Asymtek Spectrum S-820 Automated Batch Fluid Dispenser

This Asymtek Spectrum S-820 Automated Batch Fluid Dispenser looks to
be in good cosmetic condition, showing some signs of wear.
I plugged it in, and hooked it up to my air compressor,
and it powers up, and the computer boots up, as shown.
I opened the dispensing program, and it brought up a box that read,
"Dispenser motor references not found. Select OK to home the dispenser."
I pressed OK, and the dispense head and stage initialized,
as shown in the second thru fourth photos above.
This is the extent of my testing of this system; I lack the knowledge
and equipment to test it any further, and it is being sold as-is.
Approximate overall unpacked dimensions: 55"L x 44"W x 82"H.
