HEWLETT-PACKARD LABORATORY MICROCOMPUTER
AND COULBOURN DATA ACQUISITION SYSTEM

Our laboratory is selling an entire modular microcomputer data 
acquistion system at a very attractive price.  The system is built 
around a Hewlett-Packard 9816S (later renamed as series 200) lab 
microcomputer.  This is a 68000 based micro with IEEE-488 (HPIB)
interface, hard disk, floppy disk, color plotter, and ink jet printer.
The supplied H-P software includes a fast Basic and an extensive
statistics library.

Also supplied is a large assortment of data acquisition products from 
Coulbourn Instruments.  This includes an IEEE-488 interface, system 
power supply, 77" tall equipment rack, 5 card cages, and 48 assorted 
programmable modules for synthesis of analog and digital signals, event 
timing and counting, signal switching and processing.  The Coulbourn 
modules have facilities for both front-panel (switch & knob) control and 
automated operation under program control.  This equipment is well-
suited to many types of experiment control, process control, and data-
logging set-ups.  Similar systems are in use in a variety of biomedical 
applications such as electrophysiology, speech and hearing, animal 
learning, physical therapy, behavior therapy, and biofeedback.  The 
simplicity and flexibility of the Coulbourn modules also makes this a 
very nice system for a teaching lab.

We are selling the entire system (HP computer, peripherals, and data 
acquisition electronics) for $5000.  Original cost was over $28000, 
purchased at academic discounts.  An itemized list of the Hewlett-
Packard and Coulbourn equipment is provided below.  All equipment is 
functional.

These prices amount to legalized robbery.  But we are not using this
stuff anymore, and our budget for new equipment is very low this year.
Reasonable offers will be considered, but we would rather not sell
individual items.
