Is there any freeware around that'll allow me
to draw circuit diagrams like the ones found
in the original XT Technical Reference?
What do Circuit Diagrams drom the IBM-XT Tech Ref look like?
This reminds me of directions I got once from someone:
I was told to make a right turn at the next light then go down the
street (an unknown number of blocks) to the white house that use-to-be
green and make a turn left.
Dia is designed to be much like the commercial Windows program 'Visio'.
It can be used to draw many different kinds of diagrams. It currently
has special objects to help draw entity relationship diagrams, UML
diagrams, flowcharts, network diagrams, and simple circuits. It is also
possible to add support for new shapes by writing simple XML files,
using a subset of SVG to draw the shape.
It can load and save diagrams to a custom XML format (gzipped by
default, to save space), can export diagrams to EPS or SVG formats and
can print diagrams (including ones that span multiple pages).

Or you might look at GammaCAD:

Or this non-freeware one:

Here's what you can do with DesignWorks Lite:
- Draw, save, edit and print complete, professional circuit diagrams
using powerful features like bussing, multi-level Undo/Redo, and
automatic gate packaging.
- Use the library of common 74XX and discrete symbols provided or create
your own libraries using the built-in symbol editor.
- Send compact circuit diagram files to friends or colleagues over the
'net'. They can get their own free copy of DesignWorks Lite to view,
edit and print the circuits.
