I've tested the pile I brought home with me, here is an update on what works
and some prices. Note that I didn't do a full factory test, I connected
power and a small (.2 amp) DC gear motor and made sure that the controller
would operate the motor properly. It is possible that there are subtle
problems that this qauick test wouldn't pick up, but at least it separates
the "repairable" from the working.
The following work
MM22000A - 0ne availalbe (one reserved for gunner) $35
RG300U - one available, $48
RG51U - one available, $25
RG500UA - one available, $55
The following don't work, but are in my opinion repairable - they produce
field voltage (if applicable) but don't drive the motor properly:
MMRGD10-230AC (this is a very cool controller, if it worked, I replaced the
SCRs, but it's still inop) $12
RG300UA - missing a couple of 2K resistors so I can't complete the test $15
Mystery controller (Minarik), similar to the RG500, but a bit larger, no
heatsink, digital speed select. three of these $8 ea, one missing some SCRs
(that I used on the RG10D above) and some other parts $2
XA970207 - I suspect the diode bridge, will experiment later $12
MAC03 series AC controller, missing a capacitor, a resistor, and a
transistor - very nice VFD (if it works), $18
The following doesn't work and is probably not repairable, but may be good
for parts
MAC08 series, no heatsink, missing a capacitor, a several surface mounted
parts exploded. this is an AC VFD, the CPU is probably OK, the power light
operates like it should, but I'm not going to try and replace the surface
mount parts. This would be useful if you have another MAC08 series drive
(it is not the PWM variant of this drive). $4
I'll post more info when I get into the next box of stuff
Oh yeah, and there is a mystery controller that I put up on E-bay, he

a friend and I picked up a big pile of Minarik controllers last week - I'm
sorting through them now, some are damaged, some appear new, I found a
nice
3 phase VFD that I'm now using (but there don't appear to be any more
working ones of that), lots of boards. the controllers I've identified
are
all for various types of DC motors. For example, I have sitting here a
couple of the RG500 series and an RG51U.
I'm not going to be able to test all of these, though I may be able to
test
some of them - if you are interested, contact me off the list - prices
will
vary - "unknown" boards will be $1 to $10, repairable controllers will be
$10 to $20, ("non-repairable" will be cheaper), and anything that I am
reasonably sure will work will be a little more, but never more than half
of
list (for a testing and workng one), probably a lot less.
for example, I have a couple of MM2000 controllers (manual is here
http://www.minarikcorp.com/PDFs/250-0089.pdf) that appear to be new -
those
will be $35 each
If you have some interest in any of these, contact me off the list by
unmangling my email, below. As I figure out what I really have, they will
go on to E-bay and probably be more expensive.
