I just noticed that the Intel i960 (1988) bitfield instructions support field widths from 0 bits (!) to the full word size of 32 bits. This reminds me of the DEC PDP-10 architecture (1967) byte instructions, which also operated on bit fields called "bytes", of widths ranging from 0 bits to the full word width of 36 bits.

@larsbrinkhoff got into the act with Javascript and PDP-10 assembler versions. The sources are on Github, and a video of the PDP-10 is on YouTube.

(Lars, what display are you emulating on the '10?)

Interesting …

The original Interim Mail Access Protocol was implemented as a Xerox Lisp Machine client and a TOPS-20 server.

Happy DEC-10 💙

There’s a special hell for this kind of jokes, I know I know

There are a few well known hand drawn maps of the early ARPANet. Are there any of UUCPNet from a similar period?

I know there were nodes that acted as gateways between the two networks.
