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

@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?)

A short overview and history of the PDP-10 family of DEC computers with references to preservation and emulation resources.
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.
Incompatible Timesharing System
A reconstruction of the ARPAnet by @larsbrinkhoff running some of the original PDP10 OSes and an IMP simulator. Fascinating!

Well @retrobytes goes very nerdy¹ about the DEC PDP-10 and builds a replica in the form of a PiDP-10 in an epic soldering montage.
He also waxes lyrical about the TOPS-10 OS for the PDP-10 and it's ancestry to CP/M, MS-DOS and via another route to Microsoft BASIC and a lot lot more more!
Connections going every which way that even James Burke would appreciate 😁
¹ Clearly the best kind of nerdy 🙂👌
