This is a Northern Computers' N-500-PRG, a programmer for, now, the obsolete N-500 two reader controller.  The box is distressed.  The contents are all intact.

It appears to be unused and comes with a power supply with DB9 attachment, along with the programmer itself.

The box is not clean, but the contents seem OK. A few support people at Honeywell Access Control support group have the manual for this unit. You will still need to be lucky, as they may simply say it's obsolete and unsupported.

Please buy/bid exactly knowing what it is.
