PolySCSI Centronics - Computer storage emulation (Hard drive)

The Polykubos PolySCSI is a storage device emulator capable of simulating a hard drive, floppy drive, or CD-ROM drive.

It features a Centronics 50 connector, allowing it to connect to retro computers.

Direct connection (no adapter needed):

• Sharp X68000

• FM Towns II UX series

• FM Towns II with Centronics 50

With adapter:

• FM Towns II (with SCSI High Density port)

• PC-88

• PC-98

To simulate a SCSI hard drive:

1. Transfer a disk image compatible with your target system (you can create one using an emulator like XEiJ for the X68000, or download an existing one online) onto a microSD card.

2. Name the file with the .HDA or .HDS extension to make it recognizable as a hard drive.

3. Plug your PolySCSI into the machine.

Using PolySCSI on a Sharp X68000 with SASI requires installing the SxSI driver (available on the Human.sys 3.x floppy disk).

PolySCSI is also SASI-compatible (for use on Sharp X68000 without installing the SxSI driver). Simply name your image file with the .HDF extension.
Note: SASI has a virtual disk size limit of 40 MB.

Powered via the SCSI port (if power is supplied by the host machine) or externally via the USB-C port
