An attemt to show that the logo insert is (a) a separate part and (b) is very slightly smaller than the box it fits into.

A nice, working ASR-33 Teletype. The guy I bought it from clearly didn't think about the ramifications of putting packing peanuts in it. :(
Peek and poke memory - from attached serial console set memory locations 2 thru 24 to their address. Then displayed the memory locations to show that they were properly set.
The main control switches (top) and the 2 DEG PDP 11/34s used to drive the big green ATC screens (one DEG per screen).
The full system in all it's glory with both ATC screens showing recorded data from the playback unit far right. The reel to reel tape is another recording device which we have yet to get working.
I SAABs Karossverkstad SAAB 900 3Dörrars kaross färdas mellan svets stationera på en AGV från Digitron System styrd av ett system men en Digital PDP11 minidator från Digitron, jag jobbad med dessa vagnar i början på 1980 talet, Det var så Intressant att Chalmers data avdelning kom på studiebesök varje månad för att titta på denna minidator som styrde saker i verkligheten vi I/O rackar den ena av 2st i Europa den andra PDP11 med I/O rackar var på Shells raffinaderi i Rotterdam

When I was in school, back when the earth was young and PDP-11s roamed the prairies, I kept saying that after I graduated I'd buy a largish PDP-11 of my own.
They said I was mad, and that the PDP-11 was outdated and I should instead use a 68000 or 386.
Sure, they're _faster_ than the pdp-11, they cost several orders of magnitude less, and they can address a stack of memory, but neither of them have the sublime purity of the pdp-11's instruction set.
Well, I've got the last laugh; behold a pdp-11/73 in shrunken form just waiting for me to figure out how to attach interfaces (aside from the in-firmware serial debug console, which isn't much good if I want to wedge bsd 2.9 onto the box) and rack mount it beside my little pile of ARM sbcs.
The Digital PDP-11 computer fills almost an entire room in Beveridge. It was the only computer on campus, accessed from "dumb" teletype terminals in Beveridge and Palmer. Its computing power is dwarfed by the laptops that today's students carry with them.

I used a DEC PDP-11/20 and a PDP-11/45 while I was a student at USC, so I had to take a closeup photograph of this PDP 11. PDP-11 have a clean, simple, and versatile instruction set.
Newman Solid State RK05 drive. The floppy on the left is actually a 21MB floptical drive holding the main programs for each of the PDPs. When the system is started the contents of the disk are copied to the solid state memory in the unit which acts like an RK05 disk drive.
I threw out hundreds of these, 5¼ see below, mainly XiDEX, a few years after I was made redundant at ACT Forests.
I started computing on a PDP11-34 DEC mainframe, learning BASIC and Fortran, then organised the acquisition of our first 80287 NEC APC-4 and a 8087 based PC for me at home!
I still have a Windows 98, now on NT, (I think, must start it up. I use it to connect to my slide scanner via a SCSI card and fat cables) desktop with a 3¼" drive, I replaced the 5½" with a CD drive...
