o? wonder if these are the same as the ones used by nasa in the psa test point adaptor https://www.icollector.com/Apollo-Ground-Support-PSA-Test-Point-Adapter_i32827980 On Thu, Jun 17, 2021 at 7:47 PM Jon Elson via cctalk wrote: > A while ago there was discussion about the mini banana plugs > used in this system. > > On another project at work, we needed some mini banana > plugs, these sure look similar. > > I found that Digi-Key stocks some, as part # 314-1403 > (black, pack of 10 plugs, for $24) > > and jacks 501-1051 (red) 501-1479 (black) and 501-1959 > (green) for $2.05 each. > > These are roughly 0.1" diameter plugs that squeeze down a > bit when inserted into the sockets. > > Not claiming these are the same size as the DEC ones, but my > guess is they could be. > > > Jon > >
DEC computer lab / mini banana plugs
A while ago there was discussion about the mini banana plugs used in this system. On another project at work, we needed some mini banana plugs, these sure look similar. I found that Digi-Key stocks some, as part # 314-1403 (black, pack of 10 plugs, for $24) and jacks 501-1051 (red) 501-1479 (black) and 501-1959 (green) for $2.05 each. These are roughly 0.1" diameter plugs that squeeze down a bit when inserted into the sockets. Not claiming these are the same size as the DEC ones, but my guess is they could be. Jon
