Re: [M100] Hello!

[Ryan Fransen]

I have confirmed it reads 4.06 volts after approx 24 hours after being 
unplugged from roughly a 24 hour charge.  What is weird, is after the 
suggestion of reseating socketed connections, (I only found one IC with a 
socket) and after reseating it, it booted up fine every time for ~10 times, now 
back to the issue.  Of note, when the issue reappeared after working those 10 
times, when continued off-on finally succeeded once, I noticed the date time 
was reset. During those 10 successful startups however the clock was not reset, 
as expected.

might be worthwhile to just check the voltage on it... make sure the
battery is able to hold a charge at 3.6V and is not a bad battery.
sounds like you keep getting ram corruption.

Good call on the reseat, I will do that as a good measure.

Yes, I've replaced the nicad and have charged overnight, though I haven't done 
anymore troubleshooting to confirm operation of the nicad circuit.

Re: [M100] Hello!

[Lee Kelley]

In your first post you said you replaced the internal battery, I assume
that was the soldered in place ni-cad.   The next step that I would do is
to disconnect every connector be sure the contacts are clean and re insert
it.  This might be all that's needed.  This should include any socketed
chip as well.

Lee, though this trick certainly did work, it seems this needs to be repeated 
each time.  Once turned off, then back to square one.  Something else odd, is 
that the trick appears to work only ~50% of the time, whereas just turning off

Ok thanks. Don't worry about credit or anything. I appreciate the offer
though.

Re: [M100] rex4 oshpark

[Stephen Adolph]

These boards are an experimental design that ups the storage capacity
to 4MB.  However, it needs new firmware and new software, and the
boards are untested.   So, until I ever finish this next gen design,
the boards are useless.  I should never have shared the design.  It is
the only REX board that I had at the lime loaded onto oshpark, so I
thought I would share the file for reference and information only but
never marked it a such.
Simplest thing to do is for me to give you a credit or something, or
pay you for the boards.  I don't need them, I have 3 on hand now to
support the development if/when I get to it.

wrt figtronix design - interesting that a total rule violation makes
it through the oshpark filters.  I'm going to try it out some time,
but I have a hundred REX2 boards on hand that need grinding, but are
perfectly usable.

cheers,
Steve

[M100] rex4 oshpark

[Brian White]

Steven, those rex4 boards came in. Did you actually want them for something
or were you just offering to buy them because you felt responsible for
putting them up on oshpark when they weren't working?

If I can't use them to build a rex, but you can use them to develop the
rex, then you can have them, I don't need any money.

Otherwise I'll just chuck'm.

Or, are they *almost* right and maybe just need some minor hacking, so I
should hang on to them in case you can say how to fix them some time?

Also, you might want to look at those figtronix boards to see how he got
them to cut the holes in half. Or I can PM you his email.
