The report contains parameters and information on 33 different models of mechanical precommercial thinning and slash treatment equipment. These data were provided by 18 different sources (17 firms plus San Dimas Equipment Development Center (SDEDC) that have developed or marketed this equipment. Also in this document, are results reported to SDEDC on the use of 16 of the 33 models, as well as a discussion of criteria for selecting an appropriate piece of equipment. The data and discussions presented in the sections that follow are provided to assist field units in renting or procuring the proper mechanical equipment to meet the large variety of site prescription objectives that exist Servicewide. Land managers and procurement personnel can use this document as one input among many in the decision-making process; it is not intended to be anything but a quick guide to the current state-of-the-art.

The 168/E is a SLAC developed microprocessor which emulates the IBM 360/370 computers with an execution speed of about one half of a IBM 370/168. These processors are used in parallel for the track finding and geometry programs of the LASS spectrometer. The system is controlled by a PDP-11 minicomputer via a three port interface which we call the Bermuda Triangle. The tape handling and downloading is controlled by one of SLAC's IBM computers via a SLAC built interface between the PDP-11 and an IBM channel. Initially, there will be a system of 6 168/E's which should be able to give six times the production capacity than can be attained by running production jobs on the SLAC Triplex system. The cost of the system, including the channel interface, is $120,000 and yet it yields the equivalent computer power of 3 IBM 370/168's. Hence, this system is an extremely cost-effective method for off-line data analysis. (ERA citation 05:007539)

Performance of the Heavy Vehicle Median Barrier (HVMB) is discussed and criteria for identifying situations where the barrier should be used are presented. The Heavy Vehicle Median Barrier (HVMB) is a modified (42-in-high) New Jersey Safety Shape Median Barrier and is capable of redirecting heavy vehicles such as buses and van-type tractor-trailers with low centers of gravity. It was originally developed to deter errant trucks from crossing the median and colliding with oncoming vehicles.

This document is chiefly aimed at providing assistance to non-technical users in evaluating the applicability of microcomputer-based systems in addressing their needs and choosing appropriate systems. However, technical users providing related support to their organizations should also find the material useful. Similarly, while focussed for Federal users of administrative/management applications, there is general applicability to other environments.

A pair of 168/E microprocessors will be used to meet the realtime computing requirements of the SLAC Hybrid Facility. A SNOOP module and 168/E Interface provide the link between the host computer and the microprocessors. By eavesdropping on normal CAMAC read operations, the SNOOP provides a direct data transfer from CAMAC to microprocessor memory. The host computer controls the processors using standard CAMAC programmed I/O to the SNOOP. (ERA citation 05:007541)
