Hello all,
I succeeded to read it with Corel PaintShopPro XI and then converted it to
PDF with PDF Creator. The PDF file is 113kB but zip down to 96kB. Let me kow
if you're interested, and where I can put it (I don't have a server
available here).
I read that file into CorelDraw, keeping it as a vector file. I used Acrobat to
create a PDF, still in vector format. 42kb.
Brooke, AutoCAD should be able to read in an HPGL. Look at your file suffix options.
sometimes an HPGL file is a .plt (plot) file. That's what Corel wants to see, though
it handled .hpg OK.
In any event, you'll want to keep them in vector format for all the obvious reasons.
If AutoCAD can't do it, send 'em to me or put them up for download and I'll convert
them for you.
I recommend putting the HPG files up too, as they can be directly squirted to a
plotter without having to go through any intermediate process.

Hi:
Thanks to John Miles and his HP 7470 plotter program I have .gif versions of
the five E1938 drawings that were in .hpg vector format that can be viewed.
These are packed into a single file E1938gifs.zip downloadable from:
http://www.prc68.com/I/HPE1938.shtml
The schematics for both the board and oscillator are there along with a block
diagram of the oscillator.
John has a number of freeware programs in his HP-IB Tool kit including
"Automated phase-noise measurement utility for the Tektronix and HP spectrum
analyzers" along with links to related app notes, etc.

Thanks for the plug. :) I should point out that 7470.EXE was never meant to
draw diagrams like this, so the colors and overall line quality are not all
they could be. Jeffrey Pawlan, WA6KBL emailed me with a nice grayscale
rendering of one of the diagrams, although I never did catch what program he
used to generate it. It looked quite a bit better than the 7470.EXE output,
at any rate. If we can get a set of better renderings, I'll make sure they
find their way to Brooke.

When Brooke put up the very first single page of the E1938 hpgl file I converted
this to a B&W 2400dpi PDF and sent that to Brooke. He did not send me any of the
other pages nor did he make them available. So I waited until John received
them and converted them to GIF graphics. They were nearly unreadable here so I
asked John for all of the HPGL files. I converted all of them using an older
program that I use for my CAD/CAM work. It is CAM350 version 7. Its main
function is to check and edit Gerber plots in great detail. I remember
paying around $1K extra for the optional HPGL and DXF conversion capabilities.
I have sent a zip archive containing all of the high resolution PDF files to
John who will then put it up on his website. I am not including the PDFs that
Rick very kindly provided as these are already on Brooke's website.

Hi Jeffrey:
I've posted the jpg versions and taken down the gifs.

Strange, I had no trouble viewing the GIF files with a KDE application
(aside from the inductors).
However I havent tried using a Windows application.

More specifically no text is lost if one displays the GIF files at 4K x
2K pixels or so.
Any good GIF viewer should be capable of this.
I merely used the default KDE application Kuickshow.
Only the inductor symbols in the oscillator schematic display as a line
of dots.
