I've got a bunch of Nuclear Data peripheral circuit boards that I need
to reverse engineer. They are simple circuit boards with all the
tracings visible (i.e. no internal layers) and the parts are all 7400
series logic in standard DIP packaging.
If I were to do this manually, I would take high resolution
photographs of both sides of the board. From the photographs, I would
try to recreate engineering drawings: part placement and circuit
topology.
I'm wondering what kind of tools are out there that would assist in
this. Could I process the photos to extract the topology of the
printed circuit traces? Can I correlate this with image recognition
of the part packages and combine them to product a netlist?
I'd appreciate hearing any experiences from others that have reverse
engineered circuitry.

I make the bulk of my living converting documents in WordPerfect 5 and
up, IBM DCF and Bookmaster, and Interleaf to current formats.
Is anyone interested in hearing a bit about the problems using current
word processors to import the old formats? It's sort of on-topic, as
these are vintage products, even if still in use, but I won't bother
the list if it's not of interest.

My OpenOffice 3.3.0 doesn't explicitly say it
will, but I think I've done it in the past, so I
take your comment as confirming what I seem to recall.

I'm going to plunge into the world of slightly more advanced
electronics, and one of my teaching tools is a Velleman PCS64i that I
just inherited. It's an o-scope front end that interfaces to a PC to
provide the display.
I'm looking for the DOS software - it is not available on Velleman's web
site any more. I found the Windows software, but I'd rather keep it
simple for now. If you have the DOS software please let me know ..
Thanks,
Mike
The setups I have seen require a lot of square footage. You have printers, tape drives, and big DASD farms connecting to controllers and communications controllers and finally the mainframe which may itself be a complex consisting of more than one physical box.
I have not seen a machine room that wasn't all raised floor. I don't know that a small setup exists with the bus and tag technology but that was years ago. The new stuff is smaller and also doesn't need raised floor. Seems like it's probably an either or situation. When you need raised floor you need a lot. When you don't, you don't.

The other problem with raised flooring is who's floor are you on?
With a small system, could a raised island be built, with the computing
equipment raised say a foot or so, with just false floor between the
equipment.

Lots of options it looks like...
OpenOffice / LibreOffice is an opensource way of doing it...

Well, i'll check into that once i get done rebuilding my router! :)
I'll image them and throw them online (my router, coincidentally, is the
only machine with a 3.5" floppy drive :> )
