I finally got around to do some scanning.

Actually the large or color things were photographed with my new (for
me, at least) Olympus SP-310 in raw mode, developed and cropped with
RawTherapee and further edited in XnView and PSP4. (As a result, the
tables aren't too pretty due to slightly uneven lighting by the built-in
flash. Otherwise the cam is great for the ambitious user who wants a
compact with extensive manual control, although it is a bit of a power
hog even with current firmware and could use a faster card interface.)

The alignment stuff was scanned, which took me a while because my
parents' computer was acting up and froze or rebooted like half a dozen
times. (It's the caps I guess, either on the mo/bo which had been kinda
flaky from the beginning, or in the PSU, Fortron or not.) The black and
white level adjustment in XnView (newly discovered and strangely named)
proved to be very handy for eliminating bleedthrough and beefing up the
contrast.

The resulting images were then compressed with DjVu using DjVu Solo 3.1,
which does a great job compressing scanned multicolor and monochrome
stuff - PCB drawings in particular are extremely hard to handle with PNG
(too large) or JPEG (by the time you've got the file size down, it also
looks like poo in the important parts). (A browser plugin that also
comes with a standalone viewer can be obtained at the Lizardtech
website.) Given that viewing is pretty quick and multi-page documents
are possible on top of that, it's a pretty neat format for the web.

Anyway, here's the result:

I'll also upload it to the corresponding Yahoo Group.

Until recently, computers must have worked with toaster logic. A
toaster also has 2 states after all, and this would explain the issues
of heat generation and clock freq scalability (toast change times = c).

Thanks so much for your efforts; the aligment data is
very helpful and is very legible. The photos of the
component placement don't display well for me, however
I took very good photos of both sides of the RF
section and by registering my photos over the co-
ordinate map in your scans I may be able to generate
clear placement maps which I will also post when
they are done. Together with the co-ordinate charts
this will document the board properly for component
call-outs.

At some point I also intend to capture the schematics to
a CAD format.

Thanks much again!

Regards,

Michael
