PC on the workdesk or the other way around?

At Elektor I am almost singular among the few magazine editors left, as far as having a real-life electronics workspace at home is concerned. Fortunately and forced by social circumstances the place is not as “richly filled” as Jim Williams', which I could not resist picturing above as it is iconic. (photo credit: EDN. Image cropped to suit size prescribed for this e-zine).
My gear comprises oscilloscopes (both CRT and USB), generators (DC to daylight they say), cables, solder tools (10-250 watts), a 2 kilowatt AC line isolation transformer … the whole shebang as many Elektor readers may have it too in their attic, garage or basement. The equipment I use ranges in age from about 1950 right up to December 5, 2016 (yes, today) when I received an Atlas ESR Tester as my Sinterklaas gift. I promise to Sinterklaas I will no longer blow up sleepy electrolytics and put the tester to good use in my ongoing battle against Tantalum & The Badcaps.
I consider a personal computer (PC) a plain tool in my workspace. I need it mainly to quickly look up things on the net, like the pinning of a SCART connector (recognize that one?), tube equivalents, or the proper supply voltages to a MAX232. As you will appreciate, with the typical activity going on at an electronics workdesk, a state of the art laptop or tablet is in real danger of getting some rough treatment most likely from the solder iron or bits and pieces dropping. For that reason, using the “living room” laptop is out of the question too. That’s why I decided to permanently install an old mini-tower PC with a 19-inch LCD screen and running Win 7. I do not care much about the mediocre speed, and this “clunker” is linked to my home network by a 10-Mbit (yes) Ethernet c-a-b-l-e rather than Wi-Fi to keep RF interference in the shack as low as possible. The keyboard is tattered but solid and I am on my second mouse currently as the first one perished under a dropping transformer. I admit there is also an inkjet printer. An even older PC of the 386-turbo class still runs Win 3.11 and Norton Utilities from HD at amazing speed, not just for PROM and EPROM programming jobs but also for playing Alley Cat and helping out with anything requiring real Centronics, real RS-232 or a bit of GPIB. It has an ersatz USB on it that’s horribly slow. Total investment in the two PCs: none.
Rest assured I also happily use a modern laptop with 100's of gigabytes of SSD and an Intel i7 inside and Cloud connectivity outside. I use it to watch Dave Jones' EEVBlog on the couch but hesitate to carry it into my e-workspace. The two resident PCs there are perfectly suited to the job and I am not in the least worried about bashing them because spares are aplenty -- not from RS or Mouser but from friends and the local thrift shop. Plus they make visitors smile.
I’m curious to hear from you, the PC arrangement in your electronics workspace. Maybe you hate the PC, you will have no such thing anywhere in the e-workplace and you are reading this on paper or on your grandson’s iPhone. That’s okay, send me a letter and I shall retype it for publishing here. Maybe your electronics workbench is all-virtual and it comes alive in less than 20 seconds when you open your laptop. That’s okay too, just click on the Add a Comment button below and tell me how you experience electronics that never smells. Everyone else, click on that button too.

I have a PC in the middle, along with my TEAC AH300 and a pair of JBL Control Ones. my amateur radio gear at one end, and the electronics stuff has to perch on the other. The 'scope sits on the corner (Rigol), and everything else gets lifted onto the desk as required. The computer has True RTA as a separate sound source. I work mainly repairing Hi-Fi, tape recorders and Amateur Radio gear.

I have a nice brick built workshop and from the outside it looks wonderful unfortunately to get to the work bench you have to climb over all the accumulated junk i do however have a wonderful collection of test equipment. Theres no room for a pc i just have an ipad propped up where i can.

I use the office PC for downloading data, and have a P4 Shuttle ( XP ) on a trolley down stairs, it's not allowed out onto the internet and only connected to the home network by cable when needed. all my service manuals and component data are on that, ( waiting for Elektor to make an A3 E ink reader ) my bench has the CRO, signature analyser, power supply, audio test amp and probably some otherthings under the rubble. The usb scope and function gen are on the trolly with the PC.

I only have an old clunker scope (25 MHz CRT) which I bought for $80, but it's been adequate. I want to get a PC setup similar to yours - a Win-something PC for looking stuff up and a DOS PC to run an old eprom programmer I have (yes, and for the serial / parallel ports). I do have an NI MyDAQ but I keep that in the office as my only PC is there (hence my office desk looks similar to my workbench in the garage). Dos PCs are great - you get a working prompt in 2-6 seconds after switching on. My windows PC I put to sleep rather than switching off - the wait on booting was getting really annoying. Not very green, but works for me.....

You must have been a very good boy!! Nice!!
All the best for christmas to you and all at Elektor, and thanks for helping to preserve my sanity. The arrivals of Elektor magazine are the high points in my year!

Besides looking up data sheets, schematics and other information I use it to program Arduinos and other micros. The PC is also my only oscilloscope (via PicoScope) and logic analyzer (using Saleae Logic).
Like Brian, I also have a SFF Dell Optiplex 760. It was being thrown away by my company because it didn't work. Some Google research and a new electrolytic put it back in service...
A Dell 24" display with a monitor arm so as not to waste bench space on a monitor stand. A small keyboard with no numeric pad also saves space. So far I have avoided melting the keyboard or mouse when soldering...
Still running XP with no problems :-)

Its an oldish diy built quad core running Linux Mint. I just installed shelving to try to tidy up my meager collection of gear.
The current 'scope -- I change them as often as bed sheets -- is a Kenwood 2160A dual time base; the HP 1740A may go back where it was though. A BK Precision 1590A has been waiting under a layer of dust for a hack to fix the fried keypad CPU so it can reclaim the top spot.
There is an HP204D with a custom power supply, a DIY oscilloscope calibrator square wave generator based on an old Heathkit TTL design, an ESR test device to inject square waves into in-place caps and view waveforms on a scope. I just added a PC supply but often use the computer's USB for powering my tiny breadboard regulators.
Lighting is from Dad's used magnifier lamp and an old drafting lamp. That lights up a marble tile sample I work on for soldering with the Weller WES51, or hot air reflow with the Aoyue 852A++. Generic 50W sonic cleaner and solder fume extractor fan are within easy reach.
A pair of RCA-braded Minimus 7s and a thin but super heavy AudioLogic amp supply the tunes decoded by the PC.
Lots of plastic organizers hold passives, hardware, discrete silicon, plus boxes for ICs and other miscellany. A rolling plasic craft cabinet with drawers holds SMD parts and hardware.
An old HP LaserJet 4M Plus churns out occasinal prints of circuit boards, address labels, etc.
Now if only I could get over my intense equipment envy from that photo... :)

But i do remember my early days back in the 80s doing electronics hobby, when i could not afford to have any instruments except an analog Sunwa MM which works till the day....
