When you think of iconic parings, your brain probably goes more to “cookies and milk” than “DEC and Ikea” but after watching [Dave]’s latest on Usagi Electric where he puts a PDP-11 into an Ikea desk, you may rethink that.
The PDP-11 is vintage hardware that actually lived inside of a different desk, once upon a time, serving as the control unit for an FTIR spectrometer. While the lab equipment has thankfully survived the decades, the desk did not and when [Dave] got the unit it was as a pile of parts. He revived it, of course– it’s kind of what he does– but it didn’t get a new desk for years, until his latest shop re-organization.
The one concession to modernity– and missing parts– is using switching power supplies rather than the bulky linear PSU that would have originally powered the unit. It’s a good thing, too, or we have trouble picturing how everything would fit! This particular PDP-11 comes with the high performance vector processing unit in order to crunch those spectrographs, and apparently those chips idle at about 60C, so the desk-case got some decent-sized 120V fans to keep everything cool and running for years to come.
This isn’t the most aesthetic or fanciest case-mod we’ve seen, mostly being made of surplus plywood and scrap metal fittings, but it certainly gets the job done. Given that the PDP-11 has been crammed into every form-factor known to man, from a system-on-a-chip (before anybody really talked about SOCs) to desktop workstations, and of course the hulking cabinets with their iconic blinkenlights-– it’s hard to say that this installation isn’t reasonably authentic, even if it isn’t the original desk.
