Note. FDD shouldn’t be directly connected to the J4 connector. Before using a Floppy
Disk, an adapter must be inserted between the parallel port flat cable and the Floppy Disk
Drive.
HOW TO USE THE PARVUS FDD ADAPTER
There are two configurations available for the Parvus FDD Adapter:
1. - J1A :Male configuration (for plugging to the Floppy Disk Flat Cable)
2.- J1 :Female configuration (for direct plugging to the Floppy Disk Drive)
J2 :Power supply (5V) used to power the adapter.
(This connector can’t power the FDD that needs its normal power
supply).
J3 :Parallel Port Flat Cable Connector
A picture of this adapter is shown below.
