BOOT PROM AND JUMPERS
The socket labeled Ull is provided for a boot PROM for
applications where the Transporter card will be installed
in a diskless workstation.
Closing jumper EI puts +5 VDC on pin 1 of device UII.
This jumper should be closed only when a PROM device
requiring +5 VDC on pin 1 is used. Jumper El should be
left open otherwise.
