For auction is a very rare SCEI Official Prototype Keyboard adaptor for the original PlayStation 1 (PS1). The keyboard adaptor was never officially released but was to be used with the PlayStation modem that was under development. The adaptor allowed you to hook up a PS/2 keyboard and PC standard mouse. This is truly part of PlayStation history!
Was it really used with the internet CD?

In theory, it should have been / was. The Online Connection CD's 'Getting started' on-disc guide clearly shows it in simplified form (viewable in video here: https://youtu.be/2jqbWfRh0bg?t=187) along with making reference in setting up the real keyboard with it.

There's also a second image reference, with it colored differently and having both a mouse and keyboard plugged in (though only the cords) here https://youtu.be/2jqbWfRh0bg?t=59

There are on-disc text files that contain the phrase "Keyboard and Mouse Adapter Initialized" or whatever word they used, so it more than likely was. Considering there is a finalized, smaller retail version that was never released, it's more than likely it was indeed used with the Online Connection CD.

It would have been, if you pardon the pun, a 'key' add-on to have.

I was thinking about something, now that we have this "Lightspan_OnlineConnection_CD" that we can use to test the keyboard adapter.
maybe someone could just make an adapter using an arduino for example, and test it using the lightspan CD.
I'm willing to try it, but I'm not very good at electronics so, no success guaranteed

also I tried to make a modem emulator by pluging my net yaroze serial cable, and openning the serial port on my computer, the speed is 28800 bauds, I get the "AT&F" command from the lightspan CD.
after some trial and errors, I finally get to the PPP packets, now I need to implement this ... I found ppp handling in KOS SDK from Dreamcast. I hope I can get this to work

Rather than mimicking the existing adapter, it should be achievable with a low end atmega 328 or 32u4 or something. All support SPI as they can be used to accept control from Joypads or in Shendos project, a memory card.

Would be pretty cool to get a plug-in working for arduino so we could actually make our own joypad that would be detected by the PS1, then expand this to support mice and keyboards.

If it was achievable to get a joypad running on Arduino, that could be then used to make adapters for other joypds or even make wireless pads etc. Possibilities are endless.

Unfortunately its something I probably lack the skill to do on my own.

I'd be willing to lend someone mine if they think they could decipher something from it.

One interesting thing is that it's using a mask-programmed 68HC05 - which would normally imply these were made in quite large quantities. Makes you wonder where they all went.

I never received anything. It was never sent to me.

Covid happened, and international mail started having issues.
My from Japan packages for example got put on shipping hiatus.

So I didn't want to risk sending it out to where Shadow resides during that time,
but this is still on the schedule to send.

You can send it using FedEx or DHL. These companies are operating fine still :)
