The modifications to the Houston/MSC design of the gas proportional counter flight electronics system are discussed. The following modifications are described: charge amplifier bandwidth improvements, power converter redesign, serial data output buffer, second differentiator, and risetime discriminator. In addition, the redesign of the stellar aspect camera is discussed along with developments in thin film fabrication.

Cosmic ray Li, Be, and B nuclei have been measured using two new detectors, a large-area dE dx-E-Range telescope and a dE dx-Cerenkov-Range telescope. The L/M ratio is found to be 0.23 plus or minus 0.01, essentially constant with energy between 100 MeV/nuc to more than 2 BeV/nuc. Other findings are presented and discussed.
