Termination
The Host Adaptor pcb carries 4 resistor packs, RP1 to RP4 which are used for
terminating
the
various buses and control lines.
RP1 terminates the SCSI lines from the hard disk controller board.
IMPORTANT
RP2, RP3, and RP4 terminate the 2MHz bus lines and are fitted if the E20 unit is the only or
last peripheral on the 2MHz bus. If another peripheral is attached to the 2MHz bus through
the E20 unit, then these terminators should be removed and retained.
