Orac speed control (again)

[davidfenner]

Thanks for the earlier info re brown pestel. The manual obtained with the machine specifies a BP unit, but the only ID on the boards suggests its a Parametrics. Three separate terminal blocks, TB2 power in, TB3 power out, (these two self explanatory) and TB1 the control signals. Is there any info available on connections and signal format to this six way TB1. Thanks in advance
