Entry 20th May 2020: Post 2: Amiga 500Plus - Health Check Part 4.

Amiga 500Plus - Health Check Part 4.
It's that time again when I painstakingly open up my A500Plus
computers and check the dreaded battery damage. I have eleven of
the Amiga 500Plus if you count this one. I say that cus the
computer I feature today isn't a 500Plus but an an early Rev 5
A500 inside an A500Plus case. I count this one though cus the
case is for the Plus in the Checkmate. So I could reinstate the
500Plus if I so desired.

So why am I checking these A500Plus machines. Well, all of them
have had the battery removed. Sadly it doesn't end there cus the
corrosion never really goes away. Well not unless you are happy
to scrape the top surface of the motherboard and rebuild half the
tracks, sockets and chips. For those that know the story of Ironman
you will appreciate his dilemma of living each day under pain of
death from shrapnel moving ever closer to his heart. Well it is
like that with the Plus computers. I simply watch the corrosion
and fight it with vinegar and brown paper.  [ like from the
nursery rhyme ].

I tentatively open the computers and through my cringed face I
gaze at the previous damage and simply comfort the computer. My
only joy is switching on and hoping she is working. I can do
nothing. There are those that try very hard to fight the problem
but with so much corrosion and damage to some of these computers
all I can do is live in hope.

In truth it was some silly idiot at Commodores fault. Deciding
to put the battery from the memory card onto the motherboard
pretty much signed the death certificate on any unsuspecting
computer. So many cherished machines were put in store only to
die a painful slow death without anyone ever knowing. That is
no way for any Amiga to die. And so I care for them while I
can and give words of comfort.

And so to computer number four. Sadly this little baby took
a massive hit from the battery and really is lucky to be alive.
When I opened her up the first time my heart was in my mouth
and I feared she was a gonner. Tough little trooper though
and defied the odds and made it through. May look a little
problematic but she works fine and I think I simply managed
to kill the plague in its tracks. Or the computers tracks.

For now the damage gets no worse, though to remove I would
have to grind away at the green with the probable loss of
tracks and sockets plus chip legs. So I just leave well alone
and thank the Amiga gods for keeping her alive.

Note the neat little ROM switcher.

Please note that I am using an old black and white TV for the
images and so they are not the best.
