Hi,
I just saw an unknown to me connector listed on an eBay auction and was
wondering if anyone knows more about an "FS/2" connector.

I assumed it was a typo / poor original copy that shou

Thank you all. It seems as "FS/2" is not a /type/ /of/ /connector/ so

I feel like a Raspberry Pi or similar would fit the bill for this

Grant may be right i.e. there is no device that make a shell or a

One easy way would be to plug in a USB to RS232 adapter into any old
Linux device, like a Pi. Another is to use an RS232 converter card
for the built-in UARTs. I don't know about the Pi, but I've used
such a device for the BeagleBone Black.

I started using the BBB some years ago when the Pi was using a chip
whose specs were secret. Supposedly that's been cured. The BBB
is built on TI silicon that comes with a downlo

It's not that big of a monkey wrench in and of itself. It just does
mean that you're in the minority use case. :-( -- Welcome to the

Please elaborate.
I naively assumed that anything that was running DECnet was doing so to
be able to communicate with a DEC system / OS.

Okay. I hadn't consid

I imagine that even commercially supported distributions will eventually

Fair enough.
