Hi Fred,
Thanks. Yes, I do have another monitor I've been using for the Model 1
(see http://www.classic-computers.org.nz/collection/trs-80-model1.htm) ,
but I'm slowly acquiring the full system. So it's not that I just want a
working system, I'm wanting a working Tandy badged system.
I don;t think it will be much help to you. Most service manuals -- for
anything -- are written assumign you know the principles of that sort of
device. A TV serivce manual is not going to explain how a voltage
regualtor circuit, or the hroizontal output stage, or whatever sorks.
Most of the time official service manuals for such things are little more
than the schematic, the parts lists, and setup/alignment data (for whcih
it's assumed you know how to use the test gear).
In which case, the ancestral RCA information
probably doesn't give you
any additional help.
No, actually it might. The SAMS document, although it has a troubleshooting guide, seems to assume a knowledge of
how a monitor
actually works. What I'm looking for is this generic higher level kind of
knowledge. I could just follow the troubleshooting guide through step by
step but my monitor is 240V, while the SAMS guide is for 110V. There are
If this is the monitor that the SMAS book covers, and the one I am
thinking of, it's actually a 110V monitor in all countries. It's jus that
you and I have them with a stepdown transofemr on the mains input.
bound to be small differences. If I know,
conceptually, what's suppose to
be happening, it will help. I might also stop me electrocuting myself! (-:
That's more likely on he 110V model, which as I said was live chassis.
