KXJ11 QBUS card (M7616) with PDP-11 based peripheral processor and
DMA controller. Based on a J11 CPU equipped with 512 kB RAM, 64 kB ROM
and parallel and serial interfaces.
KXT11s are very fun boards. I have one, I like it a lot.
I don't have any KXJ11 though. They are as rare as hens' teeth,
though I do see one on eBay right now for a not-too-terrible price. I
just looked at the auction; it says "10+ available"!!!
I'll bet he'd accept a lower-than-normal offer if it were for a
quantity of them. Bulk purchase?

I thought encryption and commercial messages were strictly verboten
on HAM stuff.
They are. So let's not encrypt stuff. And how much commercial data
flows across HECnet? ;)
So, now that selling DECnet-based internet access to rural areas over packet radio is out, how about we setup some HECnet nodes in Antarctica?

We could do that. I have some satcomm gear here.
(assuming one of our governments hasn't already grabbed that satellite..)

I was thinking about that (also in regard's to Steve's comment about him
having an IP on the 44. amateur reserved net). I experimented with this
years ago, but there was no one around my area to test with.
Wouldn't latency be an issue?
I think it could be handled. Thinking of all the slow links DECnet
was used with in its early days, I'd be surprised if it didn't handle
them well.

What about raspberry pi based weather balloons that also handle HECnet?
