Hi guys,

I'm planning to build some I/O pods for my HP logic analyser's pattern=20
generator card (a 16522A). Buying new is out of the question, they've=20
been out of production for years and cost a hell of a lot of money on=20
the used market (the T&M dealers are selling them for several hundred=20
dollars a piece).

HP provided the circuit diagrams and pinouts in the 16700A mainframe's=20
online help system -- they consist of an input IDC connector, a couple=20
of ECL-to-TTL converters, and an output IDC connector.

I'd like to make my probes as compatible with HP's as possible, down to=20
using similar-or-identical connectors. The input connector is a standard=20
male 0.1in dual-row 20-pin IDC PCB header, but the output is a female=20
IDC with the same pin count.

I've seen 3M straight female PCB headers at Mouser:

But these are fairly expensive, and right-angle versions seem to be=20
unavailable.

Is anyone aware of a right-angle version of this connector, or something=20
like it, preferably stocked by Mouser or Farnell?

I suppose I could mount the connectors on the edge of the board, but=20
that seems like a bit of a hack to me...

Thanks,
