29-page Report, JVM, author. Introduction (from the Report): "In the past several months, we have developed a number of more or less standard logic interconnections using the Signetics 300 & 600 IC families to implement routine functions in interfaces, encoders, converters, etc. This brief is a summary of these circuits, all of which should find useful application in DIPCHIP systems". JVM Note: refer to Page-50 of the TECH REPORT described in Item No. 49 above, for an illustration of the MRC packaging scheme that was compatible with the PDG-Approved IC Logic families
