The method for disabling the parallel port on the Model 301Z causes confusion according to instructions in the SYP301Z Installation & Users Guide (pg. 3-24). The Users Guide suggests that in order to disable the parallel port a jumper should be installed between stake pins E11-E12. The jumpers from E1-E10 must be removed. The Users Guide mistakenly implies that the jumpers for LPT1 and LPT2 (E1-E10) may remain in place when disabling the parallel port. If jumpers E1-E10 are not removed the Model 301Z will not boot from hard or floppy disk.

The map below correctly displays the valid jumper configurations.
