The department has used computers for research and teaching since 1971, when
a DEC
PDP-11/20 and
PDP8/e
were purchased. These machines were initially used
for the realtime control of experiments, data collection and analysis.
The first use of computers for teaching was a
computer applications course offered as a third year option in 1973.
The computers were progressively expanded, with major upgrades occurring
with the purchase of a
PDP11/44 in 1981, a VAX 3500 in 1988,
and DEC
Alpha's in 1993-1994, 1998 and 2000.
Personal computers were purchased as they became available, with a preference
for Macintoshes, especially for teaching. A dedicated computer
teaching laboratory using thirteen Apple Macintosh Plus was established in
1989. Currently there are seven computer teaching laboratories with a total of
one hundred and ten machines, and some smaller rooms for use by postgraduate
and honours students.
There is a dedicated graphics laboratory, containing an Alpha DECstation
with realtime video and hardware image compression, a SGI Indy,
two high performance Macintoshes, HP colour scanners, an Agfa slide maker
and various inkjet, dye sublimation and laser printers.
The department is spread across six buildings, with all rooms having
ethernet available. The buildings are interconnected with 1Gb/s
fibre optic cables
and Cisco switched ethernet hubs. Every full-time member of staff has a computer
in their office, and all postgraduate students have a machine available
in a shared office. There are twelve networked laser printers
in various locations
and a local modem pool for staff access. The department has a network
of over 400 computers in total.
Over the years, the department has made several strategic decisions that
has allowed it to be at the forefront of computing in Psychology.
The purchase of the original model
PDP-11 in 1971 was an excellent choice
for general and realtime computing, with the machine still being manufactured
in 2000.
In 1977 we obtained our first licence for Unix which is now the
operating system of choice for workstations and high performance computing.
In the early 80's we had network connections via Basser to the outside
world, initially using ACSnet and finally full TCP/IP.
The early purchase of personal computers and network equipment allowed a
department fragmented across several buildings to have some cohesive
communication and easy exchange of documents.
The purchase of Postscript laser printers in 1985 set the standard
for document presentation.
The use of Webster Multigate gateways for establishing an
extensive AppleTalk network in 1988.
A reliable central computer facility for file serving, print spooling and mail
(lock it away, don't let anyone near it and never turn the power off!).
We had a well defined upgrade path using Unix, from PDP11 (16 bit)
to Vax (32 bit) and then the DEC Alpha (64 bit) architectures.
