And now for something completely meta: Interlisp-10 inside Medley Interlisp.

The terminal emulator of the window at center is connected to SDF's PDP-10 system running Interlisp-10 under TOPS-20 (TWENEX). The shell with the terminal emulator and Medley Interlisp are running on Linux.

Mastodon @ SDF
Hoy es el día de la DEC PDP-10, minicomputadora de 36 bits.
Podía utilizar múltiples sistemas operativos. El ofrecido inicialmente por DEC fue TOPS-10, pero su uso palidecía frente al TENEX de BBN. DEC adquiere TENEX y tras modificarlo lo comercializa bajo la designación de TOPS-20, aunque universalmente fue conocido como #TWENEX. Su potencia la hizo especialmente útil para disponer el manejo de redes de la ARPAnet. #pdp10 #retrocomputacion

Lots of activity on the XKL TOAD today 😀

#retrocomputing peeps: Did you know that the SDF runs a publicly ssh accessible #DEC 10 TWENEX server?

Just ssh to [email protected] and login with NEW/NEW.

If you enjoy exploring this stuff and would be interested in helping build a community around it login to the SDF's IRC server and join #twenex

@praetor I’ve been ARPA member since July 2019, but all that additional
things like #Plan9, #Twenex, #Mastodon instance and others … It’s hard to resist to do better support. 👍😀
@BRicker @swaggboi And I know that TOPS-20 a/k/a #TWENEX was also the road not taken as far as network-connected OSes go, that’s why I’m grateful #SDF preserves and makes available the actual hardware to run it
