Configurable on/off and line count using the SET TTY command. I always missed that on Unix. <a href="https://mastodon.social/tags/PDP10" class="mention hashtag" rel="tag">#PDP10</a>

Simon ZerafaWell <a href="https://retrochat.online/@retrobytes" class="u-url mention" rel="nofollow noopener" target="_blank">@retrobytes</a> 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!

The <a href="https://chaos.social/tags/PDP10" class="mention hashtag" rel="nofollow noopener" target="_blank">#PDP10</a> was DEC's big mainframe 36-bit model that CompuServe used to run their service until AOL (who acquired them) finally shut it down in 2009.

🇺🇦 haxadecimalI've at times joked about needing negative propagation delay logic devices, buffers, etc. to meet timing requirements, but I just spotted a -10ns delay line in a diagram in the DEC KI10 Processor Maintenance Manual, figure 5-1.

ChuckWith Oscar's encouragement and my knowing that replacement parts were in the mail so I couldn't make it any worse, I managed to repair the damage to the connector on the PiDP-10 display board and managed to get the tests to all pass!
