question about 60-pin connector

[mdanh2003]

Hi,

I am trying to build a custom peripheral connected to the 60-pin expansion bus (dual row, 30-pin each, 1.27mm pitch) of the Atari Portfolio. See attached image.

Does anyone how to call this type of connector and where can I get one (both male and female)? I tried searching Digikey, Mouser, Farnell as well as Element14 but can't find any. The closest category is either card-edge connectors or board-to-board connectors, but it's hard to search without an exact name for it.

3D models for this type of connector can be found online, for example here https://www.3dcontentcentral.com/Download-Model.aspx?catalogid=171&id=1317579

Thanks in advance.

Measuring the pitch is the first step towards finding one.

It's 1.27mm pitch, as indicated in my post.

Oops. My apology.

Have you checked at Samtek?

Have you seen https://www.atari-forum.com/ ? I searched a bit and they showed a third-party parallel port adapter that plugs into this connector, so they must be available.

I have that parallel port adapter (and the serial port adapter as well). I believe those adapters were made back in the 1990s and are new old stocks. Let me search Samtek.

The one I saw on the forum was built by one of the members in the 2000s. He planned to put it into production but it's not clear it ever happened.

TE Connectivity (Amp) CHAMP line looks similar. You may have to settle for a board-to-board version.

That is exactly what I wanted! Thanks for the info.

P50-060S-R1-EA is the socket (used in the peripheral) whereas P50-060P-RR1-EA / P50-060P-S20-EA is the connector (used in the Atari Portfolio port). Unfortunately both of them are currently out of stock at Digikey ...
