GENIZN01 at ULKYVM.LOUISVILLE.EDU (Greg Niznik) asks for used neurodiagnostic
machines.
While we do not currently have any working neurodiagnostic equipment to
give away, The NYU Neurosurgery Laboratory has three well-used clinical
evoked potential instruments that it is not using and is looking into
giving away (for the cost of somebody shipping it away).
1. Tracor 3000. a single channel instrument with a 40 mA constant
current stimulator, b/w monitor, software, a large-format DEC-type floppy
disk drive. It was used to obtain somatosensory evoked potentials from
many patients between 1981-89. Has not been used for years. I am unsure
of its functional status.
2. Tracor 3500. A two-channel evoked potential instrument with two
channels of 40 mA constant current stimulators, b/w monitor, intelligent
color monitor, an 1173 DEC computer, a non-working 40 Mb HD, a floppy disk
drive, software for evoked potentials and EEG power analysis. Due to its
non-working hard drive, it has not been turned on for 4-5 years. It used
to work well in animal studies.
3. Tracor 3500. A four-channel evoked potential and EEG instrument
similar to the above, but used for clinical studies of patients, ended in
our lab when replaced by other and better instruments. We have never used
it. Functional status is unclear.
The company (Tracor Northern) that made these instruments is no longer in
existence and the company that took over is no longer supporting these
instruments. Because they use very old DEC computers and many proprietary
circuit boards, it is both expensive and troublesome to keep these
instruments running. The original 3000 was bought in 1980 for about
$40,000. The 3500's were purchased at costs of $50,000 to $100,000 in in
1984-1986. These machines should provide a lot of spare parts for any one
who is running one of these machines or has the time to fix them. They
are big (can be wheeled around) and all three weigh several hundreds of
pounds each.
If we get flooded with requests, we will probably choose from highest
bidders or whatever.
