I was hoping for some definite direction in my endless quest to fix my C64. I don't
have a lot of free time to work on this. So it is ongoing in many ways. Plus I am cautious
about doing things that I know little about. Which can be good especially when you get
people that give you conflicting advice. I do find a lot of helpful people on IRC, but you
have to sort out what they are all telling you. I won't want to go and start buying
all sorts of stuff and equipment without knowing why or then finding that I should have
bought Y, when I bought X.
I know a little. Bits and pieces here and there, but nothing that will give me confidence
to just dive in.
This is my quest to learn how to repair my C64:
I started with my original C64 which I bought in 1987. I had left it in a garage for two
years and then tried to use it and it didn't work.
First I was told that I should clean my C64 with regular dish detergent and a hair dryer.
I was told that this would solve many problems. Sounds unsafe, but I guess I will try it.
Then I was told that I should buy another C64 since it isn't worth repairing them,
since they are so plentifully available and cheap. So now I have many non-working ones.
Then I need to replace chips that are bad, so I need to know how to solder and de-solder.
Which kind of device to get ? There are different wattages and if you do it wrong then you
burn up your boards (as a friend of mine did with more soldering experience did). Do I get
a combination desolder sucker ? Or a little squeeze one ? Or a push and suck stick ? Do I
get a soldering station ? A braider ? Too many different choices and combinations. I
prefer something that will work and not damage my boards, and for desoldering, something
that won't give me repetitive stress injury.
Then I'm told to get a diagnostic cartridge for C64, which works well expect when the
PLA chip is bad and there you can't see video.
Then I should get a diagnostic harness, which works better, but again you need video.
Then I find a Diagnose 64 cartridge which tells you which chips are bad very simply with
LED lights, but they are hard to find. I'm borrowing one right now from a friend and
figuring out how to use now.
Then I'm told to get a multimeter, how do I use ? Which one to get ? I get one, then
I'm told there is a better that could have been gotten for a little more money.
Then I'm told to get a logic probe. Which one ? Again, how to use ?
Then I'm told a logic probe is not as good as an oscilloscope. Which one ? How to use
? Then I'm told that I don't need an oscilloscope.
Then I'm told to go to Ray Carlsen's site and that will have everything I need.
. Which is very nice, but I'm a
beginner and I don't need just a bunch of schematics and reference material. I need
step by step method which explains which tools, techniques etc. that I need to do.
Then I'm told that going to the Rob Clarke and Bil Herd workshop would give me
everything that I need to know. It is good information, but not hands on.
