Line 9: They were available in several compatible speed lines: * 4000-Series: the second series, nominally 500  KHz, but some 1  MHz<ref name=SysMod6>"System Modules", pg. 6.1-6.40</ref> * 1000-Series: the original series, nominally 5  MHz<ref name=SysMod7>"System Modules", pg. 7.1-7.16</ref> * 6000-Series: higher speeds, nominally 10 ~~Mhz~~ MHz<ref name=SysMod8>"System Modules", pg. 8.1-8.13</ref> * 8000-Series: very high speeds, nominally ~~30MHz~~30 MHz<ref>"[http://bitsavers.org/pdf/dec/modules/8000_series/8000_Series_Sep64.pdf 30 Megacycle Modules"]</ref> In addition, special modules were available for purposes such as [[Input/Output]] (I/O) converters (to standard internal voltages), bus drivers, lamp and solenoid drivers, [[A/D conversion]], relays, [[magnetic-core memory\|core memory]] drivers, etc.<ref name=SysMod9>"System Modules", pg. 9.1-9.60</ref> Larger assemblies which are part of the same family provide core memory testing devices. There are also power supplies, mounting panels with slots for the modules, cabinets to hold groups of mounting panels, indicator light panels, etc.<ref name=SysMod10>"System Modules", pg. 10.1-10.35</ref>
