I don't think "a fool and his money are soon parted" applies.. Granted, I think it's a little much to pay (not that I mind receiving $109.50, mind you), but he wanted it and he got it. If this purchase makes him content and adds to his collection (makes you wonder what is IN his collection, doesn't it?), more power to him.

I've had mine come blank, but most of the time it's full of random
characters. If it occurs with nothing in the slot, moving the 512k
board pins up & down in their sockets has cured it. For the blank
screen, it's usually the cartridge slot's fault. I think it's revenge
for not using it enough. :-)

I'm looking for a used EPROM eraser, doesn't matter how old or ugly it is,
as long as it works. Also a 21v power supply if somebody can dig one of
those out of your parts stash. Bare wires at the end is ok because I will
be soldering it to a 2-hole header for plugging into the Disto EPROM
programmer.
If you donate it towards the CoCo3.com efforts to create new products, I
will return a Portal-9 or Rainbow IDE registration, or if you want cash let
me know your asking price.
I also want to ask other developers what the most common or popular
Windows-based EPROM programmer might be so I can start looking into adding
support to my IDEs. I definatetly want to let the users burn their
software to ROM right from the IDE if they are creating those kinds of images.

Perhaps more appropriately: "A fool and his money are soon popular"?

Not sure there is any. This is from Microsoft:
main: Program Startup
A special function called main is the starting point of execution for all C
and C++ programs. If you are writing code that adheres to the Unicode
programming model, you can use the wide-character version of main, wmain.
The main function is not predefined by the compiler; rather, it must be
supplied in the program text.
The declaration syntax for main is:
int main( );
or, optionally:
int main( int argc[ , char *argv[ ] [, char *envp[ ] ] ] );
Microsoft Specific
The declaration syntax for wmain is as follows:
int wmain( );
or, optionally:
int wmain( int argc[ , wchar_t *argv[ ] [, wchar_t *envp[ ] ] ] );
The types for argc and argv are defined by the language. The names argc,
argv, and envp are traditional, but are not required by the compiler. See
Argument Definitions for more information and for an example.
Alternatively, the main and wmain functions can be declared as returning
void (no return value). If you declare main or wmain as returning void, you
cannot return an exit code to the parent process or operating system using a
return statement; to return an exit code when main or wmain is declared as
void, you must use the exit function.

Wal*Mart used to sell one. It's a multi voltage 1 amp which is much smaller
and lighter than you would expect given the power ratings.
http://www.allelectronics.com/cgi-bin/item/PS-10
is very similar.
Could
http://www.allelectronics.com/cgi-bin/item/PS-440
or
http://www.allelectronics.com/cgi-bin/item/PS-657
be adapted somehow?

When you see what people pay for things it's clear that too much money is
chasing too few 'valuable' items.

Tony,
Don't feel too bad. I was once asked to name 5 different ways to sort
a list of numbers. Then I was asked to write the code for one on a white
board. Then another time I was asked what C is normally used for today.
The answer was "Embeded Systems". Here is a real kikker. We are looking
at buying some DICOM software. DICOM is medical imaging database
software. This package is written in C and VB. I asked which version of
VB 5 or 5. The answer was Ver 5., which is almost 10 year old. The funny
part is Microsoft is dropping all support for VB 6.0 next year. Not sure
if we are going to buy this package. LOL

As someone who has interviewed programmers for (embedded) programming
positions, I can tell you that it's *extremely* difficult to assess 'coding
skill' under interview conditions.
I've come to the conclusion that the absolute best you can hope to assess is
whether or not the applicant can answer your questions!
I'm still amazed at the generally low level of competence out there -
although to be fair it may be that, as a small company, we don't attract the
'guns'?!? At times we worry that our questions are too hard, or unfair. In
the last 7 years we've only had 1 applicant that breezed through all the
questions in a few minutes - and thankfully he still works for us!

I can see both sides of the argument. I think questions like this assess the
applicant's experience rather than skill. There should only be a handful of
indicative questions for each field - any more than that tends to ring alarm
bells for me that the company culture is one of elitist w**kers who love to
congratulate each other on how 'pretty' their company coding
standards-conforming code is.

My guess would be that, aside from the C startup code, main() in a C program
is the first code executed. OTOH, all the global constructors are executed
in a C++ program before main(), so you need to be careful what you assume.
Good luck with the job hunting!
