That means we got to browse the (non-HTTPS) web using no equipment or parts newer than 1986 this side of the network (besides the AUI 10Base-T phy).<a href="https://hsnl.social/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#retrocomputing</a> <a href="https://hsnl.social/tags/theoldweb" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theoldweb</a> <a href="https://hsnl.social/tags/hackaday" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hackaday</a> <a href="https://hsnl.social/tags/dec" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#dec</a> <a href="https://hsnl.social/tags/vax11" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#vax11</a>

Petey P. TwelveHi all, we did our annual PDP-12 demo in Dr. Ted Pedersen's architecture class on Tuesday, and it went really well.In cleaning up / reorganizing after showing off our artifacts, I realized that we have something that I haven't seen on @bitsavers, but I maybe just didn't know where to look. It's a big poster of PDP-12 instructions -- it's kind of like the pocket reference in poster format. It is about 9.5x30 inches (24x76 cm). I scanned it in two pieces on the office machine and stitched it together with GIMP. I'll try to make a PDF version with OCR text. @bitsavers <a href="https://teh.entar.net/tags/vintagecomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#vintagecomputing</a> <a href="https://teh.entar.net/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#retrocomputing</a> <a href="https://teh.entar.net/tags/pdp12" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pdp12</a> <a href="https://teh.entar.net/tags/pdp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pdp</a> <a href="https://teh.entar.net/tags/dec" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#dec</a> <a href="https://teh.entar.net/tags/umdpdp12" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#umdpdp12</a>

Stephen HoffmanThere is a DEC NIC (the DEBNA and DEBNK) with both an on-board VAX chip, and an 80186 chip.Expensive chip choices aside, this NIC could continue to run with the VAX host entirely shut down, if the VAXBI host bus was not specifically reset.Which meant you could successfully ping a downed host, as the VAX and 80186 and firmware running out on the NIC could conspire to process that traffic autonomously.Fun times.<a href="http://bitsavers.informatik.uni-stuttgart.de/pdf/dec/vax/vaxbi/EK-DEBNX-IN-001_DEBNA_DEBNK_Installation_Guide_Aug87.pdf" rel="nofollow noopener noreferrer" translate="no" target="_blank">http://bitsavers.informatik.uni-stuttgart.de/pdf/dec/vax/vaxbi/EK-DEBNX-IN-001_DEBNA_DEBNK_Installation_Guide_Aug87.pdf</a><a href="https://infosec.exchange/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#retrocomputing</a> <a href="https://infosec.exchange/tags/dec" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#dec</a> <a href="https://infosec.exchange/tags/vax" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#vax</a> <a href="https://infosec.exchange/tags/vaxvms" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#vaxvms</a>
