From:     AMER NELSON

Last weekend while working on a spreadsheet I glanced away for a
moment and picked up a brief flash from my color monitor.
NOTHING ON THE SCREEN ANYMORE.
I was ready to take the thing apart -- suspected a bum power supply.
My wife came home and suggested we hook up the monitor to her
Rainbow with her cable.  Voila!  The only problem was in the cable.
Lesson -- try something that should be obvious, but isn't always.
I have a friend with a spare color monitor, so all is well.
BTW -- I'm not sure how soon I'll hook up the color monitor again.
Don't do that much color graphics and I find the amber monochrome
monitor much more pleasing to (and easier on) the eyes.

BF>The only name on the printer was DECPrinter III.  I didn't check
BF>the back for numbers, though.  The stand it was on looked very
BF>much like it was part of the printer.

Sounds like the LA120-RO (right option?) which is a printer only, as opposed
to the LA120-(something else) which is a full terminal
(DECWriter).  Yes, as Bill Mayhew stated, it should be fully
compatible with the Rainbow.  It's designed as a heavy-duty printer, and
should last a long time on a Rainbow.

From:     GEOFF REED

DL>   I just saw your note about an overrun problem on an LA-50 printer.
DL>I too have experienced a similar problem, mine began with a blown fuse
DL>on the internal circuit board.  I had to install a slightly larger
DL>fuse to make the printer work at all, and have since had this overrun
DL>problem.  I have been using the printer successfully with the Baud
DL>rate lowered from 4800 to 1200.  The intent being to make the serial
DL>output slow enough that the printer can keep up.
DL>
DL>   As to the proper fix, I believe that the Printer Ready/Busy signal
DL>is not functioning (its output being shorted might explain the need
DL>for the larger fuse.)  The fix in this case would be to replace the
DL>bad interface chip.

There's a file called LA-50.zip here on glacier Peak Rainbow that is a zip
of a textfile written by Carl Houseman, he outlined a repair for a bad capacit
on the circuit board of a LA-50, which is Usually the cause of the overrun
problem. if you can use a screwdriver and soldering Iron, this fix will cost
you mabye $0.59 in parts and mabye an hours worth of time.

From:     DAVID HARDY

Hi Eric,

I am trying to sell the whole unit complete, w/all software, hardware, etc.,
sorry...

As of today, it has appeared in 2 local want-ad papers and 2 local newspapers
for about 6 weeks w/no takers...

This is in the heart, more or less, of DEC country, too...

I am dropping the price of the whole works to $700.00, and I'd like
to see it go to another Rainbow user somewhere, rather than attempt to dump
it off at a scrap dealer for the quick cash.  As I stated in my original
ad, I'd be happy to deliver to any point in the southern
New England area for the first $700.00 cash...

Thanks for your interest...

Dave
