Entry 11th September 2021: Post 1: Serial killer - A4000d modem.
Serial killer - A4000d modem.
I had intended doing a feature on this article regarding networking
Amigas, but when I discovered my old modem lurking in the bottom of
a drawer as I searched for a network cable, I was reminded just
how this modem had been party to me losing two Amiga 4000s.
It was whilst using this modem with my first A4000d that the Amiga
died on me. I had been active on the Amiga groups and the computer
was my primary machine with communicating with the various Yahoo
groups. But she died suddenly and I have never been able to find
out just why.
I had moved my operations to the Workshop and set up with the same
modem on another A4000 that I had salvaged and replaced the main
motherboard. This too however developed issues with the internet.
I gave up with the set-up and moved over to a US Robotics on the
Amiga 1200. I had forgotten in truth that it was this modem that
I had been using, and was reminded, simply cus I recalled the
label I placed on the power plug.
Earlier this year I did some tests and further research on the
circuits on the 4000 and discovered the serial burnt out on the
A4000. What I also discovered was that there is pin on the port
that takes sound to the Amiga. There was various comment on the
groups about the reason for the sound connection on the Amiga as
nothing supported this. The thing is the modem that I show here is
a 'voice' modem and maybe that was the reason for the sudden loss
of the one Amiga 4000 and the failure of the port on the other.
I had no such issues with the US Robotics which I used for a good
period with the Amiga 1200. It is strange how time plays tricks
on the memory as I had thought it was the US Robotics that I used
on the 4000 but realise it was not. Maybe this modem was the true
'serial killer'.
Anyhoo... I feature also the magazine article that was intended
for today's blog but not fully used. It carries with it some very
useful information about networking which may be of use. I also
feature a couple of adverts of the day which relate to recent
topics in blogs. Maybe I'll get round to finding the cable I was
looking for and return to the networking some time in the future.
