The ICT 1301 Resurrection Project.
Audio Files from the Project
The Sound of a 1960's Mainframe
We are very lucky to have a set of sound files donated by Andy Keene, a former
owner of Flossie:-
So Ladies and Gentelmen, may we present
Flossie Plays Surbiton
These files are available here as MP3 or Low Resolution (WMA) Audio files,
Decide which is for you and then click the links below to download:-
I trust you find these interesting, more files will be added as they are converted.
Andy also included the preparation of the recording session, so here is the startup
sequence for those who want to hear the whole thing.
The Music Compiler
Although there were several card packs that would play music,
my own favoutite was
This allowed the coding of sheet music.
This was quite something on an elderly 1960's computer, the 1301 had limited
speed and so resolution of notes was hard to achive. However by using some
clever timimg loops the program worked well, and even suppoted the playing
of triplets ( just about ).
But who was Arnie ? does any one know who wrote this package ?
More odd Sounds
The running of the machine with the audio monitor turned on gave the busy opperator
ongoing feedback that all was well whilst they loaded paper, or moved trolleys of
magnetic tapes to and from the tape library rooms.
So it is no surprise that some of the NOISES that came from the speaker were well known
Here is a well known sound made by a group of multiply functions, which produced quite
a spooky sound
When you turned the machine in the morning, the sound of the drum's running up was quite
unique, as the powerful three phase motors tried to spin a heavy drum up to full speed.
The thing I always remember is the hovering of the sound at just about the limit of perception.
