Giles:

As of June 10, 1997, the construction of the SPARO Data System
by the UC Engineering Center will consist of the following elements:

	CARDS:

	1) A/D component cards (2 operational + 2 spare)
		Each card will be capable of 10 channels. This will 
		allow 9 data channels plus one on-board spare. 
		(40 total channels).

	2) Fiber-optic Logic boards (1 operational + 1 spare).

	3) Nubus/DSP card (1 operational + 1 spare).

	
	HOUSING:

	4) Double Height, 19" rack mount VME Crate. (Will house
		operational as well as spare cards).

	5) A/D battery power supplies, housing and batteries 
		(1 operational + 1 spare).

	
	CABLES:

	6) 32 contact, circular, shielded, twisted pair data cables 
		of length to be specified (a.k.a.preamp to A/D cables, 
		2 operational + 2 spares)
		
	7) Battery power supply cables, power units to A/D Crate 
		(1 operational + 1 spare). Length will be 10 feet unless 
		specified otherwise.

	8) Single Mode fiber-optic cable (2 operational + 2 spare).
		Length to be determined (See NOTE B).


NOTES:

	A) All data connectors will be RF Choke, 37 pin D-Shell.
	B) Filber optic cables commercially available up to 
		10 meters. Any length greater will need special handling
		or construction.
	C) Preamp Design/Construction not within scope of this task.
