JAE D03 SIO Connector

JAE D03 Atari SIO connector, pulled from an Okidata printer. These seem to be on most Japanese-made ATARI components.

This is a JAE D03 connector used for Atari SIO, pulled from the Okidata printer controller mentioned earlier. I used this to draw a part footprint for SIO connectors and so far this has worked out well. A couple minor adjustments have been made, but the original drawing is still accurate.

Today I received a few connectors I had ordered from B & C ComputerVisions and while they ended up being a slightly different type (side by side photos here) the footprint will work for these as well. Additionally, I pulled open all of the Atari hardware I have here and found that all the SIO connectors seemed to be one of these two types.

The Japanese-made hardware (1010 and 1027) had the thick-based JAE D03 connectors and the other stuff (1050 from Singapore and 800XL from Hong Kong) had some clone of the thin-based part. I had to adjust the outline slightly because the thin based parts have a somewhat larger footprint, but this wasn’t a big deal as the pads all matched.

I was a bit disappointed to find out that the parts from B & C ComputerVisions are pulls, complete with slightly bent / solder-y pins and dirt on them but they washed up nicely and should be fine to use.

For reference, here’s the four different (two types) of SIO connectors I’d found, taken from this post that I made at AtariAge asking if anyone knows of any different part styles:

JAE D03: In all the Japanese-made Atari hardware I have. Thick base, well made. Held down with self-tapping screws or riveted in place. (Photo)
MX 7514-4-13: Received from B & C ComputerVisions when I ordered two connectors. I expected them to be new, but they are very obviously pulls (dirty parts / slightly bent pins / solder on pins). (Photo)
CO12995 5-82-4 MEC-5: Inside a Hong Kong-made 800XL. Appears identical to the MX 7514-4-13. Riveted in place. (Photo)
UNKNOWN: Connector similar to the previous two, in a Singapore-made 1050. I could read TAIWAN on the back, but while I could ensure it’s not the same as the part in the 800XL I couldn’t make out the rest of the part numbers. Held down to the PCB only by the 15 pins and nothing in the larger holes. (Photo)
