Dell Optiplex 320
Model year ca. 2006
Pentium D 2.8 GHz, 2 GB RAM

Sapphire Radeon HD5450 1 GB graphics card (add-on)
2 circulation workstations, 5 staff workstations, 9 public access (adult), 2 public access (children)

Optiplex 320 is the workhorse of our computer inventory. All public access workstations (and most staff workstations) run full time while we are open for business: 53 hours a week.

The library purchased these in early 2007 to replace a hodge-podge of Windows 98 and XP workstations. The integrated graphics processor is ATI Radeon Xpress 1100, but to accomodate the increased graphics needs of Windows 7, a Radeon HD5450 graphics card was added to each one in 2014, and RAM was increased from 1 to 2 GB.

We have had only one of our 19 Dell Optiplex 320's die: a failed motherboard in early 2015 after eight years in service. A couple others have needed a replacement power supply. This has been a very successful purchase for us.

Dell Dimension 3000
Model year ca. 2004
Celeron 2.66 GHz, 2 GB RAM
Intel onboard graphics 82865G
2 OPACs at circulation

Dell Dimension 3100
Model year ca. 2005
Pentium 4 3.06 GHz, 1 GB RAM
Intel onboard graphics 82915G
1 OPAC in childrens' room

Our Dimension 3000 and 3100 units were in-house purchases for circ and staff use, but were shifted to the less resource-demanding role as OPAC's when all the Optiplex 320's were converted to Windows 7 in 2014.

Dell Dimension 4500
Model year ca. 2003
Pentium 4, 2 GHz, 1 GB RAM
NVIDIA GeForce FX 5200 graphics card
1 OPAC in reference room

Given to the library a few years ago by a board member. Despite antiquated hardware, it has been running just fine as an OPAC with the Lubuntu operating system.

Lenovo Thinkpad L512 (laptops)
Model year ca. 2010
Intel Core i3, 4 GB RAM
7 public access

Acquired from Maine BTOP in 2011 to increase our public access computer total (from 9 to 16) without the need to purchase more furniture. Patrons can check out a laptop at circ to use anywhere in the library.

Dead computer!

Dell Optiplex GX270, Model year ca. 2004. This Pentium 4 workstation was acquired through a Gates Foundation Staying Connected Grant. It served us for over a decade, finally succumbing to the dreaded ruptured motherboard capacitors to which this model was heir.
