Hi Don!

The AI PDP-6 and 10 shared a Type 340 between them. It was the only 340 in the lab. Lick's Dynamic Modeling group had an LDS-1 from Evans&Sutherland.

LLOGO could display vector graphics on the 340 or GT40, and raster on the Knight TV or LOGO color TV (16 colors!)

LOGO versions on ITS include BBN LOGO for TOPS-10, CLOGO for ITS, LLOGO, 11LOGO, and Apple II LOGO. Yes, 11LOGO is recovered. There's an early standalone version, and a later version that ran on the SITS timesharing system on an 11/45.

Yes, there are GREN files. I have been in touch occasionally with Ian. Someone else called KLE wrote a FORTH in Maclisp.

True enough, but I'll observe there's a lot of rounding out that could be done in various directions if one were so inclined.

The PDP-4 isn't binary compatible with the PDP-1. There is compatibility within the 4/7/9/15 line. So the PDP-1 stands out, and in that sense the lineage isn't direct.

I laughed (with suitable derision) when I saw the line from PDP-10 to VAX.

Also the dual-mode LINC-8 which was the immediate PDP-12 predecessor. It was as much a PDP in all but the name.

It's both.

LLMs adopted phrases from humans. But now humans adopt phrases from LLMs.

Then maybe also give a nod to the LINC, showing DEC a small 12-bit computer could be made.

BASIC was developed on GE mainframes.

Chaosnet was inspired by the experimental 3 Mbits/s Ethernet in use at Xerox PARC at the time. Experimental Ethernet has a 8-bit node address; Chaosnet has 16 bits, of which 8 is network and another 8 is the node. The Chaosnet data rate is 4 Mbits/s.

On top of the hardware protocol, Chaosnet also defined the higher-level transport and session layer protocol. Applications are addressed by a name string rather than a port number; e.g. "TELNET" instead of 23. This protocol was retained when the NIC hardware was replaced with stock Ethernet.

Yes, and in Ethernet frames as EtherType 0x0804.
