This is a DEC (Digital Equip Corp) 11/03-AA 120V micro PDP system. It was tested some 5 years ago and boxed and shelved. The unit was fully functional and fully tested. It is end user ready and ready to connect to a disk and boot up. This system should work just fine, HOWEVER, we are selling the unit AS-IS since we don't wish to deal with returns. The unit is fine for spares for field service and originally listed at $1199.00 on our web site.

The Power supply is an H780. The boards are:

M7264-YC, M7946, M7940, M8044-E, and M9400-YE.

It has a pair of BC05L-10 cables.

It powers up fine with the fan spinning and when the DCON switch is turneds on, the DCON lite illuminates and the run lite flashes trying to boot. The unit is originally from a DEC 11/785 front end system.

I've taken pictures of the unit and the boards and the rear. ONCE AGAIN: This is a fully tested fully functional 11/03 DEC system BUT being sold as-is.

Our feedback and company reputation speaks for our products... This Unit weighs over 35 lbs so we've marked the shipping charge at $40.00 UPS ground.

We will waive this charge if it is shipped on your UPS number... This baby is the real McCoy...
