So that explains the 8 data inputs with no parity on the NASA model. --ChuckWell, at least ONE person was interested ... Me .... BUT the vendor does not offerinternational shipping ( to France ), and does not care answering mail :-(Though tape transport is already "packed" ;-)Gerard
