LPT Parallel Port Removable External Drive for Classic PC's and Notebooks

The SDLPT adapter is designed to allow classic IBM Compatible PC Systems to use SD-Cards as a disk file storage device. The adapter is an alternative option to floppy discs and is not designed as a direct replacement for hard drives or other storage devices.

The driver uses a slow SPI (Serial Peripheral Interface) connection through the LPT port to communicate with the SD-Card and this limits the data transfer rate. Typical file transfer rate is comparable to a floppy disk drive at around 30-60 kB/s. Transfer rates also depend on the PC system configuration and LPT port settings.

The adapter is compact enough to not protude too much when plugged into the LPT port.

Locking nuts can be used to secure the adapter in place or a cable can also be used instead

of directly plugged into the port.

Power is sourced from a 5V Mini USB plug or other 9V to 5V 30mA power source.

The adapter can also be powered from a 9V PP3 battery. Minimum 5V required.

Please leave message with email address when making payment through eBay.

Requires a DOS Partitioned and Formatted FAT16 SD-Card (2GB or less recommended).

Some systems may require the parallel port configured for standard mode (Not ECP/EPP)

from within the BIOS for correct operation.

It is not recommended to unplug the adapter while powered ON or the PC is in operation.

(This could cause file corruption on the SD-Card but would not cause any electronics failure.)

A limited quantity of these adapters are currently available.

These cards are built to order so please allow several days before shipment.

The case is 3D printed with Black SLA+ plastic.

PCB Schematic and Driver files will be sent via email after purchase.
