Eddie, This may not be the best time to ask this, but what are you going to
do with the dead one? The only CMD goodies I have are JiffyDOS setups. I
thought if I had some of their other gear, I might be able to repair it...
assuming I can get parts (likely proprietary) and service data (where?).
Slim chance perhaps, but considering Maurice is not doing anything right
now, I'd like to take a shot.

Actually, Ray, that was included in the bargaining. I asked to have it in
exchange for lowering the price a bit as you might say a "core Charge." I
too, am hoping that I can find the problem once I get it, or at the very
least at least have parts on hand for when I get the money to purchase
another dead one...

Charles,
Yeah, if you can cut a deal, go for it. I hate to see anything useful go
in the dumper. Hope you can fix it... or at least learn more about them and/or
use it for parts. That's what I had in mind. All users of CMD stuff are really
shot down when the equipment pukes and there's nobody around to repair it.

BTW- I also have another question for you. I got a WALLWART PSU that says 9
VDC but is giving me 12 VDC. I do know that if I put a filter of some kind on
the + lead between the board and the wire that it will lower the output
voltage. Question is what kind of filter should I use? A resister maybe?

The output will normally read high on a voltmeter if that type of
unregulated supply isn't hooked up to a load of some kind. Normally, a wall wart
is connected to a device that either doesn't need regulated voltage or has its
own regulation and additional filtering inside. How the source is controlled
and filtered is really up to what you intend to do with it. If you're designing
new equipment, you'd pick a wart with the voltage and current capacity you need,
then regulate and filter it (if necessary) downstream in the powered device.
Wall warts are one way to get around the need to have UL approval for every
device you build that's powered by AC from a wall socket.

Yeah that was my thinking as well. I don't want to see anything
"good" go down the "crapper."


Thanks for the advise on the PSU! I'll see what I can arrange in it
to lower it a bit, maybe a pot or something.... LOLOL
