WTB Option 13 interface boards for TDS510a/TDS640a

Derek Chauran

Hello - I need 2 of the Option 13 RS232/Centronics interface boards/cables/ports for a TDS510a and TDS640a (they're the same part for both scopes). I am not looking to pay fleabay prices for them, as I am a hobbyist and mostly just want them to make these 2 scopes as "complete" as possible. If they are *very* cheap then I may be interested in 4 (to make dedicated "debug" interfaces for these scopes).
