Pending final administrative approval of removal from our inventory, I have ~1.5 QE Plus 300's to dispose of. First choice would go to those who would come and claim what they want--I have limited resources for packing and shipping bits and pieces.
We have a fixed tune H/C instrument, a broadband console, and two probes. Most of the stuff has "issues." We have no working monitor left. QE's used a multisync EGA monitor with reversed yoke wiring (otherwise the display would be upside down and backwards). EGA monitors went out of production nearly 20 years ago when they were superseded by VGA, and are very hard to find now. Neither of the GUB boards are completely functional. The one we used had lost the clocking signal for MLEV/WALTZ decoupling and I was providing decoupler modulation externally with a hard wired circuit and a square wave oscillator. The one from the broadband console had a defective lock (completely flat, noiseless sweep signal). Both 1280 computers booted when last used, but I cannot promise that the SCSI disk drives would still spin. The one magnet we still have came down with a deliberate quench, no apparent damage, but I would not bank on reviving it without carefully testing the connectivity of the main coil and the S
C shims. One probe has a double tuned C/P inner coil and is in pretty good shape. The other probe was originally broadband, but was repeatedly well and truly munged so now it only has the outer 1H coil left. There are some other smaller things that don't work either, but I think you get the picture.
Recently there has been some discussion about replacement of pen plotters on these systems. Back in the day when the pens and media were readily available, just expensive, one of my colleagues wrote a DOS application to translate the ZML graphics coming out of the QE to HPGL on the fly. The HP laser printers of the day had a basic HPGL emulation mode and a third party cartridge gave a better emulation. The console we have is equipped with a 286 computer and similar-era laser printer that still works for this purpose. I did a quick check of the executable under Windows XP and it closes down immediately. Nobody here would be interested in fixing it, and I doubt the source code could even be found, but I would be happy to send the executable to anyone who could use it on a DOS or possibly early Windows machine. I also do not know if modern laser printers still have HPGL emulation, or if a vintage printer would be required.
